Chava Angell – nanoengineer and science communicator

By Kritin Karkare

Ask nanoengineering Ph.D. student Chava Angell if nanorobots are going to take over the world and she might just chuckle at you. It’s a question she fields all the time at nanoengineering outreach events, but it never gets old. Her passion for sharing nanoengineering has led her to participate in a San Diego Comic-Con panel about the perception of nanoengineering in society, and the UC Grad Slam research communication competition. She also co-found the NanoXpo showcase at UC San Diego.  

“I think a lot of people view nanotechnology as this magical force,” Angell said. “But it’s very tangible. It’s not inaccessible. I want people to understand it’s just manipulating materials on a different scale.”

As a graduate student in Professor Yi Chen’s lab, Angell manipulates DNA to make nanomachines that could improve drug delivery. She builds 3D structures out of the genetic material, taking advantage of DNA’s different properties like responding to small molecules and changes in pH. In addition to medicines, these nanomachines could deliver proteins and other biomolecules where they’re needed.  

Her DNA robots are meant to solve a common issue when drug molecules are absorbed by a cell: Once a molecule enters the cell, it triggers a process where the cell turns part of its cell wall inside out and produces a compartment called an endosome, which holds the drug molecule inside. Unfortunately for the molecule, the endosome typically merges with lysosomes, which break down the molecule and prevent it from reaching its target. Angell’s approach is to take advantage of the acidification process that endosomes go through. She designed the nanorobots to respond to the endosome’s decrease in pH and expand, letting the molecule break free and continue on its journey.

She’s convinced that DNA nanotechnology like this could be the way of the future.

“It’s pretty bio-compatible. It’s easy to make structures out of as long as you follow certain design rules. It’s easy to target certain populations of cells,” she noted.

Talking nanoengineering

When she’s not working with DNA to improve human health, Angell is often found explaining her work and the field of nanoengineering, making it easy for everyone to understand. Participating in the Comic-Con panel “Nanotechnology in Sci-Fi: Fact or Fiction” was one of her favorite experiences. At the panel, she helped dispel some of the myths behind the nanoengineering commonly seen in movies and TV shows. For example, many people wonder whether the Nanites in Star Trek—nanorobots that took over space ships and founded their own civilization—exist in real life and could take over Earth. Angell helped quell that fear to a room so full that people had to be turned away.

NanoXpo in 2017, which she helped co-found.

 “Honestly I was surprised by how many people wanted to learn about nanotechnology,” she said. “People wanted to know what was possible.”

She said it was cool to see the level of interest people had, and know that there were people from all over the world interested in nanotechnology.

While she’s confident in her ability to communicate nanoengineering to different audiences now, it wasn’t always that way.  

“I needed to force myself to be comfortable with it,” she said.  

Years of participating in public outreach events like Comic-Con and research talks eased her worries about public speaking.

Angell expanded on this vision of practicing communication while co-organizing NanoXpo, a research conference devoted to showcasing the UC San Diego NanoEngineering Department’s different research groups.  The event included a poster competition judged by industry representatives and a networking reception. Graduate students had the chance to connect with industry partners, as well as with other students from different labs.      

Angell is aware that not every graduate student is as motivated to practice communicating as she is, but says there are real benefits to it.

“As an engineer, you need to realize that especially as a Ph.D. student you’re defending your thesis to people who have no idea what your field is,” Angell said. Being able to convey your work and the importance of it is vital.

She believes that creating more opportunities to practice communication will encourage more students to talk about science with people in their field and the public.  

As for whether nanorobots will take over the world? Angell says it’s not likely.

IDEA Scholar: Manwinder Uppal

Environmental engineering student Manwinder Uppal was eager to get involved in the IDEA Center before she even arrived on campus. The summer before her freshman year, she saw that IDEA hosted a summer engineering program to orient new students to campus and share some tips to make the coursework a bit easier.

“Neither of my parents and none of my family members had gone to college so that was something that I needed,” Uppal said. “I got super excited and thought ‘Yay, an intro to college life!’ As soon as I came to campus I got lost for two hours, so it was good that we had an intro week.”

