Hi, I am Tingsong Xiao (肖廷松 in Chinese). I am currently a Ph.D. student in Computer Science at the University of Florida, under the supervision of Dr. Zhe Jiang. My research interests include deep learning (especially Graph Neural Networks), explainable/interpretable AI, and event prediction. Check my CV for more details.

Previously, I got my bachelor’s degree in Data Science and Big Data Technology at the University of Electronic Science and Technology of China (UESTC) in 2021. During my undergraduate, I studied recommendation algorithms with Dr. Jie Shao. Later, I was admitted to UESTC for Master’s degree without an entrance examination due to excellence. I worked on Graph Neural Networks and Interpretable AI under the supervision of Dr. Xiaofeng Zhu and Dr. Xiaoshuang Shi.

I won the MICCAI 2022 Student Travel Award (Top 2%) in 2022 and the China National Scholarship (Top 1%) in 2020.
