Junho Kim (Ph.D. Candidate)

Biography

• I am a Ph.D. candidate in the Department of Information Security, School of Cybersecurity, at Korea University. I am also a researcher at the Digital Forensics Research Center, Institute of Cyber Security & Privacy, Korea University.

• My research interests span a wide range of areas within digital forensics, including digital forensics, multimedia forensics, database forensics, mobile forensics, AI-driven forensic analysis, document forensics, RAID analysis, and filesystem analysis. I am particularly passionate about exploring and analyzing unknown or unconventional data sources.

• I received my B.S. in Computer Engineering from Kangnam University in 2011 and my M.S. in Information Security from Korea University in 2020. I am currently pursuing my Ph.D. in Information Security, which I expect to complete in 2026.