Since then, she’s participated in skills workshops run by IDEA on things like the python programming language, and was part of the JUMP mentoring program. She also branched out on campus, finding community through the Raza Resource Centro and Women’s Center, and encourages other students to do the same.

“I wish I knew more or went to the Women’s Center and Raza Resource Centro a lot more, because I basically live there now,” she said. “That whole area is really student oriented. When I did have way too much of an overwhelming situation going on with school or something I could talk to one of those advisors easily so it made it homey. That’s what solidified home away from home for me.”

She’ll be working for a year while deciding how best to accomplish her goal of making an impact through sustainable design.

IDEA Scholar: Tania Vazquez

Tania Vazquez learned a lot at UC San Diego—about engineering, and about her approach to life. A first generation college student, Vazquez spent most weekends her freshman year driving back home to Riverside because she missed her family and didn’t feel at home on campus. At one point, she considered transferring to a school closer to home.

Encouragement from her fellow IDEA Scholars and program director Gennie Miranda to stick it out one more year helped her find her place, and learn the importance of channeling fear.

“I realized that a lot of other people had the same fear I had too,” Vazquez said. “I learned that you have to do things even if you don’t quite feel ready for it.”

She pushed herself to get involved with the Humanas Unidas group on campus, even serving as social chair.

“That was the whole point of pushing my boundaries, because I’m not a very social person, but I decided OK I’m going to go for the position that makes me the most uncomfortable.”

She ended up learning a lot and actually enjoying it. She got involved in outreach activities, and dove head first into classes and projects. By her second year, she felt more comfortable on campus, and was sticking around for more weekends.

She said the IDEA Scholars program helped her find her footing and community on campus.
“It helps you make friendships I think, which makes the process a lot easier. If it weren’t for the IDEA program I don’t know if I would have stayed.”

She encourages students who find themselves where she as just a few years ago to remember that they are qualified to be here and belong here.

IDEA Scholar: Ricardo Rueda

Ricardo Rueda was really good at math and physics growing up, but had always thought about becoming a doctor one day. After learning about the intersection of engineering and medicine in high school, he was hooked on bioengineering.

“I started learning about the intersection between engineering and medicine-- it seemed so scifi to me, the things that were going on. It was amazing and I wanted to be part of that,” Rueda said.

A first generation college student from a border town on the Rio Grande in Texas, Rueda was accepted into UC San Diego’s bioengineering department—the 2nd best in the country—and set off down a path that would include research in two professors’ labs, launching a company that provides in-home health monitoring through AI, and a plan to work in the biosensor industry after graduation.

He credits the first step of that process to being an IDEA Scholar.

“IDEA honestly kick started my whole research experience,” he said. “I knew I wanted to do research, and they helped me kick start that passion through the JUMP mentorship program. My mentor had an opening in the bioengineering lab she worked in, so that’s where I started off my research.”

After a year and a half of working in Professor Robert Sah’s Cartilige Tissue Engineering Lab, Rueda’s interests moved more towards bioelectronics. When an opening in Professor Joseph Wang’s Nanobioelectronics lab came up, he jumped at the chance.

Rueda worked on sensing glucose through sweat, and helped develop a microneedle system to deliver targeted drugs for cancer therapy. He plans to work in industry on similar types of bioelectronics systems after graduation.

In addition to the IDEA Center’s mentorship program, Rueda worked as a peer educator for IDEA’s Education Learning Communities, leading weekly review sessions for physics courses, and said IDEA’s summer program was hugely beneficial, as well.

“It kick starts you with a group of people that are in the same vibe. They all have a passion to excel and having this group of people to grind through difficult engineering courses makes a huge difference. It’s helped me build a great network and incredible friendships.”

Rueda’s advice for students is to embrace asking for help.

“Don’t be afraid to reach out to people and ask questions,” he said. ”There are many positions to fill and opportunities to take advantage of on this campus. Sometimes half of the effort is just reaching out to the right person and even if you don’t get to that person on your first try, there will always be someone more than willing to direct you to the right place, especially at IDEA.”

IDEA Scholar: Melissa Perez

IDEA Scholar Melissa Perez decided to pursue engineering on a bit of a whim.

“I always liked math, but I didn’t really know much about engineering to be honest—there wasn’t much exposure to it at my high school.”

