  Now a PhD student at UMD

I am an Assistant Professor of Computer Science at Oregon State University.
I work at the intersection of computer security, privacy and machine learning.

Research Interests

I am an AI hacker working on building trustworthy and socially-responsible AI-enabled systems so that humans use those systems to improve our lives and society in the future. Thus far, I’ve been interested in characterizing the security/privacy and dependability issues of AI-enabled systems from a holistic view (i.e., systems security perspective). I received the Google Faculty Research Award 2023 and the Samsung Global Research (GRO) Award 2022. I am selected as a DARPA Riser (2022) and was invited as a speaker at USENIX Enigma (2021).

Please drop me an email with your CV if you're interested in working with me.

Bio

I earned my Ph.D. from the University of Maryland, College Park, under the supervision of Prof. Tudor Dumitras in 2021. I received my bachelor's degree from Seoul National University in 2015. I was fortunate to spend a winter at Google Brain in 2021 (working with Dr. Nicholas Carlini and Dr. Alexey Kurakin) and to spend 6-months at Frame.io in 2017 (working with Dr. Abhinav Srivastava).
