Washington, D.C.

I am a Social Science Analyst for the United States Department of Housing and Urban Development (HUD). I have nearly a decade of experience working with spatial data and Geographic Information Systems (GIS). My work focuses on housing issues, typically spatial analysis questions regarding vacant housing and low-income rental assisted housing populations.

I am an adjunct lecturer for the University of Maryland, Baltimore County's master's in GIS program and a Fellow at the D.C. Policy Center.
