Introduction

I am an assistant professor in the Department of Electrical Engineering and an associate faculty member at the newly constituted School of Artificial Intelligence and Data Engineering at IIT Ropar. My teaching and research interests include Analog, Mixed-Signal and RF integrated circuit design, neuromorphic electronics, AI oriented circuits and systems and sensors interfacing circuits. I am a senior member of IEEE and an active reviewer for many reputed journals. Additionally, I am the PhD coordinator for the Microelectronics and VLSI Design group and serve on the institute's Ranking Committee. I direct the Integrated System Design Lab (ISDL) at IIT Ropar. We do cutting-edge research on Integrated Circuit Design for applications in computing and sensing. Our research outcomes are well documented in various patents, reputed journal publications and conference proceedings. Our research is funded by research sponsors such as the Science and Engineering Research Board (SERB), the Ministry of Electronics and Information Technology (MeitY) of the Government of India and generous support from IIT Ropar. We strongly collaborate with the Semi-Conductor Laboratory (SCL), Mohali. My team members are highly passionate about technology and are self-motivated. Each day, we strive to achieve excellence through hard work, grit and perseverance. I am always looking for highly motivated candidates interested in developing skills in Integrated Circuit Design for PhD or PG/UG capstone project.
