Hello!

I am currently a Postdoctoral Associate at Duke University, where I am fortunate to work with Prof. Robert Calderbank. I received my PhD in Electrical & Computer Engineering in December 2024 from Rice University, where I was fortunate to be advised by Prof. Ashutosh Sabharwal. I also received my MS in ECE from Rice in December 2020 under Prof. Sabharwal’s supervision. Prior to joining Rice for graduate school, I received my B.Tech. in Electronics & Electrical Communication Engineering from IIT Kharagpur in July 2018.

My research interests are in next-generation (6G) wireless systems (specifically joint sensing and communication) and radar imaging. I employ a multi-faceted approach spanning theoretical analysis, algorithm design, and experimental demonstrations in my research. For more details, head over to my Research page.
