Haiqing Gao

I'm a third-year PhD student in the Industrial Engineering and Management Sciences department at Northwestern University.

I received my B.S. in Applied Math and M.Phil. in Computer Information and Engineering from the Chinese University of Hong Kong, Shenzhen. I'm currently co-advised by Seyed M.R. Iravani and Sean R. Sinclair, and my research focuses on data-driven sequential decision-making in non-profit operations. My recent work applied dynamic programming (DP) models to provide insights for optimizing food pantry operations of food banks.

Research

I'm interested in applying machine learning optimization and stochastic processes to the design and control of non-profit operations. My previous work has focused on data-driven machine learning in areas such as online matching platforms, healthcare prevention, and distributed learning. Currently, my research is centered on the design of operational systems for non-profit organizations.
