About me
I am an Associate Professor of ECE at UNC Charlotte. I have been with UNC as a tenure-track Assistant Professor since August 2019. Before that, I spent two wonderful years at Princeton's EE as a Postdoctoral Research Associate, hosted by Vince Poor. In 2017, I was fortunate to receive my PhD degree in EE under the supervision of Sennur Ulukus at the University of Maryland's ECE. I received the NSF CAREER Award in 2022.
My research interests are in communication and information theory, communication networks, wireless, signal processing and machine learning. Recently, I have been working on projects pertaining to
federated and distributed learning
semantic communications (see, e.g, age-of-information)
information-theoretic security and privacy
