Andrew A. Li

I am the Frank A. and Helen E. Risch Assistant Professor of Operations Research at CMU Tepper. I completed my Ph.D. at the Operations Research Center at MIT.

My research interests are in statistics, optimization, and machine learning, with applications to operations management and medicine. I am currently funded by an NSF CAREER Award.

Finally, I've gotten to work with some fantastic Ph.D. students:

• Lin An
• Tianyi Peng (Assistant Professor, Columbia Business School)
• Kyra Gan (Assistant Professor, Cornell Tech)
• Su Jia (Research Assistant Professor, Cornell ORIE)
  Winner, Dantzig Dissertation Award
• Melda Korkut (Applied Scientist, Amazon Machine Learning Science)