Four years and a degree in mechanical engineering later, Perez said she made the right choice, and is excited to start a career at Collins Aerospace this summer, where she previously interned through the Jacobs School’s Team Internship Program.

Perez said the IDEA Scholars program provided her with access to valuable technical workshops and mentors, but most importantly, connected her to a community of people that pushed and supported each other throughout their undergraduate careers.

“IDEA Scholars helped because coming in I already had friends that I met through the summer program,” she said. “And I think the people I met in IDEA Scholars had similar backgrounds to me, we kind of had similar experiences. We were all in it together.”

Those similar experiences, for Perez, included starting at ground zero with engineering.

“In high school, other people had robotics clubs and classes, and my high school didn’t have any of that—I was coming in here with no knowledge. It was kind of scary, but it has to fall back on you—pushing yourself to learn these things and not being scared of saying ‘I don’t know how to do this, but let me try and learn.’”

Perez got her footing, and wound up serving as a peer facilitator for the IDEA Center’s education learning communities. She planned weekly lesson reviews for calculus, and provided students with homework and test preparation support.

She also joined Eta Kappa Nu (HKN), the electrical engineering honor society, even as a mechanical engineering.

“I really liked it because I got to meet a lot more people from different fields. My engineering friends I had before were mainly from mechanical engineering classes, but now I have a lot of electrical and computer engineering friends, too.”

Her advice to future students: get involved!

“I was kind of overwhelmed in the beginning from classes, but looking back I should have joined groups earlier. Getting involved in clubs helps you meet new people and broaden your horizon.”

IDEA Scholar: Juan Maldonado

Juan Maldonado has had his eyes set on the stars since he was a young boy. Any time in the library was spent in the scifi section.

“That’s where my mind was-- the future,” Maldonado said. “I liked learning about these new technologies coming out, especially rockets. I was really interested in rockets.”

After watching SpaceX launches, and particularly the landing of the Falcon 9, Maldonado decided he wanted to work on rockets. As an aerospace engineer, he had a chance to do that through the Rocket Propulsion Lab and Triton Rocket Club. As an undergraduate, he also conducted research in Professor Nicholas Boechler’s lab.

After graduating from UC San Diego with a degree in aerospace engineering, Maldonado is pursuing a PhD in Aeronatics and Astronautics at Purdue University, while also preparing to apply to be an astronaut.

“I’ll be learning another language—probably Russian—and learning how to fly planes and things like that,” Maldonado said. “That’s something I’ve been interested in since I’ve been a little kid, was applying to be an astronaut.”

Maldonado’s decision to study at UC San Diego was largely influenced by the IDEA Engineering Center. Their overnight program “was awesome,” and the summer engineering program was really helpful, too.

“One of the big things for IDEA that I really appreciate was just getting to know other people and developing friendships with people in my major that I see all the time,” he said. “I still have those friends now which has been super awesome.”

The summer program in particular was so beneficial that he served as a peer facilitator for classes behind him.

His advice to students is to give research a try if you have the opportunity. You never know where it might take you.

“Before I did research I was pretty set on going into industry,” Maldonado said. “Whenever someone brought up grad school I was like ‘Oh nah, I don’t want to do more school,’ because I didn’t know what research was like. But once I did it I fell in love with it-- having to come up with creative solutions, the whole process of doing research. That’s what convinced me to go to grad school-- I didn’t know I wanted to do that until doing research just last summer.

For people out there who don’t know or who might be in the same boat as me and think they don’t want to, if they have the opportunity I’d really recommend they do research because they might be like me and really end up liking it a lot.”

