My research and teaching interests are eclectic, perhaps because I came to geography late with a first degree in engineering science. I am an urban geographer, with a particular interest in novel (and mixed!) geographic methods. Some common threads are fundamental concepts in spatial analysis, modeling and visualization, and the implications of geospatial technologies, computation, and especially, the complexity sciences, for how we can and should represent the world. How can we use the geographical representations we make to do geography, particularly (but not exclusively) urban and human geography? At the most general level I explore relationships between spatial structures and processes using the simulation models of complexity science. At heart this is the central idea of my recent book Spatial Simulation: Exploring Pattern and Process.
Dynamic spatial models focus attention on the neighborhood as a fundamental spatial concept. More concretely, this interest owes a great deal to growing up in the 1970s and 80s in Belfast (Ireland), a place where local urban geographies mattered a great deal. I have worked on measuring and modeling neighborhood characteristics in urban settings, particularly patterns of ethnic settlement. This research highlights the importance of scale to understanding segregation: for example, in US cities quite different scales are evident in the segregation from other communities of African-American compared to Asian and Hispanic groups. I am fascinated by urban change, particularly the spatial dynamics of rent, and how capital flows in contest with local communities, produce and remake urban landscapes over time.
Sitting at the boundary between quantitative and qualitative methods, I am intrigued by how narratives can be constructed using simulation models and have argued for narrative approaches to the analysis of models. This is shaky ground from a philosophy of science perspective. Statistical methods are how we traditionally cope with the biases of narrative explanations, but a lesson from complexity science is that a pervasive feature of geographical systems is how they scale up from local events to wider effects, strengthening the persuasiveness of narrative explanations. Finding ways to balance narrative explanation with statistical methods is an area for further research.
Looking ahead, a key challenge is to understand how near-ubiquitous geospatial technologies (cellphones, the Internet, web-mapping, GPS) actively shape the sociospatial (urban) world. Spatial search, geo-tagging, and location-based services alter how places are perceived, locking-in misconceptions, and creating new perceptions. Notions such as ‘hotspots’—whether of crime, ill-health, or poverty, but rarely, if ever, of wealth—increasingly, ironically, have broad effects on policy, as ‘targeting’ turns communities into ‘segments’, neighborhoods into ‘lifestyles’, and people into ‘profiles’. Studying these phenomena requires theoretical insight and technical expertise, and I am enthusiastic about developing both, in collaboration with colleagues and students, at all levels.
