Hi! I am Jaeho Jeon (전재호, 田宰昊), a Ph.D. student at DGIST (Daegu Gyeongbuk Institute of Science and Technology), advised by Prof. Young-Sik Kim in the PACL lab. My research focuses on side-channel analysis.

My goal is to become a uniquely recognized expert in side-channel analysis, so that anyone in Korea who needs side-channel analysis naturally turns to me or the PACL lab. Building on side-channel analysis as my core, I plan to gradually expand my research into computer architecture, quantum computing, networking, and coding theory.
