About Me
Hi! I am Li (Shawn) Li, a PhD student at Thomas Lord Department of Computer Science, University of Southern California, supervised by Prof. Yue Zhao.
Before my PhD study in the USA, I spent wonderful years in Singapore and cooperated with great professors. I served as a research associate at Nanyang Technological University, working with Prof. Aixin Sun. I earned my Master’s degree from National University of Singapore in 2024, where I contributed as a research intern under the guidance of Prof. Tat-Seng Chua and Prof. Roger Zimmermann. Prior to that, I successfully completed my Bachelor’s degree at TongJi University, China in 2022. My research interests are centered around multimodal learning, Out-of-Distribution detection, and information retrieval.
