My research interests lie within two general fields of application: urban and neighborhood dynamics and urban transportation. My work on neighborhood dynamics has sought to understand how and why neighborhoods change according to their multidimensional quality of life or socioeconomic complexion. This research has employed a variety of statistical and computational techniques to understand space-time-multidimesional patterns of change and to disentangle the drivers of change including: self-organizing maps, sequential pattern mining, and structural equation modeling. I continue to be driven by the pursuit of novel methodological techniques that can deepen our understanding of neighborhood dynamics.
On the transportation side, I have worked in the area of bicycle and pedestrian safety, performing spatial analyses of bicycle crash locations and compared neighborhood-level risk factors between bicyclists and pedestrians. I am also interested in spatial accessibility and spatial equity as it relates to public transport; specifically, my work in this area has examined accessibility patterns to urban opportunities via a newly implemented Bus Rapid Transit system in Cali, Colombia. I currently serve as the chair of the Transportation Geography Specialty group of the AAG.
Geographic Information tools and spatial analytical/statistical methods form the core of my research methodological approach. The courses I teach are along these lines including: Spatial Thinking, Fundamentals of Geographic Information Systems, Spatial Modeling for Social and Economic Applications, and Spatial Database Development.
