I am a final-year Ph.D. student in the Department of Industrial Engineering and Management Sciences, Northwestern University, where I am fortunate to be advised by Prof. Diego Klabjan. My major is applied statistics and statistical learning with a minor in simulation and stochastic analysis.

I am also fortunate to work with Prof. Imon Banerjee.

My research interests broadly encompass statistics, statistical machine learning and applied probability. Specifically, my work focuses on theory and computational methods for uncertainty quantification.

From June to September 2025, I interned with the Middle Mile Science Team at Amazon as an applied scientist. My hosts were Phil Kaminsky and Adam Elmachtoub. From June to December 2024, I worked with the Global Pricing Team at McDonald’s as a recommender system researcher. My host was Zhivko Gochev.

Before joining Northwestern, I received my B.S. degree in mathematics and applied mathematics from Fudan University, and my M.S. degree in mathematical statistics from Purdue University, where I was fortunate to be advised by Prof. Raghu Pasupathy.

My Erdős number is 3: Ziwei Su - Diego Klabjan - Craig A. Tovey - Paul Erdős.

I will be presenting at INFORMS 2025 in Atlanta.

• Tuesday, October 28 (4:15–5:30 PM).
• Invited session “Bandits and Stochastic Control” — Room A406 (Building A, Level 4).
• Talk: Statistical Inference of Controlled Markov Chains: CLT for Transition Probabilities and Applications to Offline RL
