I am a Computational Designer at Google, currently working on Delve. Previously, I was the Senior Data & Design Researcher at the Brown Institute for Media Innovation at Columbia University.

I work at the intersection of data, visualization, urbanism, and the humanities, and I teach graduate level workshops and seminars on mapping, advanced GIS and data visualization. I’ve also worked as a research scholar at the Center for Spatial Research and the Spatial Information Design Lab, as an architectural designer for Carlos Zapata Studio and D.G.T. Architects, and as the GIS project coordinator for the Catholic Charities of New York.
