Lei You (Ph.D.)

Assistant Professor in Applied Mathematics

AI, Mathematics and Software

Department of Engineering Technology

Technical University of Denmark

I received my Ph.D. in Computer Science (specialized in Mathematical Optimization) from the Department of Information Technology at Uppsala University in 2019. During the PhD, I interned in The Boston Consulting Group (BCG) Gamma as a visiting data scientist. After the PhD, I had been working as a data scientist in Bolt and Wolt (Doordash) in the domain of on-demand logistics optimization.

My current research interests are causal inference & discovery and data-driven optimization. I am particularly interested in combinatorial optimization for causal structure learning and causal discovery. Additionally, I look into classic optimization problems in communications and networking, studying which from a perspective of causal research.
