I am an Assistant Professor of Urban and Regional Planning at University at Buffalo. I've earned a Ph.D. from Interdisciplinary Ph.D. Program in Urban Design and Planning in University of Washington in 2013.

My general interests include the built environment, health, GIScience, and spatial data analysis.

My current research is primarily focused on the relationship between the built environment, walking, and health outcomes. Recently, I published a method paper on objective measurement of walking using accelerometers, GPS units, and travel diary.

Before joining UB, I was a research associate at Urban Form Lab in University of Washington, and a urban designer/researcher at Seoul Development Institute (currently the Seoul Institute) and Department of Architecture, Seoul National University.
