About
I am a PhD student at the Department of Data Science and Artificial Intelligence, The Hong Kong Polytechnic University (PolyU), advised by Prof. Jibin Wu and Prof. Kay Chen Tan. I also work closely with Prof. Yujie Wu and Prof. Guozhang Chen.
Prior to this, I obtained my M.Eng. degree in Biomedical Engineering from the Southern University of Science and Technology (SUSTech) in 2023, advised by Prof. Quanying Liu. Before that, I received my B.Eng. degree in Computer Science and Engineering from SUSTech in 2020, working with Prof. Jialin Liu and Prof. Xin Yao.
My current research mainly focuses on AI for Neuroscience.
