Prof. Prabhakar V. Varde is a mechanical engineer by education, nuclear engineer by profession and an expert in the area of probabilistic risk assessment and its application as part of risk-based engineering. He started his career at the Bhabha Atomic Research Centre in 1983 as nuclear engineering trainee of BARC Training School. After completion of training, he 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 Associate Director, Reactor Group. During his service, he completed his Ph.D. from Indian Institute of Technology (IIT) Bombay in 1996 and later focussed his research in nuclear safety in general and risk-based engineering, in particular, along with reactor-related services responsibilities. He also served as Senior Professor and Member of the Board of Studies in Engineering Sciences of Homi Bhabha NationalInstitute, Mumbai. He did his postdoctoral research at Korea Atomic Energy Research Institute, in 2002-2003. He is a visiting professor at Center of Advanced Life Cycle Engineering, University of Maryland, USA. He is also honorary professor at Amity Institute of Nuclear Science & Technology, Amity University, India. He has over 250 research publications at national and international level. He has co-authored/edited more than 17 books and proceedings. In recent times he received Homi Bhabha Group Achievement Awards in 2017 for 'Design and Development and Commissioning of Apsara reactor' as a team member and in 2018 as team leader for 'Development and Implementing Dhruva Nuclear Reactor Simulator', respectively. He founded the Society of Reliability and Safety (SRESA) in 2010. He is also serving as President, Society for Reliability and Safety, India. He has also been serving as lead Chief-Editor for SRESA Int. Journal of Life Cycle Engineering published by Springer.
