Shih-Lung Shaw is Alvin and Sally Beaman Professor and Arts and Sciences Excellence Professor of Geography at the University of Tennessee, Knoxville. He also serves as the interim associate provost for international education at the University of Tennessee, Knoxville. He received his B.S. degree from the National Taiwan University and his M.A. and Ph.D. degrees from the Ohio State University. His research interests cover geographic information science (GIScience), transportation geography, time geography, GIS for transportation (GIS-T), and space-time analytics of human dynamics. His recent research has focused on space-time analytics of human activities and interactions in a hybrid physical-virtual world based on various types of individual tracking data such as cell phone data, online social media data, vehicle tracking data, travel-activity survey data, and population migration data. His research has led to the development of a space-time GIS for representation, analysis, and visualization of individual activities and interactions in a hybrid physical-virtual space.
