J.S. Chen elected as the President of Engineering Mechanics Institute (EMI) of ASCE

J. S. Chen, William Prager Professor of Structural Engineering Department and Director of Center for Extreme Events Research at the UC San Diego Jacob School of Engineering, has been elected as the President of Engineering Mechanics Institute (EMI) of the American Society of Civil Engineers (ASCE) effective October 1, 2015. 

The missions of EMI are to serve the engineering community through the development and application of engineering mechanics by anticipating and adapting to new challenges that will face tomorrow's engineers; to create an environment that facilitates professional growth to ensure that these future challenges will be met; to establish a presence at the forefront of new thrusts of mechanics by promoting the most innovative developments in the field, regardless of the discipline of the ultimate user; to provide a home not only for those involved in the traditional disciplines, but also for those involved with emerging areas of mechanics; and to promote the interdependence of engineering mechanics and other disciplines by providing an interdisciplinary forum for researchers, practicing engineers, industry representatives, citizen groups, public officials and others.

 Center for Extreme Events Research

The Center for Extreme Events Research at UC San Diego has been established to offer solutions to a wide range of challenges associated with extreme events based on the most advanced computational and experimental technologies. Challenges we address are:


Our advanced research programs support predictive as well as retrofit strategies to make critical infrastructures blast resistant and capable of withstanding man-made and natural disasters. Expertise includes simulation-based assessment of residual strength and structural failure estimation after disastrous events.


We provide rapid assessment of damage after disastrous events using simplified and reduced-order computational and experimental techniques with the aid of available sensor data and visualization information. We also provide solutions for mitigation and retrofitting damaged infrastructure.


We work to prevent or mitigate brain and body injury due to bomb blasts, car crashes and collisions on the football field. This is of great importance to the military as well as civilian sectors. The state of the art computational capabilities at the Center for Extreme Events Research allow a thorough understanding of the mechanisms behind injury and provide guidance for design optimization for injury prevention.
