I am the Bob and Mary Reusche Chair in Geographic Information Science, Director of the Center for Urban and Regional Analysis (CURA) and Professor in the Department of Geography at The Ohio State University in Columbus, Ohio, USA.   I am also a Courtesy Professor in the City and Regional Planning program in the Knowlton School,  a member of the Faculty Advisory Board of the Sustainability Institute and an Affiliated Faculty of the Translational Data Analytics Institute at Ohio State.  I also chair the Mapping Science Committee and I am a member of the Board on Earth Sciences and Resources of the US National Academies of Science, Engineering and Medicine.

My research and teaching focus on the intersection between geographic information science and transportation science. I want to understand how people use mobility and communications technologies to allocate scarce time among activities in geographic space – a perspective known as time geography.  I am also interested in the social dimensions of transportation, the relationships between mobility and public health and data-driven urban science to support livable and sustainable communities.  My main approach to questions of mobility, livability and sustainability is the development and application of GIS and spatial analysis techniques to extract information from fine-grained mobility and spatio-temporal data.

I am an urban enthusiast – I love to discover and explore cities.  I am one of those cycling nuts who believes that the bicycle is the greatest machine ever invented.  I also like outdoor recreation (such as hiking and backpacking), international travel and non-fiction books (especially history, science and technology).  I struggle to fit quality film and television into my life.

I live in a walkable and bike-friendly central city neighborhood of surprisingly hip Columbus, Ohio with my wonderful wife Susanne and our accurately named cat Shpilkies.
