<Emily Zhang>

Hi! I am a rising fifth-year PhD student in the Operations Research Center at MIT, co-advised by Prof. Georgia Perakis and Prof. Retsef Levi.

My research develops new analytical methods to address critical problems in food systems, with the dual goals of reducing food waste and improving access to healthy food. In collaboration with the Massachusetts Department of Transitional Assistance, I am evaluating the impact of vendor additions on the utilization of a food subsidy program. In partnership with Met Council, I am working to improve the allocation of food to local pantries. More broadly, I design models and algorithms that shape practical solutions while advancing general methodologies in optimization, causal inference, inventory management, and data-driven operations.

I completed my undergraduate studies at MIT in 2021 with dual B.S. degrees in Computer Science and Mathematics. I am grateful to be supported by a National Science Foundation (NSF) Graduate Fellowship and the Ida M. Green Fellowship.

I’m on the 2025-2026 academic job market! ⭐
