Regina Clewlow is the CEO and Co-Founder of Populus, a mobility data platform for cities and private operators to deliver safe, equitable, and efficient streets through better data. Regina has over a decade of experience in transportation, building software to simulate the future of cities. Populus works with cities from coast to coast to access new mobility data from shared bikes, scooters, and cars for transportation policy and planning. Prior to her roles in industry, Regina received her Ph.D. in transportation and energy systems from MIT. As a research scientist at Stanford, UC Berkeley and UC Davis, she developed and led research on the travel behavior impacts of shared mobility services (e.g. Uber, microtransit) and autonomous vehicles. She is a Mass Transit 40 Under 40, National Engineers Week “New Face of Engineering”, EPA STARS Fellow, MIT Energy Fellow, and Department of Transportation Eisenhower Fellow.

Don MacKenzie leads the Sustainable Transportation Lab at the University of Washington, where he is an Assistant Professor of Civil & Environmental Engineering. With sponsorship from the automotive industry and federal, state, and local governments, the Lab develops and evaluates technical and policy solutions for making our transportation system more economically vibrant and environmentally benign, while providing access to opportunities for all. Current research includes charging behavior and infrastructure design for electric vehicles, the effects of vehicle automation on travel and energy demand, and the social impacts of emerging mobility services. Professor MacKenzie holds a PhD in Engineering Systems and SM in Technology and Policy, both from the Massachusetts Institute of Technology, and a BASc in Chemical & Biological Engineering from the University of British Columbia. He is a member of the Transportation Research Board’s Standing Committee on Transportation Energy, and chairs its Subcommittee on Energy and Demand Implications of Connected and Automated Vehicles.
