Yiqun Lin

Research Fellow at UCL

Email: Email

I am currently a Research Fellow at University College London (UCL), working with Prof. Yukun Zhou and Prof. Pearse Keane. My research interests primarily center on medical image analysis and computer vision, with a specific focus on developing foundation models for healthcare applications.

Prior to joining UCL, I obtained my Ph.D. in Electronic and Computer Engineering from HKUST, advised by Prof. Xiaomeng Li. I completed my M.Phil. at CUHKSZ under the supervision of Prof. Shuguang Cui and Prof. Xiaoguang Han, and received my B.Eng. degree in Software Engineering from Tongji University.
