About me

I am Xie Yuan, a Postdoctoral Research Fellow at the School of Computing, National University of Singapore. I completed my Ph.D. in Computer Science at Hunan University (HNU) in 2024 under the supervision of Prof. Keqin Li and Prof. Kenli Li. During my doctoral studies, I spent two years as a visiting Ph.D. student at NUS, advised by Prof. Roger Zimmermann.

My research focuses on trajectory classification, spatial crowdsourcing, and time series anomaly detection. You can find my CV here: Yuan’s CV

Please do not hesitate to contact me if you have any questions regarding my work or if you are interested in discussing research topics!
