Biography
I am a Postdoc Research Fellow at DeepMed/ZhangLab, supervised by Prof. Zhang Yang. Previously, I completed my PhD at the NExT++ lab at NUS, where I was supervised by Prof. Chua Tat-Seng and co-supervised by Prof. Kawaguchi Kenji. I was also fortunate to be mentored by Prof. Wang Xiang at the University of Science and Technology of China (USTC). Before my PhD, I spent nine wonderful months at THUNLP, where I was supervised by Prof. Zhiyuan Liu. Yes, my first supervisor's name spells the same as mine! My research primarily focuses on AI for Science, particularly Multi-modal Generative Modeling for emerging scientific modalities such as proteins, RNAs, and small molecules. Additionally, I have a keen interest in Diffusion Models, Natural Language Processing, and Graph Neural Networks.
Prospective Collaborations
I am always looking for passionate and motivated graduate and undergraduate students to collaborate with me on AI for Science. Feel free to shoot me an Email if you’re interested in having a chat over coffee at the Coffee Bean & Tea Leaf at the School of Computing of NUS.News
