I am a geographer specializing in geographic information science, with research interests in the computational representation and analysis of geographic information. My research has spanned a number of topical areas, including spatio-temporal data modeling and analysis, environmental justice, and dasymetric mapping. Recently, I have become involved in several projects funded by the National Institute of Justice (NIJ) and the National Institutes of Health (NIH) revolving around modeling contextual geographic and social network effects on human behavior, particularly relating to substance use and crime. Of interest are the ways in which social and peer influences on behavior are embedded within place, and how such contextual influences may interact with characteristics of the individual to produce particular behavioral outcomes, such as criminal recidivism and drug addiction.
I believe that this line of research into the interaction between individual, social, and environmental factors in producing behavioral outcomes represents a key contribution that geographic information scientists can make to some of the world’s most pressing societal problems related to health and well-being. Notably, this type of research demands new and innovative geographic methodologies integrating quantitative and qualitative spatial data derived from sensors, surveys, and interviews with more traditional spatial data sources, such as the U.S. Census and satellite imagery. Interdisciplinary approaches are also a key component of such research, and I have benefited substantially from collaboration with colleagues in psychology, psychiatry, criminal justice, computer science, and statistics on these projects.
I currently serve as Secretary and on the Board of Directors for GISCI (GIS Certification Institute) and on the editorial boards of the following peer-reviewed journals: Annals of the Association of American Geographers, Geography Compass, Urban and Regional Information Systems Association (URISA) Journal, and Journal of Spatial Information Science. I formerly served on the Board of Directors for the University Consortium for Geographic Information Science (UCGIS), as Chair of the Association of American Geographers (AAG) Geographic Information Systems and Science Specialty Group (GISS-SG), and as Academic Councilor of the AAG Cartography Specialty Group (CSG).