IDEA Scholar: Jasmine Chiang

IDEA Scholar Jasmine Chiang wasn’t sold on electrical engineering when she first learned about the field—it seemed like a lot of chips. But when she found out that electrical engineering underpins how all forms of electronic communication happen, she was hooked.
“All wireless information being sent, all of that needs to be done through signal image processing, and that’s my specialization now,” Chiang said. “It’s such an important part of our lives, to be able to have signals processed efficiently so we can actually send them in wireless communications.. I want to ensure that the technology for people to communicate around the world and even to outer space continues to be revolutionized.”
After graduation, Chiang will return to UC San Diego in the fall to earn a master’s degree in electrical engineering with a focus on signal image processing to make that happen.
“When I first learned about signal image processing I was thinking about its use in music—a lot of it requires filtering and understanding of signal processing,” Chiang said. “So I was honestly hoping I could pursue that. But I recognize now that I’m taking all these classes and meeting all these people and realizing there’s so much more I can do. I’m hoping a masters will help me narrow it down and focus in on what I want to be pursuing as a specific job.”
In addition to being an IDEA Scholar, Chiang was involved in the IDEA Center’s JUMP mentor program and was a peer facilitator at the Summer Engineering Institute for two summers, after experiencing how beneficial the program was.
“I knew when I did my summer program, back when it was Summer PrEP, that I really wanted to be a leader for future classes to inspire them to stay in engineering.”
She also studied abroad at King’s College i London, and was vice president external of the ECE Undergraduate Student Council and was on the ECE Day committee board in joint with the other ECE student organizations.

IDEA Scholar: Cindy Ayala

For mechanical engineering student Cindy Ayala, the IDEA Center and IDEA Scholars program knew what she needed before even she did.

“Through the Summer Engineering Institute, they gave us resources before we knew we needed them,” Ayala said. “In the same way, they gave us mentors before we knew what questions to ask. But then when the questions started to come up, we knew where to go and what resources to look for.”

For Ayala, those questions centered around graduate school.

“I was leaning towards going into industry when I first got here and didn’t think I’d be applying to graduate programs my freshman year, but as I got further along I realized how cool it is to be able to do research at a university,” Ayala said.

She’s starting a joint PhD program in bioengineering through UC Berkeley and UC San Francisco this fall.

To be fair, Ayala did get to do some pretty cool research. She worked in Professor Joanna McKittrick’s lab her freshman year, and then conducted research for Professor Juan Carlos Lasheras, studying how cells migrate in 3D spaces. For her senior design project, Ayala and her teammates developed an automated blood smear system in collaboration with the UC San Diego Medical School, to make it easier to analyze patients’ blood samples.

Her advice to students?

“There are so many resources available through the IDEA center,” Ayala said. “There’s always scholarship opportunities, events and such a large network of mentorship. It’s this very large network of people there to help you.”

IDEA Scholar: Jose Manuel Rodriguez

Jose Manuel Rodriguez knew he wanted to be an engineer since he was a young boy. He grew up helping his dad fix things around the house, and enjoyed the sense of accomplishment that came with restoring function to cars, doors, sinks etc.

“I always kind of treated school as a game,” Rodriguez said. “I was always trying to get the high scores. I didn’t like seeing anything other than an A. I liked the feeling of doing well in classes. That’s what kind of motivated me.”

A first generation college student, Rodriguez was so motivated to go to and succeed in college that he skipped his senior prom to attend the IDEA Center’s Breakfast with the Dean and learn what the Jacobs School had to offer.

“I said, ‘You know, I’d rather decide about my future than have this one night of fun. I’ll see my friends, they’ll be there. So I went to Breakfast with the Dean and Triton Day rather than go to my high school prom.”

That decision paid off. Rodriguez decided to attend UC San Diego, and is graduating with a degree in mechanical engineering, having worked on jet engines and even helped restore motion to a young boy’s arms.

Rodriguez, who grew up in Fontana, was also a Chancellor’s Scholar. The scholarship funds he was awarded through that program helped relieve a lot of stress about paying for college, and allowed him to get involved in things like the Rocket Propulsion Lab, where he worked to design a biofuel jet engine.

Rodriguez said his senior design project was one of his most memorable projects and learning experiences. He and a team of three other engineering students designed a motorized brace in 10 weeks that would allow a five-year-old who has a rare virus to move his arms for the first time in three years.

“It really didn’t hit me until we were talking to the prosthetist who said ‘You’re making a really big impact in this child’s life,” Rodriguez said. “I feel like it’s really interesting the way engineering is basically the medium between science and society. You’re that medium, trying to make science practical in a way that impacts real life.

As an IDEA Scholar, Rodriguez participated in the Summer Engineering Institute—at that time a five day college preparatory program that has since been extended to a month-- which he said not only helped prepare him for classes, but helped him form a supportive community of friends on campus.

