I am an assistant professor at The University of Hong Kong, where I direct the Medical AI Lab. My research lies at the intersection of artificial intelligence and healthcare. We are dedicated to designing advanced machine learning algorithms for biomedical data analysis, with a primary focus on medical images, to improve medical decision-making. Specifically, we focus on: 1) developing multi-modal learning algorithms to intergrate multi-scale biomedical data for disease prevention, diagnosis, prognosis, and treatment design; 2) building real-world learning systems to learn reliable, trustworthy, and fair representations from imperfect medical data; and 3) developing causality-based learning algorithms to improve its interpretability for healthcare problems.

Before joining HKU, I was a postdoctoral research fellow at Stanford University, working with Prof. Lei Xing. I obtained my Ph.D. degree in CSE, The Chinese University of Hong Kong in July 2019 and the B.Eng degree in CS, Zhejiang University in 2015.

I am looking for self-motivated PhD/Interns, who are interested in machine learning, computer vision, clinical NLP, and bioinformatics. Welcome to drop me an email with your CV and transcripts. Remote collaboration is also welcome!

If you are an HKU student interested in doing research with me, please send me an email.

Due to the large amount of emails I received, I may not be able to respond to each one individually.
