Dwight David Eisenhower Transportation Graduate Fellow

Greg Griffin studies how planners and publics work together with technology, particularly through engaged scholarship in sustainable transportation and geographies of health. Currently, ​he is a Ph.D. candidate and member of the University of Texas at Austin School of Architecture's Urban Information Lab working on his dissertation, called "Sociotechnical Co-production of Planning Information: Opportunities and Limits of Crowdsourcing for the Geography and Planning of Bicycle Transportation". He also works as a researcher with the Texas A&M Transportation Institute, leading projects such as Street Noise Relationship to Vulnerable Road User Safety.

Previously, Greg worked as a state park planner and regional transportation planner, and taught Transportation Systems at Texas State University. Greg is a member of the American Institute of Certified Planners, bicycles whenever possible, and sometimes tweets @gregpgriffin.