“The IDEA Scholars program really helped me because there were people that come from my background. You relate to them more. And they understand what you’re going though and you understand what they’re going through and the type of struggles they’re having as well. It helps having people to turn to who are like me.”

Rodriguez advises prospective students to not be afraid of asking questions or asking for help.

“One of the troubles I had was asking for help my first year. I’ve always been a person who went through everything alone, never had help from anybody. But then my first year I kind of struggled a bit with classes—not too much but to the point that I was frustrated that everything wasn’t clicking right away. I’d spend time trying to figure things out by myself, and as soon as I made that leap of asking questions to a TA or something-- because that was totally foreign to me, asking questions—that made such a difference. Don’t be afraid to ask questions and be curious about things. Put yourself out there.”

HackXX 2019: code – the future of women in STEM

By Xochitl Rojas-Rocha

Students swing into gear an hour into the hackathon.
Photos by Xochitl Rojas-Rocha
On Saturday, April 6th, young coders from universities across southern California gathered for the third annual HackXX, a 24-hour, women-centric hackathon at the Jacobs School of Engineering at UC San Diego. HackXX has doubled in size each year since its inaugural event in 2017. This year, more than 200 students bundled themselves into the university’s Price Center, clustered around their laptops, and got to work.

Striving for Change

Jiazhen Rong, a fourth-year bioengineering and biotechnology student, said that while no one ever actively discouraged her from pursuing computer science, the way the field was portrayed left her with the impression that coding was “for boys.” That lack of representation took its toll, at least for a while; Rong didn’t explore programming until her junior year in college.

At HackXX, she has sensed none of that former pressure. “I really feel like this event values women,” she said. She and her two teammates, Haihao Sun and Sid Limaye, created an application that allows the user to combine an original photo file with a famous art piece for a fun, new image. Their idea, they said, was to build on what Snapchat achieves with simple filters.

Rong’s teammates, Sun and Limaye, were two of many young men who participated in the hackathon. The event is open to students of all gender identities, backgrounds and disciplines. Attendees traveled from multiple universities throughout California, some with project ideas and teams, some without. The only requirement was that they treat their fellow coders with respect.

“The goal of TESC is to empower engineering students to grow and succeed throughout their college lives and careers. We constantly seek new opportunities and ways to achieve that goal, and celebrating womxn in STEM at HackXX fits perfectly with our mission,” said Colin Feeney, president of UC San Diego’s Triton Engineering Student Council (TESC). TESC hosted the 2019 HackXX.

C: \>code -- The History and Future of Women in STEM

Students present their project, "Safehouse," to the judges.
After what was literally a sleepless night for some, the hackers had their projects judged according to general performance and presentation. In first place were cognitive science freshman Yana Pyryalina (UC San Diego) and computer science senior Sara Kazemi (CSU Monterey Bay), with a project called “The Callout.” The two coders designed a virtual reality simulation to train and prepare women to respond to misogynistic microaggressions in the work place. In one simulation, a male supervisor encouraged the viewer to “wear [her] hair down” and “wear something tight” for an upcoming meeting with potential investors. The simulation then offered the viewer a series of responses, all focused on drawing the supervisor’s attention to how his comments made his employee feel.

In second place, a team of coders created a role-playing game called “Maze Rescue.” With cute, Undertale-esque graphics, the game challenges the player to save their friend, a female researcher who has been kidnapped, along with her work, by a mad scientist. The player must solve a maze filled with trivia questions on notable women in STEM to save their friend.

The third place winner was “Safehouse,” an application that sends out a call for assistance when a woman feels like she’s in an unsafe situation. The application is volunteer-based, with the team sending out requests for people to sign their homes or apartments up as “safehouses” where a woman can take shelter until help arrives. The team was inspired by UC San Diego’s safety escort system, which calls a Community Service Officer (CSO) to a student’s location from sunset to 4:00 a.m. daily if they feel unsafe.

