Welcome

I am an Assistant Professor at the University of Texas at Arlington (UTA). My research interests span operating systems, systems virtualization, file and storage systems, computer networks, and systems performance optimization, especially in the context of cloud computing. Before joining UTA, I was an Assistant Professor at the State University of New York (SUNY) at Binghamton. I received my Ph.D. degree from Purdue University, where I researched in FRIENDS Lab under the direction of Professor Dongyan Xu.

I am the recipient of an NSF CAREER Award (2023).
