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. 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.
My research interests lie at the intersection of systems and networking, with a focus on building software systems that improve the performance, efficiency, and resilience of data- and network-intensive applications running on emerging programmable infrastructures (e.g., programmable switches, NICs, and xPUs). I have also worked on various topics in security and wireless systems.
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.
