Active researcher with over forty-five years of experience in nuclear reactor engineering with specific involvement in finite element code development for coupled fluid-structure-thermal interaction problems for nuclear reactor safety and structural integrity issues, experimental stress analysis, nuclear containment structural and thermal hydraulics safety studies, impact and high strain rate problems for soft and hard missiles and wave propagation studies in solid and fluid media. Containment integrity assessment, hydrogen transport and combustion studies, passive hydrogen recombiner development and hydrogen deflagration and detonation assessment, aerosol transport and tsunami evaluation of Indian coastal nuclear facilities and development of severe accident management guidelines for Indian nuclear facilities. Supervised a team of ninety nuclear engineers for structural mechanics, thermal hydraulics, reliability and safety evaluation of nuclear reactors for design/beyond design basis accidents for external and internal extreme events. Guided Ph D & M Tech students at IITs / IISc and Homi Bhabha National Institute. Served as Chairman of International Scientific Committee for 21st International Conference on Structural Mechanics in Reactor Technology and guest editor of the Special Issue of Nuclear Engineering and Design. Organized international and national conferences and successfully coordinated standard problem and round robin exercises on concurrent computational mechanics / experimental studies related to reactor safety problems.
