David O'Sullivan


I am currently an Associate Professor at the University of California, Berkley. I have a PhD from the University of London, Center for Advanced Spatial Analysis, a Masters of Science from the University of Glasgow in Cartography and Geo-information Technology and a BA/MA in Engineering from the University of Cambridge. 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.

Course Spotlight

pile of maps

Cartography and Visualization (GEOG 486) covers design principles and techniques for creating maps with contemporary mapping tools. Students will be introduced to future-focused application topics such as augmented and virtual reality, mapping with multivariate glyphs, the visual depiction of uncertainty, interactive geovisualization, and (geo)visual analytics, and decision-making with maps and mapping products. Visit the course.
