I'm an Assistant Professor of Computer Science at Duke University. Before joining Duke in Fall 2021, I was a Postdoctoral Researcher in the VMware Research Group; since then, I've continued my collaborations with VMware as an Affiliated Researcher. I received my PhD in Computer Science from University of Maryland, advised by Bobby Bhattacharjee.

I enjoy working broadly at the intersection of systems, networking, and security. My current research focuses on two directions: 1) introducing new abstractions and tools for building (and reasoning about) secure, trustworthy software systems, 2) building systems that improve performance for modern networking and machine learning applications. While those are my main directions, I have other ongoing projects that range from network performance measurement to security threat analytics.

I'm always looking for interested students. Look here for how to get in touch with me.
