BRIEF BIO
|
I did my doctoral degree from the Department of Instrumentation and Applied Physics (IAP) on cryogenics Instrumentation from the Indian Institute of Science (IISc) an there after did my post doctoral studies from Centre for Cryogenic Technology (CCT), IISc Bengaluru, and later from University of Twente, Netherlands. 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.
