PRINCIPAL INVESTIGATOR


Andres Sevtsuk, PhD asevtsuk[at]mit.edu

Andres Sevtsuk is Head of the City Design and Development Group and an Associate Professor (with tenure) of Urban Science and Planning at the Department of Urban Studies and Planning, where he also leads the City Form Lab. His research focuses on the influence of urban form on sustainable travel behavior and on public qualities of built environments--urban ground floors, main streets, and amenity location patterns. His work contributes to making city environments more walkable, sustainable and equitable, bridging the fields of urban design, spatial analytics and mobility research. Andres is the author of the Urban Network Analysis framework and software tools, used by researchers and practitioners around the world to model pedestrian activity in cities and to study coordinated land use and transportation development in ways that reduce transportation carbon emissions. He has published a book entitled “Street Commerce: Creating Vibrant Urban Sidewalks” with Penn Press and before that, "Urban Network Analysis: Tools for Modeling Walking and Biking in Cities" with Tianjin University Press. Andres has collaborated with a number of city governments, international organizations, planning practices and developers on urban designs, plans and policies in both developed and rapidly developing urban environments, including those in US, Indonesia, Australia, Lebanon, Estonia and Singapore. He has led various international research projects, published in planning, transportation and urban design journals, and received numerous awards for his work.

Starting in spring 2025, Rounaq will be joining the Georgia Institute of Technology as an Assistant Professor of Planning.
 


 
 
Maryam Hosseini maryamh[at]mit.edu  

Rutgers University PhD, 2022.

Maryam recently completed here postdoc at the City Form Lab, focusing on pedestrian accessibility and walkability in urban public spaces. Prior to joining CFL, she was a research associate at the Visualization and Data Analytics Research Center (VIDA) at NYU. Her research aims to address existing gaps between planners’ needs and available urban analysis tools by developing new, theory-rich technologies for large scale assessment of the quality of the built environment at the intersection of urban planning, economics, and computer science. Her main research interests are pedestrian mobility infrastructure and planning, assessing the impact of the built environment on walkability and accessibility, and human-focused design of cities using computer vision, spatial analysis, and agent-based modeling. She develops generalizable models for automated auditing of pedestrian facilities, specifically sidewalks, and uses the developed models to create pedestrian level data sets at scale, specifically for less resourced cities. Her work highlights how these generalizable models can be applied to cities for which built environment datasets are lacking today. Starting in spring of 2025, Maryam will be joining the UC Berkeley as an Assistant Professor of Planning and Data Science.
