Hi, I am Yunlong Wang (王云龙), a sixth-year PhD candidate at Shanghai Jiao Tong University (SJTU), Antai College of Economics and Management (ACEM), advised by Dr. Ying Rong and Dr. Taotao He. I am currently in a two-year visiting program (23 fall - 25 fall) at the University of Colorado Boulder (CU Boulder, Leeds School of Business), advised by Dr. Rui Zhang.
I am on the 2025-2026 academic job market.
My research lies at the intersection of discrete choice modeling, optimization, and revenue management, using mixed-integer programming approaches. I focus on the computational and algorithmic aspects of discrete choice models, as well as (social) network-based influence problems. I also have training in continuous optimization, particularly in advanced methods for algorithmic acceleration.
I have a couple of industry internship experiences at Tencent (AI Lab) and Huawei, where I worked on accelerating machine learning algorithms and optimizing scheduling strategies for 5G base station operations, respectively.
