About Me

I’m a Ph.D. student in the Machine Learning and Artificial Intelligence (MLAI) lab at KAIST, under the supervision of Prof. Sung Ju Hwang. Prior to this, I obtained my Master’s degree also in the MLAI lab at KAIST. I obtained my Bachelor’s degrees (Aerospace Engineering, Biological Sciences) at KAIST.
My research interests include AI for science, deep drug discovery, and generative models.
