Emma Frejinger

Emma Frejinger is Professor at the Department of Computer Science and Operations Research at Université de Montréal. She is the holder of the Canada Research Chair in Demand Forecasting and Optimization of Transport Systems, and the holder of the CN Chair in Optimization of Railway Operations. She has a Ph.D. in mathematics from École Polytechnique Fédérale de Lausanne, Switzerland. Her areas of expertise include both demand forecasting and optimization of transportation networks. Her research is mostly focused on developing new methodologies combining techniques from operations research and machine learning to tackle large-scale real-world problems. Her current major projects are related to the optimization of railway operations. Her students and herself have won several international awards, including the prestigious TSL Dissertation Prize bestowed by the INFORMS Transport Science and Logistics Society. She has realized numerous projects in collaboration with public and private actors. She is a member of CIRRELT, she works part-time as a scientific advisor for IVADO Labs and she is a founding fellow of AI Sweden.
