Kyomin Hwang

I am a Ph.D. student at Seoul National University, researching deep learning under the supervision of Professor Nojun Kwak. Previously, I earned my bachelor's degree in Computer Science from Kookmin University.

I am interested in advancing Trustworthy AI, with a particular focus on privacy, robustness, and interpretability. I also actively explore interdisciplinary applications bridging AI with other sciences (e.g., AI + Psychology).
