I work in the area of Structural Engineering. This page contains my professional bio and will guide you through my work. My research efforts are geared towards multi-hazard protection of critical infrastructure from extreme events such as earthquake, blast and impact. As part of my multi-disciplinary research efforts, I develop analytical models, perform numerical analysis, and conduct experiments. My aim is to develop to develop simplified analysis and design guidelines to help professional design community to use these methods.
I have uploaded some of my research work to this website which might be useful to people with similar interest in Structural Dynamics and Earthquake Engineering. Currently, I maintain pages on these areas, you can explore them further:
