About me

I have been with the Electrical Engineering Department at Princeton University, as a Postdoctoral Research Associate in the research group of Prof. H. Vincent Poor, since October 2017. Before that, I received my PhD degree in Electrical Engineering from the University of Maryland College Park in August 2017, under the supervision of Prof. Sennur Ulukus. My PhD thesis won the Department of Electrical and Computer Engineering's annual Distinguished Dissertation award in 2017.

My research focuses on developing fundamental solutions for latency and security issues in current and emerging applications in communications and control. I use mathematical tools drawn from optimization, wireless communications and information theory to develop such solutions, with the applications spanning the internet of things (IoT), cyber-physical systems (CPSs), next generation cellular systems and light fidelity (LiFi).

I am currently in the academic job market, looking for tenure-track faculty positions.
