I am an Assistant Professor at the Rutgers University's CS department. I work on Operating Systems (OS) for large-scale datacenter and mobile systems and their implications on Computer Architecture, Distributed Systems, and High-performance Computing systems. More specifically, we are building systems for efficiently managing memory and storage heterogeneity.

Rutgers Systems Research Lab

We are hiring PhD students and Interns to join my group at Rutgers! If you are a PhD, Masters, or Undergraduate student interested in fundamental Operating Systems, Computer Architecture, or distributed systems research, write me an email with your CV (or GitHub repo) or stop by my office!
