Our work lies at the intersection of transportation, environment, health and well-being. We are currently collaborating with researchers across disciplines, such as urban planning, geography, civil and environmental engineering, communication, psychology, and public health.

Our team is committed to diversity and inclusion.


Huyen Le, Assistant Professor, Department of Geography; Core faculty, Sustainability Institute

Huyen’s work focuses on three major themes: (1) managing and modeling urban transportation; (2) physical and mental health outcomes resulting from exposure during daily travel and activities and (3) impacts of information and communications technology on transportation, energy efficiency, and other environmental outcomes.

Huyen was trained in transportation planning at Virginia Tech (PhD, 2019) and The University of Iowa (MS), and in urban construction management at Hanoi Architectural University (B.Eng.). Between college and grad school, Huyen worked as a planning consultant and applied researcher in Vietnam.

Huyen is a member of UCGIS’s TRELIS and Golden Compass, the two initiatives aiming at training and promoting women scholars in geospatial sciences. She’s also affiliated with the Translational Data Analytics Institute, STEAM Factory, and EmPOWERment Program at OSU.