HackXX sponsor Northrop Grumman challenged students to find a
way to program a small robot car and successfully remove a hair tie
 from its stand without knocking the stand over, and transport
it through a maze.
While not every team placed, others did reach the final round of judging or took home awards from HackXX sponsors such as Northrop Grumman and iTradeNetwork. One such team won “Best Women in Hack” for devising an application that helps pregnant women identify foods that they can eat, and assists them in planning meals in advance. Another finalist team created a virtual reality simulation of a women’s history museum. By using the virtual reality headset to interact with different exhibits, a visitor can travel to the moon to learn about Sally Ride, the first American woman in space, or transport to the cockpit of aviator Amelia Earhart to listen to a recording describing her life and achievements.

For HackXX co-directors Alice Lee, a fourth-year cognitive science student, and Bilguun Bulgan, a graduating computer science student, that moment was more than half a year in the making.

“It’s been really rewarding to see everything come to life, and to see how involved all of our team members are,” said Lee. Some students, she said, see hackathons as just a way to connect with corporations and find a job. With HackXX, it’s different. “Everyone on this team actually cares about what HackXX stands for, and I thought that was really cool.”

Student-run research symposium draws big crowd

By Kritin Karkare

 research. Photos courtesy of Lab Expo. 

The UC San Diego Biomedical Engineering Society hosted its seventh annual Lab Expo in January, drawing upwards of 800 attendees and featuring research from more than 60 labs from a variety of disciplines across campus, including anthropology, electrical and computer engineering, bioengineering and more.

Lab Expo chairs and bioengineering students Daibo Zhang and Jessica Ma spent eight months planning the all-day student-run research symposium meant to develop scientific literacy, promote interdisciplinary collaboration and encourage scientific advocacy.

Keynote speaker Grant Sanderson.
Keynote speaker Grant Sanderson, a math educational Youtuber with 1.6 million subscribers, drew a large crowd while talking about his approach to communicating math more clearly. Sanderson, better known by his Youtube channel’s name, 3Blue1Brown, developed his own mathematics visualization programming library to help viewers get a more intuitive grasp on abstract math concepts like neural networks and the Fourier Transform. He thinks that his visualization-first approach has merit.

“By focusing on clarity of communication, it makes you think more clearly about what it is you’re doing,” Sanderson said. “Whatever piece it might be, if you think about how you present this to an audience, it will shape your own understanding of the context, rather than letting communication be an afterthought.”
A research poster presentation and the keynote speech were just the tip of the iceberg. What better way to practice communicating science than to have graduate students pitch their research in only five minutes?

The second annual Lab Expo Graduate Showdown (LEGS) featured seven students from different departments including cognitive science and mechanical and aerospace engineering, competing to best condense and communicate their research projects.

Only one could come out on top: judges picked Andrew Shibata, a first year cognitive science graduate student, as the winner. Based on his experiences listening to the myriad accents and voices in California, Shibata’s research aims to develop a database of voices characterizing the San Diego region, and study how people’s voices change the longer they live in San Diego.

Next up, the Biomedical Engineering Society is hosting their annual Translational Medicine Day on March 6. This event aims to bring together the research and healthcare communities-- including students, faculty and industry-- to bridge the gap between bench and bedside.

Jackie Villalobos: UC Engineer

Jackie Villalobos, a fourth year electrical engineering student at UC San Diego, has some advice for future engineering students: get involved on campus! She learned this the hard way.

“My first year, I wasn’t involved in anything at all,” she said. “I came in and thought I’m just going to get on top of studying and get used to school. That was the worst decision I could have made and I really regret it.”

It’s hard to image that, since Villalobos is now the president of the Society of Women Engineers (SWE) at UC San Diego, helped found the Anita Borg Leadership and Engagement (ABLE) outreach program, is a student worker organizing educational camps at the San Diego Supercomputer Center, and is an undergraduate researcher in Professor Tara Javidi’s lab.

“I met so many new friends through SWE and I felt so much more supported than when I was alone trying to figure out college by myself,” Villalobos said. “You just have to take that first step. If you’re just going to class and going home, there’s not much growth that will happen because you’re not getting out of your comfort zone.”

Villalobos grew up in Chula Vista, twenty miles south of UC San Diego. Her mother and father—who is also an electrical engineer-- immigrated to the United States from Mexico for her father’s job before she was born. The engineering mentality that she saw in her father convinced her that this was a field she was interested in.

