I am a geospatial data scientist focusing on sustainable transportation. My research goals are to promote sustainable and resilient mobility from a social equity perspective. Empirically, my interests are transport geography, primarily in public transport and mobility equity. The core of my research questions is to mitigate and overcome car dependency in cities and to promote sustainability, accessibility, and social equity. Methodologically, I use GIScience, urban computing technologies, and space-time analytics from a data-driven perspective.

I am leading the EcoTran Lab at Auburn with a focus on transdisciplinary research of transportation geography & planning, transit system engineering, and emerging computing technologies. I am actively recruiting PhD, Master’s, and Postdoctoral Researchers. Please feel free to contact me via email with your CV and a 1-page cover letter if you are interested!
