Barbara (Babs) Buttenfield

GIS; Cartographic Generalization; Multi-Scale Databases
Professor of Geography

303-492-3618 / Gugg 201d

I teach courses in Geographic Information Science, GIS Modeling, Cartography and Information Design. My research interests focus on generalization, understanding the impacts of scale and resolution on data and modeling, representing uncertainty, and designing visualization tools for environmental modeling. I am a Past President of the American Cartographic Association. In 2001, I was named GIS Educator of the Year by the University Consortium for Geographic Information Science. The Meridian Lab is directed by Professor Barbara P. Buttenfield and pursues research to develop and evaluate new software tools for Geographic Information Science.

Assistant Professor of Geography

303-492-4695 / Gugg 201f

I am an Assistant Professor at the Department of Geography, University of Colorado, Boulder, CO. Since 2009 I am also Research Fellow with the Fogarty International Center for Advanced Study in Health Sciences, U.S. National Institutes of Health (NIH), Bethesda, MD. I have a Ph.D. (2005) in Geography, University of Zurich, as well as an M.S. (2002) and B.S. (2001) in Forest Sciences, Dresden University of Technology, Germany. My research interests are centered around GIScience in general. In particular they are: Cartographic pattern recognition from historical maps, Spatial dynamic modeling approaches in health geography, Fuzzy Sets Theory in GIScience, Uncertainty in GIScience and spatial uncertainty modeling and Land cover change & retrospective landscape assessments.

Nicholas Nagle

Geographic Information Science, Spatial Analysis
Assistant Professor of Geography

865-974-6035 / 307 Burchfiel Geography Bldg.

Nicholas Nagle is a GIScientist/spatial analyst. He spends much of his time in the University of Tennessee Center for Business and Economic Research, where he coordinates efforts on demographic and economic research concerning the state of Tennessee. His primary research interests include scale issues in geographic data analysis, statistical mapping, and demography. He is currently working on a project to collect data and develop models explaining spatial patterns in social networks. He teaches Geography 515, (a graduate-level course in quantitative geography/spatial analysis), and courses in demography and urban geography.

Postodoctoral Researcher (University of Colorado at Boulder)

Matt Ruther (2012-2013)

Population estimation and demographic methods, spatial analysis and modeling

513-262-2948 / Gugg 301b

I am a Postdoctoral Researcher at the University of Colorado Boulder, having received my PhD in Demography from the University of Pennsylvania in 2012.  My research interests are in small area estimation and population change, demographic methods, immigration and domestic migration, and the social determinants of crime.  My dissertation, in which I studied the effect of immigrant populations on neighborhood and county homicide patterns, was funded in part through a Graduate Research Fellowship from the National Institute of Justice.  My work has been published in Demographic Research, Papers in Regional Science, and Journal of Sports Economics.
