Jiangze (Jay) Han

I am a Postdoctoral Research Scientist in the IEOR & DRO at Columbia University, where I work with Dr. Vineet Goyal and Dr. Will Ma.

I will join the CUHK Business School as an Assistant Professor in the Department of Decisions, Operations and Technology in August 2026.

I obtained my Ph.D. in Management Science in the Operations and Logistics division, Sauder School of Business, University of British Columbia. I was fortunate to be advised by Dr. Christopher Thomas Ryan, Dr. Tim Huh and Dr. Mahesh Nagarajan. 

Prior to my Ph.D., I received my bachelor degree from Shanghai University of Finance and Economics, advised by Dr. Bo Jiang.

I visited the Department of Mathematics at the National University of Singapore in 2023.

Besides my above advisors, I also work with: Jiding Zhang, Mengzhenyu Zhang, Oussama Hanguir, Xihua Zhu, and Fuxi AI lab.