“What appealed to me about engineering is if something would break around the house, or the garage stopped working, he would never call anyone to come fix it-- he’d be the one to fix it, and he’d ask if I wanted to help. That’s what got me into engineering, was seeing how applicable it was to everything. That if anything broke, he’d say ‘Oh I can fix it.’ I really liked that mindset and that’s what appealed to me with engineering.”

Her decision to choose electrical engineering for her major wasn’t so decisive. That’s why she enjoys devoting time to outreach efforts that help high school students learn more about what specific majors entail.

“I ended up really liking electrical engineering, but going in I know I didn’t know what I was getting into. That’s why now through SWE, outreach is my favorite part of what we do because we’re able to talk to high school girls about what we do in our majors, what goes on in our classes, and they can explore different majors.”

In addition to her role with SWE, Villalobos is an undergraduate researcher in Javidi’s electrical engineering lab, working on path optimization for drones. The goal is to be able to give a drone a starting point and end point, and have it figure out the most optimized travel path. Their current application is for farmers who use drones to check on their livestock and crops—instead of the drone finding the target object and then landing, the team is working to be able to dispatch the drone, have it check on the object of interest, and then return to its home destination, all on its own.

In addition to finding a group or community to get involved with, Villalobos has one other piece of advice for current and future engineering students: find time for yourself.

“That’s something I always try to work on, because you have a lot of things in your day but there’s also a time where you need to breathe and relax and take a step back,” she said. “Take a moment. I would say for me at least it was about not going for everything all at once and piling a bunch of stuff on. Little by little you take steps, but you just have to make that first one.”

Rebecca Kandell: Sloan Scholar

Rebecca Kandell knew she wanted to work in a STEM field from a young age. Her mom was a first-generation college student and electrical engineer, and her dad studied mechanical engineering, so engineering had always appealed to her. But she also was interested in biology and had dreams of becoming a medical physician in her youth. It wasn’t until applying for college that she realized she could meld the two into one field: bioengineering.

“I grew up in a family of engineering and science,” Kandell said. “I knew I wanted to get into a technical field.  When I attended a high school outreach event and learned about biomedical engineering, I thought that was a great way to combine engineering and biology.”

Kandell, who grew up in Ridgecrest, California, is now pursuing a Ph.D. in bioengineering at UC San Diego as a Sloan Scholar. Sloan Scholars receive a four-year fellowship worth $40,000 to stimulate fundamental research by early career scientists of outstanding promise.

She’s working in the lab of Ester Kwon, a professor of bioengineering at UC San Diego, designing nanoparticles with an emphasis on treating traumatic brain injury (TBI). Her research focuses on brain and nanoparticle therapy, working to develop tiny sub-cellular particles that could be used to more effectively transport drugs to the brain and help treat TBI and other neurodegenerative diseases. The carried drugs can help with treating complications that come with TBI such as brain swelling and cell death.

Kandell earned both her bachelor’s and master’s degrees in biomedical engineering at California Polytechnic State University and conducted research while working towards her degrees. There, she used bioimaging and cell culture to investigate natural therapies to prevent the damaging effects of ultraviolet radiation (UV) on skin cells.

While at Cal Poly, Kandell also held several officer positions with the Society of Women Engineers (SWE).  As president of SWE, one of the largest clubs on campus, she spearheaded multiple large-scale outreach events attended by thousands of K-12 students, and visited local schools to teach engineering principles to underrepresented minority students.  With her outreach and volunteering, Kandell hopes to inspire students to study engineering in college and reach their full potential.  She has continued to volunteer in San Diego by mentoring students in the Jacobs Undergraduate Mentorship Program (JUMP).

“I value mentoring students, both through scientific research and outreach programs like JUMP,” she said. “Mentorship provides a support system among students so that knowledge and positive experiences can be shared. I am committed to encouraging others to achieve their educational goals.”
Kandell is considering her research career goals, but said there are two components she knows her future endeavors will involve: research and mentorship.

“I am incredibly grateful to the Sloan foundation for their generous award which will allow me to conduct research and also give back to the community.”

