Bio

I am an Assistant Professor in the Geography Department of the University of Colorado at Boulder where I direct the spatial sciences node of the NSF-Census Research Network.   I’m a human geographer who works at the intersection of demography, GIS, and urban planning.

I know a lot about the American Community Survey (ACS) and much of my recent work has focused on developing ways to improve the estimation and use of the ACS.   I’ve developed methods for measuring neighborhoods using individual-level data from historical archives and have studied the relationship between neighborhoods and well-being.  I do some research on natural hazards, and in a recent issue of PNAS I developed a new way to measure social vulnerability to natural hazards.  In 2013 I served on the Department of Interior Hurricane Sandy Strategic Science Group.  My work has been profiled in Science and other outlets.  I won the Breheny Prize for the best paper in Environment and Planning, I won a kaggle.com data science competition on data visualization.  Prior to joining the faculty at Colorado I was the Associate Director of the S4 Initiative at Brown University.  Before Brown I was at the Columbia University Graduate School of Architecture, Planning and Preservation, first as a masters student and later as an Adj. Assistant Professor and Associate Research Scientist. Once upon a time I was the owner of an antiquarian bookshop in the Flatiron Building in New York City. I’m also a fisherman, a bird-watcher, a really good snowboarder, and a bike geek.  I program in R and Python and whenever possible I work to make my research reproducible by publishing data and code.

Note: For the 2015-16 academic year I am on leave from the University of Colorado working at Apple Maps.
