Lindsay Graff | Worcester Polytechnic Institute

Lindsay Graff is an Assistant Professor of Civil, Environmental, and Architectural Engineering at Worcester Polytechnic Institute. Her research focuses on designing safe and efficient mobility systems spanning multiple transportation modes. She is particularly interested in developing methods to address complex network design problems, with the goal of informing public policy decisions. Dr. Graff received her Ph.D. degree in Civil and Environmental Engineering from Carnegie Mellon University in 2025, her MS degree in Public Policy from Carnegie Mellon University in 2020, and her BSE degree in Mechanical and Aerospace Engineering from Princeton University in 2015. From 2015-2018, she worked for Delta Air Lines as an analyst in the Revenue Management department, where she contributed to the maintenance and development of the airline's travel demand forecasting model.
