Hello! I am a Ph.D. student at the School of Computing, National University of Singapore. I am advised by Prof Wynne Hsu and Prof Mong Li Lee. My research interests lie in out-of-distribution generalization and AI for healthcare.

I received my Bachelor’s degree in Computer Science from the School of Computing, National University of Singapore in 2021. My thesis was advised by Prof Zhiyong Huang.
