My interests lie at the intersection of urban and regional planning, spatial analysis, and landscape ecology. Put simply, my work applies spatial analysis tools to study issues related to urbanization and the urban environment—issues such as: drivers of land use change; natural hazards mitigation in the urban-wildland interface; the relationship between crime and the natural environment; the public health and energy use impacts of urban form; the equitable spatial distribution and property value impacts of environmental amenities and liabilities; the effects of homeowner behavior and residential design on residential non-point source pollution; and the impacts of local and regional land use policies on urban sprawl. The tools I use to address these issues include Geographic Information Systems (GIS), remote sensing, dynamic modeling, and spatial statistics/econometrics. Some of my research focuses specifically on developing and advancing methodologies built on these tools. My methodological research has addressed issues such as: characterization of forest fragmentation in suburban and exurban areas; mapping approaches for quantifying the spatial distribution and flow of urban ecosystem services; assessing geographic variation in statistical relationships (i.e. “non-stationarity”); segmentation algorithms for deriving geographic boundaries of housing markets or neighborhoods; policy scenario evaluation procedures in urban growth models; spatial characterization models of watershed vulnerability to urbanization pressures; and techniques of fine-scale land cover mapping of vegetation in heterogeneous urban areas.
My most recent research interest focuses on how cities consume energy and how energy footprint relates to urban form, transportation systems, climate, and water transfers. This is the topic of my book, The Very Hungry City, published by Yale Press in January 2012. Follow the link for more details on the book including chapters, press, reviews, interviews, etc.
