I am an assistant professor of computer science at the University of Texas at Austin. I co-lead the UT Networked Systems Research Group and am also a member of the Wireless Networking and Communications Group and 6G@UT.

My research focuses on networked systems, distributed systems, and operating systems. I build new hardware and software systems that make cloud and edge datacenters faster, more efficient, and more resilient.

Prior to joining UT Austin, I was a senior researcher in the Office of the CTO in the Azure for Operators group and at Microsoft Research Redmond. I received my PhD from the Computer Science Department at Carnegie Mellon University, where I was advised by Vyas Sekar and Srinivasan Seshan. My dissertation introduced new abstractions and runtime systems to enable elastic and resilient in-network computing. My work was supported in part by the Microsoft Research PhD Fellowship. Prior to joining CMU, I worked as a research scientist at KAIST. Before that, I received a BS and MS degrees in Computer Science and Engineering from POSTECH, South Korea.
