Guancheng "Ivan" Qiu

Ph.D. Candidate in Operations Research

Portrait of Guancheng Qiu

I am a fifth-year Ph.D. student in Operations Research at Georgia Institute of Technology, and the NSF AI Institute for Advances in Optimization (AI4OPT), advised by Prof. Pascal Van Hentenryck. My research focuses on applying machine learning to solve optimization problems, the verification of such machine learning models, and their applications in energy systems. Previously, I received my B.S. in Computer Science and B.S. in Applied and Computational Mathematics from the University of Southern California in 2020.
