Portrait of Jaeseok Byun

I am a research scientist working towards developing practical AI algorithms in resource-constrained systems. I received my Ph.D. in Electrical and Computer Engineering from Seoul National University, advised by Taesup Moon, with the Outstanding Dissertation Award. In Fall 2026, I will join the Agentic AI team at Amazon Web Services (AWS) in New York as an (Incoming) Applied Scientist. During my Ph.D., I worked as a research intern at Amazon AGI and Microsoft Research Asia, and as a visiting student researcher at Stanford University. My primary research focus lies in image denoising, multi-modal representation learning, and agentic AI.
