About

I’m a system software engineer at MangoBoost. I received my Ph.D. in Artificial Intelligence from Ajou University, where I focused on computer systems in the Computer Systems Laboratory (CSL) under Prof. Jeongseob Ahn.
Currently, I’m diving deep into improving storage performance over high‑speed network environments (NVMe‑oF) using data‑processing units (DPUs). In the past, my research interests included efficient memory management for emerging hardware and heterogeneous memory systems involving CXL interconnects and non‑volatile memory.
Here are my CV, Github profile, and Google Scholar.
