He has joined Dept. of Electrical Engineering in 2010. He has authored/ co-authored 50+ journal, 90+ conference and 25+ patents (applied/granted). His research interests are in semiconductor device physics and processing technologies for advanced memory, computing, and neuromorphic systems. He likes to experiment with teaching/learning methods like "Think-Pair-Share". He has contributed to the TIFAC National Vision for ICT 2035. He works to augment national semiconductor manufacturing capability at Semi-Conductor Labs, Chandigarh, for which he has won the Dr. PK Patwardhan Technology Development Award 2018.

IIT Bombay Campus Service

Professional maintenance and tracking in a critical need for Indian Govt. institutions. We have established an online campus maintenance tracking system that was initiated in 2012 at the lab level, demonstrated at various levels including institute wide AC maintenance till 2015 in a voluntary mode. This shows the commitment of campus service groups to improve services. From 2015 it is now officially constituted / recognized as part of the IITB administration.
