Ning Duan

I am a final-year PhD student in the School of Operations Research and Information Engineering (ORIE) at Cornell University, advised by Professor Samitha Samaranayake. Before Cornell, I received my B.S. in Mathematics from Boston College.

My research develops scalable optimization methods, including mixed-integer programming and network design, for public transit and other transportation systems. Broadly, my interests lie in decision-making in networked service systems.

Earlier in my PhD, I contributed to a decision-support model for COVID-19 reopening strategy, leveraging techniques from stochastic modeling, simulation and optimization.
