I focus mostly on the ways and reasons behind the spatial organization and interactions of people in different spaces and in relation to their environment. Though I am concerned with physical systems, the physical systems I study are all either entirely man-made or nearly so. My focus is always on the implications for human use (or disuse) of the physical systems rather than the systems themselves.

Within urban geography, I am primarily interested in the sub-discipline of urban morphology, which is the study of the shape, form, and structure of urban spaces. This includes the principal physical structures of urban areas (streets, public squares, street blocks, land plots, and buildings) along with the agents and processes that drive their evolution over time. Even more specifically, I include work in the more traditional historico-geographical approach (primarily qualitative - quite akin to historical geography) and the spatial analysis/urban morphometrics approach (a primarily quantitative lens on the spatial patterns, structures, and relationships in a city).

With the form and function of cities as my primary analytical lens, I seek to uncover, define, interrogate, and/or "operationalize" physical form, embodied function, "invisible" drivers, and causal mechanisms. For instance, how do the material infrastructure, population and processes connect to the immaterial? How can we better understand one by understanding the other? I am especially interested in the spatial aggregation of phenomena (neighborhoods, formality/informality, spatial signatures, taxonomies), their boundaries (hinterlands, neighborhoods, "estuaries," confluence zones, liminal zones), and the way they are connected (transportation networks, physical and non-physical flows of urban "metabolism," spatial/political/social context).
