Zhaoqi Zhang

I obtained my Ph.D degree from the College of Computing and Data Science (CCDS), Nanyang Technological University (NTU), Singapore, under the supervision of Prof. Gao Cong and Prof. Siqiang Luo. Prior to joining NTU, I received my Bachelor’s degree in Software Engineering from Dalian University of Technology.

My research interests lie broadly in Spatiotemporal Data Mining, Representation Learning, and Causal Inference. My research aims to develop data-driven and causal learning methods for understanding and modeling complex urban systems. Beyond academic research, I have also worked on advertising allocation optimization problems in industry collaborations.

I am currently seeking postdoctoral opportunities in related research areas.
