His research interests are earthquake safety assessment and retrofitting of buildings. He has developed the Applied Element Method (AEM) to solve crack initiation and propagation in near-fault rupture phenomenon and reduced computation time. He has extended this method to study collapse behavior of structures subjected to blast loading.
Launched at IIITH, the M.Tech and Ph.D programs in Structural Engineering in 2002. Established Earthquake Engineering Research Centre, one of its kind in India, working for solutions to India specific problems. He has supervised 10 Ph.D. and 16 M.S. students, and presently supervising 10 PhD students. He has published ~120 papers in national and international journals.
