I’m a fourth year PhD candidate at School of Computer Science and Engineering, University of Electronic Science and Technology of China, supervised by Prof. Kai Zheng. Moreover, I am co-supervised by Dr. Yan Zhao, an Associate Professor at Aalborg University. Previously, I received my M.E. and B.E. degree from University of Electronic Science and Technology of China and Taiyuan University of Technology in 2018 and 2021, respectively.

My research interests include spatio-temporal data mining, trajectory computing, finance technology, recommender system, vector database, and other data-driven applications.

Currently, I am looking for a job. If you are interested, please feel free to contact me via email denglw0830@gmail.com.
