Hello! I'm Wenfei Xu, a PhD candidate in urban planning at Columbia GSAPP. My main research traces the legacies of historical structural disinvestment and asks how they have shaped present-day inequality and processes of neighborhood change.
I made a map tool that looks at the socioeconomic and demographic trajectories over from 1930 to 2016 of areas graded by the HOLC.
My other research interests include: using spatial big data to improve our understanding of social context, urban data science, and mapping and visualization as exploratory techniques.
I currently work at the Department of Homeless Services as a data scientist and teach in the Design for Social Innovation program at the School of Visual Arts.
