Anson Stewart is a Research Scientist in DUSP and Lead for Analysis and Research at a small software firm. He researches how public transportation can shape more sustainable and accessible cities, drawing on collaborations with planning professionals and community groups, international perspectives, and experience developing cloud-based software to analyze large transportation datasets. In his dissertation, Anson leveraged such software to support interactive stakeholder workshops and calculate measures of urban accessibility that incorporate detailed land-use and vehicle location data. Anson has worked for public transportation agencies in Los Angeles, London, and Santiago de Chile and has participated in urban design workshops in Colombia and China, among other places. In addition to advising student research, Anson has taught transportation planning graduate classes at MIT. Prior to completing his PhD, Anson earned master’s degrees in transportation and city planning at MIT, and a BA (urban studies) and a BS (engineering) at Swarthmore College. As a 2010-2011 Thomas J. Watson Fellow, he spent a year in Latin America and Africa studying emerging bus rapid transit systems and their impacts on the environment.
