Introduction

I am an Assistant Professor in Electrical Engineering and an associate faculty at the School of AI and Data Engineering, IIT Ropar. I lead the Integrated System Design Lab (ISDL), focusing on analog, mixed-signal, and RF IC design for computing and sensing. I am a senior IEEE member and part of the AMS/RF committee of the DevSET program. Prior to joining academia, I worked at the GE Technology Centre (2010-12) and the R&D division of Siemens (2017-18). I am an avid reader.
