Assistant Professor of Operations
CONTACT INFO
Sebastien Martin is an Assistant Professor of Operations at Kellogg. He received his Ph.D. in operations research from MIT and an M.Sc. in applied mathematics at Ecole Polytechnique. Before joining Kellogg, he was a postdoctoral research fellow at the ridesharing company Lyft. He is a twice Edelman Award Laureate (2019 and 2023) and has received the George Dantzig and TLS Society dissertation awards.
His research is at the interface of optimization, transportation, and public policy. His work on public school operations combines complex large-scale logistics problems with policy decision-making. For example, he helped redesign the school-bus routes of Boston Public Schools in 2018, and he helped change the school schedules of the San Francisco Unified School District in 2022. He is also interested in online platform operations and the gig economy, using modeling and optimization approaches to help gig workers be as productive as possible. In 2022, he helped the ridesharing company Lyft change its online matching algorithm, using online reinforcement learning to better match drivers to passengers, resulting in more than 30 million dollars of additional annual revenue for the drivers.
