PERSONAL SPACE
Shujun (Erin) Xia
You can call me Erin.
I'm a senior at Columbia University and City University of Hong Kong studying Computer Science. Welcome to my little corner of the internet.
Research interests. My research interests include efficient, reliable, and responsible AI systems, with a focus on model interpretability, knowledge editing, and reinforcement learning.
I was extremely fortunate to begin my research journey with the great Prof. Antoni Chan, my first research supervisor.
