Open Positions at Systems Security Lab (SSLab)

I am looking for passionate students who are insterested in doing research in systems security and possibly other fields in security. The one most important qualification that I want from you is that you inherently enjoy hacking and fixing stuff. Don't hesitate to send me an email if you are interested :) Currently, I have the following positions open:

  • Undergraduate Research Internship (학부연구생)
  • Masters Students
  • Doctoral Students

About Me

I am currently an assistant professor at Dept. of Computer Science and Engineering at Sungkyunkwan University since September 2019. Prior to my current position, I spent one year as a postdoctoral researcher at CISPA under the supervision of Prof. Michael Backes. I received my Ph.D. from KAIST in 2018, advised by Prof. Brent Byunghoon Kang, and B.S. from The University of Texas at Austin.

My main research interests lie in retrofitting security in computing systems against today’s advanced threats. My research interests include but are not limited to Operating System Security, Trusted Execution Environments, Program Analysis, Software Security, and Secure AI Computation in Cloud.
