About Me
I am a Postdoctoral Researcher in the Department of Electrical Engineering at Princeton University working under the supervision of Professor H. Vincent Poor.
In 2018 I was a Lecturer in the Department of Operations Research & Financial Engineering at Princeton University.
I received my Ph.D. from the Department of Electrical and Computer Engineering at University of Illinois at Chicago (UIC). I was lucky to have Professor Daniela Tuninetti and Professor Natasha Devroye as my advisors.
Research Interests
