Short Bio

My research interest focuses on designing safe and secure learning-enabled autonomous systems by understanding from theory to implementation.

I’m exicted to join Prof. Taesoo Kim’s group at GaTech as a postdoc researcher. Previously, I obtained a PhD degree in Computer and Information Science from University of Pennsylvania, where I was fortunate to work with Prof. Insup Lee and Prof. Osbert Bastani. I received a Bachelor’s degree in Computer Science from Seoul National University in 2010 under the mentorship of Prof. Byoung-Tak Zhang and Prof. Jehee Lee. I continued my graduate study and received a Master’s degree in Electrical and Computer Engineering in 2012 under the supervision of Prof. Kyoung Mu Lee. I was a research intern at Google Cloud AI, hosted by Kihyuk Sohn.
