He specializes in the objective measurement and analysis of the built environment using GIScience methodology. His current research investigates the relationship between health-related behaviors and built environment at fine spatial and temporal scales. Using new-generation devices that measure activity and location in real time, the data are being used to find associations between the types of activities people engage in and the types of environments people use as they go about their daily lives. He collaborates with researchers specializing in nutritional epidemiology, exercise physiology, rehabilitation medicine, and psychology for the purpose of understanding the relationships between built environment, diet, and physical activity. Phil received a Master of Forest Resources degree in 1994 at the UW College of Forest Resources where he helped develop and implement a GIS for the Makah Indian Nation. His Bachelor’s degree (1983) is from Seattle University in Humanities. Prior to his current appointment, he worked as a GIS specialist for the College of Forest Resources, the City of SeaTac, the Seattle Water Department, and an instructor at the University of Washington and Green River Community College.
