My research interests focus on semiconductor device physics and modeling for RF, power, and emerging electronic applications. I received my Ph.D. in Electrical and Computer Engineering from the University of Illinois Urbana-Champaign in 2022, where I was advised by Prof. Shaloo Rakheja. Before joining ASU, I was a Postdoctoral Fellow at Columbia University, hosted by Prof. Harish Krishnaswamy.

I am looking for motivated Ph.D. and M.S. students, postdoctoral scholars, and undergraduate researchers. If you are interested, please email me with a copy of your CV to start a conversation.
