• Addressed data bias and quality issues in estimating the spatial extent of vernacular places based on over 10 years of Flickr social media metadata. Improved estimation accuracy compared to traditional approaches..
• Accurately delineated crisp boundaries of vernacular places using a two-class SVM classifier with 10-fold cross-validation using LIBSVM
• Devised methods for determining the disjoint extents of vernacular places from Flickr geotagged photos using a spatial scan statistic approach with an average estimation accuracy of 85%
• Created an effective linear programming model to identify significant polygonal clusters with anomalously high event rates in point datasets. Solved using Gurobi optimizer
• Processed and analyzed large volumes of taxi trip trajectories to identify spatiotemporal patterns of driver deviations from the shortest routes. Presented papers on this work at GIScience 2012 and other conferences

US

• Analyzed biking behavior differences between bicycle and electric-bike riders using two years of GPS trajectories collected on the UTK campus. The findings provided useful insights for planners to develop bike and.

US

• Explored the viability of using an off-the-shelf GPS app for the iPhone as a household-based travel survey method for collecting travel data. Presented the findings in a paper at the 2012 Household Travel Survey.
