Dr. C. Senthil Kumar joined the Atomic Energy Regulatory Board (AERB) in 1990 and is presently the of cer-in-charge of the Southern Regional Regulatory Centre of AERB in Chennai. His areas of specialization include reliability engineering, probabilistic safety assessment (PSA), software reliability, seismic safety, statistical analysis, remote sensing and GIS applications. He has performed the reliability analysis of shutdown system, decay heat removal system, power supply system and passive system reliability analysis as part of Level-1 PSA for the Prototype Fast Breeder Reactor which is under construction at Kalpakkam. His contribution in the seismic re-evaluation of Fast Breeder Test Reactor earned him the AERB group achievement award. His current research is in the development of a methodology for performing multi-unit PSA at Indian nuclear sites. He is also a member of AERB's regulatory review committee on PSA for nuclear facilities. He has earned the Erasmus-Mundus EURECA fellowship for post-doctoral research in the area of 'Software reliability for computer-based systems in safety critical operations' at Sweden in 2009-2010.

Dr. Prabhakar V. Varde is a mechanical engineer by education, a nuclear engineer by profession and awell-known expert in the area of probabilistic risk assessment and its application as part of risk-based engineering. He started his carrier at Bhabha Atomic Research Centre in 1983 as nuclear engineering trainee of BARC Training School and after completion of training joined erstwhile Reactor Operations and Maintenance Group now Reactor Group, served as operations engineering for Dhruva-a 100 MW research reactor at BARC and rose through the administrative ladder and retired in 2019 as an associated director, Reactor Group. During his service, he completed his Ph.D. from Indian Institute of Technology (IIT) Bombay in 1996 and later focused his research in nuclear safety in general and risk-based engineering in particular, along with reactor related services responsibilities.
