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. My research interests includes efficient memory management for emerging hardware and heterogeneous memory systems involving NUMA, PMEM, CXL and RDMA.
Currently, I am developing system software H/W acceleration using DPUs.