Seeing at a different scale

When he was in high school and building robots, Marquez Balingit couldn't help but wonder: How do these parts work and how do circuits communicate with each other?

He realized is questions could be answered in one word: nanoengineering. So when it came time to pick a college major, that's what he chose. He wanted to understand what things at the nanoscale or submicron level look like.

Now an undergraduate the Jacobs School, Balingit tackles this question at the Nano3 lab. In the future, Balingit sees himself creating a nonprofit company specializing in a form of energy conversion, battery or generator that is efficient in every aspect: cost, power conversion and practicality. He hopes that it can be free and practical for developing countries, giving them more autonomy so that they can power themselves.

Balingit says he is inspired by the works of Nikola Tesla. From his perspective, Tesla's main desire was to create free energy by harnessing and manipulating existing energy on earth and within the air so that everyone can access it.

Balingit teaches  users unfamiliar with the scanning electron microscope, or SEM, how to use it independently. Unlike regular optical microscopes, SEM does not use photons. Instead, it uses electrons, which allows the device to capture smaller features at the 1 micron scale, approximately ⅕ the size of a human red blood cell.

"I like the idea of being the bridge of information by gathering some knowledge, filtering out the details and explaining it to someone clearly," Balingit said. "I learn how to use high tech equipment and understand the standard operating procedures to be able to articulate that to other people so that they can use it on their own."

Outside of training users, Balingit also works on service measurements of sample materials, in order to to figure out the features that users want. He says he feels challenged to get a clear, high resolution images and excited to see something he's never seen before.

"Sometimes things I see in textbooks, I end up actually imaging which is pretty amazing because I never thought I'd be able to. In my textbooks, a lot of things are in the 10 microns and 5 microns and I wondered how they even get these images. Now, years later, I'm getting images that are roughly similar to that," Balingit said.

The Nano3 lab is also looking to increase outreach with the SEM by remotely connecting with high schools and community colleges to show them the SEM's  full capabilities of the and what it can provide from an educational standpoint. Balingit feels like this will help bridge the gap between college and high school curricula in nanotechnology by bringing this information to them. By magnifying everyday objects like pennies and ballpoint pens, Balingit also hopes that using SEM will inspire young students to pursue an  education/career in a STEM field.

Eddie Tapia: Graduate Road Map founder

Eddie Tapia is a UC San Diego mathematics- computer science alumnus currently working on dual master’s degrees in electrical and computer engineering and technology ventures at Carnegie Mellon University. When he was president of the Society of Hispanic Professional Engineers (SHPE) at UC San Diego, he created the Graduate Road Map (GRM) event to increase the number of underrepresented students applying to graduate school. Here’s why:

“I grew up in a low-income household, so my goal for the longest time was to go work after my bachelor’s degree so I could help provide for my family. As a result, grad school was not in my plans throughout most of my undergraduate career. Yet, through the help of some amazing friends, staff members, and faculty, I learned about the benefits of obtaining an advanced degree and they provided me with the insight I needed to craft a strong application. 

However, not everyone is lucky enough to have the help I had and I noticed that many students, especially underrepresented minorities, were not applying to graduate school because they had a lot of misconceptions about the whole process. I was bothered by this realization so I began to think of ways where I could give students the opportunity to connect with faculty, current graduate students, and university representatives to demystify the graduate school application process. I created GRM to increase the number of underrepresented students applying to graduate school and support students who might otherwise not apply to graduate school.”

This year, SHPE will host GRM on February 9. If you’re not sure if graduate school is a good fit for you, or don’t really know what the application process is like, come learn from the experiences of current graduate students and professors. Thanks to SHPE, the National Society of Black Engineers and the Society of Women Engineers at UC San Diego for organizing this event. Details here:

ARMOR Lab Soft Robotics

Han-Joo Lee, a graduate student in Professor Kenneth Loh's ARMOR Lab, is working on a new way to make soft robots move. The method he's developing uses ultrasonic atomization — similar to how humidifiers work— to get soft, biomimetic tissues to expand and move. The research was published in Soft Materials and Structures on January 19.

Lee's talk about this research at Lab Expo 2019's Graduate Showcase won 2nd place from the judges panel, and third place in the popular vote.
