Maryam Hosseini maryamh[at]  

Rutgers University PhD, 2022.

Maryam is a Postdoctoral Associate in the City Form Lab, at the MIT department of Urban Studies and Planning (DUSP), 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.
