DIRECTOR OF UNDERGRADUATE PROGRAMS
My research interests are in the areas of geographic knowledge representation, knowledge discovery, spatio-temporal data models, spatial cognition, AI approaches to knowledge representation, geocomputation, and GIS design.
Since the early 1990's, my work has centered on the representation of time and temporal dynamics, including database, visual and cognitive representation and how these interrelate. Arguing that the human user and the computer must be viewed as components of a single system, my book, Representations of Space and Time, explores an integrated perspective, including philosophical, cognitive and technical aspects. See www.geovista.psu.edu/stempo/ and www.geovista.psu.edu/STNexus for some of this work.
In a similar vein, I investigate approaches for developing advanced tools for deriving insight from large and diverse collections of space-time information.
I am also interested in the impacts of environment, and most particularly environmental pollution, on disease. This relates to my work on the representation and analysis of complex space-time processes.
