I am currently a Postdoctoral Researcher in HPArch Group at Georgia Institute of Technology (Georgia Tech) supervised by Prof. Hyesoon Kim. Prior to Georgia tech, I received a Ph.D in School of Computing from KAIST (2023), advised by Prof. Jaehyuk Huh.
My research interests lie in GPU architecture, trusted computing, heterogeneous systems, distributed computing, and systems for machine learning. During my Ph.D. studies, I focused on building secure architecture to provide a trusted execution environment(TEE) on accelerators such as GPUs, and NPUs with low-performance overhead. Currently, I am actively engaged in extending my research field to address various challenges in the Processing in Memory (PIM) and High-Performance Computing (HPC) systems.
