Pankaj Sagar, PhD

I did my doctoral degree from the Department of Instrumentation and Applied Physics (IAP) on cryogenics Instrumentation from the Indian Institute of Science (IISc) and thereafter did my post doctoral studies from Centre for Cryogenic Technology (CCT), IISc Bengaluru, and later from University of Twente, Netherlands. I Have published over 20 articles in reputed International Journals and Conferences. I have been awarded both the SIRE-Fellowship for international research by DST (SERB) as well as the Young Scientist Research award (YSRA) given by the Board of Research in Nuclear Science (BRNS-DAE). My broad research area includes the design and development of cryogenic sensors for space applications, Developing techniques for Non-destructive evaluation of SRF cavities, Designing cryostat and cryo-compatible systems.
