About Me

I am a PhD student in the Department of Computer Science at Western University (University of Western Ontario), Canada, co-advised by Prof. Charles Ling (Fellow, Canadian Academy of Engineering) and Prof. Boyu Wang. My research focuses on domain adaptation and AI for chemistry, particularly in developing novel methods for graph neural networks and their applications.

Previously, I completed my Bachelor's degree in Software Engineering (Elite Program) at the University of Electronic Science and Technology of China (UESTC), where I worked with Prof. Zhao Kang on graph representation learning and contrastive learning.
