Research

Systems Security Lab's mission is to retrofit the security architecture of modern computing systems against the constantly evolving threats and broadening attack surface. Today's computing systems are increasingly more complex while the attackers and their strategy constantly evolve. SSLab's research focuses on discovering weaknesses in existing defenses and proposing novel principles for defense to stay ahead of the curve.

Hojoon Lee Associate Professor

Prof. Hojoon Lee is an associate professor in the Department of Computer Science and Engineering at Sungkyunkwan University since September 2019. Prior to his current position, he spent one year as a postdoctoral researcher at CISPA under the supervision of Prof. Michael Backes. He received his Ph.D. from KAIST in 2018, advised by Prof. Brent Byunghoon Kang, and his B.S. from The University of Texas at Austin. His main research interests lie in retrofitting security in computing systems against today’s advanced threats, including operating system security, trusted execution environments, program analysis, software security, and secure computation in the cloud.
