I'm an assistant professor in urban planning in the Department of City and Regional Planning at the College of Architecture, Art, and Planning at Cornell University. 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 have a new paper that uses mobile phone data to measure variation of ego-centric social contexts and how that changes our measurements of diversity and segregation.

Another paper I published recently compares neighborhood outcomes using the FHA redlining map in Chicago to the HOLC's.

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.
