About
I am Junfeng Xia (夏俊锋), a 2nd-year master's student in Biomedical Engineering at Southern University of Science and Technology, advised by Prof. Quanying Liu (刘泉影). I expect to graduate in June 2027 and am applying for Fall 2027 Ph.D. programs. Before joining SUSTech, I received my B.Eng. in Computer Science and Technology from Zhengzhou University, where I was advised by Prof. Qidong Liu (刘起东).
I am especially interested in three questions:
- How can robust neural representations be learned from heterogeneous brain signals?
- How should multimodal neural representations be fused?
- How can multimodal neural representations become useful brain knowledge?
