Sam Stehle is a Postdoctoral Researcher working on the Building City Dashboards project. He received his PhD from the Pennsylvania State University in August 2017 in Geography, where his dissertation used topic modeling and geographic information retrieval to map geographic networks in digital media during the Catalonian independence movement of 2014. For his Masters work at Penn State, Sam built a pattern matching procedure based on sequence alignment which matched known spatio-temporal patterns in big event data. Sam has taught courses in GIS, urban geography, and energy land management and is a former fellow in Penn State's National Science Foundation-funded interdisciplinary IGERT program on Big Data and Social Science.

In NCG, Sam is working to collect, archive, analyse, and visualize real-time city data. City dashboards provide both a history and a current view of the urban social environment, so Sam is seeking effective communication of this temporality and how to provide new ways of interacting with temporal information to provide a useful window into city function and navigation for a variety of users.
