I am a Senior Researcher at Microsoft in the Office of CTO at Azure for Operators where I build software systems that make next-generation cellular network infrastructure secure, reliable, and energy efficient. I completed my PhD in the Computer Science Department at Carnegie Mellon University, advised by Vyas Sekar and Srinivasan Seshan. My work was supported by Microsoft Research PhD Fellowship. Prior to CMU, I worked at KAIST as a research scientist. Before then, I received a BS and MS degree in Computer Science and Engineering from POSTECH, South Korea.
My research interests lie in the intersection of systems and networking with a focus on building software systems that improve the performance, efficiency, and resiliency of data- and network-intensive applications running on emerging programmable infrastructure (e.g., programmable switches, NICs, and xPUs). I also worked on various topics in systems security and wireless systems.
