I am a Visiting Associate and a former Assistant Professor of Structural Engineering (Division of Engineering and Applied Science) and Geophysics (Division of Geological and Planetary Sciences) at Caltech (currently on a Fulbright Academic and Professional Excellence Award to India). My research interests include earthquake engineering, computational mechanics, structural dynamics, and computational seismology. My research group is currently working on various aspects of rupture-to-rafters simulations of earthquakes and building response using high-performance computing. I offer seismic expert consulting services through QuakeRisk Inc. You can follow my earthquake blog, QuakeBlog to get the latest info on earthquakes.

SPECFEM3D: A parallel program executable on a computer cluster, based on the Spectral Element Method. It can simulate an earthquake and model the propagation of seismic waves through the earth structure to distant locations and compute the ground motion time-histories at user-defined stations.
FRAME3D: A nonlinear structural analysis program for damage analysis of buildings.
More about me:
I got my Ph.D. in Civil Engineering from Caltech under the guidance of Dr. John F. Hall (Professor of Civil Engineering) who is an expert in computational mechanics and earthquake engineering. My Ph.D. Thesis was on the behavior of tall buildings during strong earthquakes from nearby sources. I developed a three-dimensional nonlinear dynamic structural analysis program, FRAME3D, for this study. I continue to upgrade the program at this time. You can find detailed information about the program along with references at the following web-site: http://www.frame3d.caltech.edu. I have a Bachelor's degree from the Indian Institute of Technology (Senior thesis advisor: Dr. V. Kalyanaraman, Professor (Retired) and Former Dean IC & SR, Indian Institute of Technology, Madras, India) and a Master's degree from Rice University (Thesis advisor: Dr. Joel P. Conte, Professor, University of California, San Diego))
