Research Interests: 

Dr. Jia Yang, assistant professor in the Department of Natural Resource Ecology and Management at Oklahoma State University, is a member of the OK NSF EPSCoR Track-1 RII Award titled Socially Sustainable Solutions for Water, Carbon, and Infrastructure Resilience in Oklahoma. The $20 million EPSCoR research project is a social science-led, multi-disciplinary collaboration among social, physical, biological, engineering, and computational scientists. More than thirty researchers from across the state are working together on the project, which began July 1, 2020.

Dr. Yang's research interests include ecological modeling; fire ecology; impacts of climate change and disturbances on land ecosystems; natural resource conservation; GIS and remote sensing applications in natural resources.

Dr. Yang's work in the area of fire and ecosystem modeling directly supports the OK NSF EPSCoR project via Focus Area 2: Terrestrial Water & Carbon Dynamics (TWCD). The TWCD focus area is central to the wicked problems facing Oklahoma because of conflicting policy narratives that shape concerns about carbon management and risks associated with landscape management practices (e.g., wildfire risks). At the same time, linkages across the TWCD and other focus areas provide opportunities to engage key stakeholder groups in discussions addressing both problem definition and potentially sustainable solution sets. Land use/carbon cycle issues play this crucial role because of the interactions among terrestrial ecosystems and carbon and water cycling, which are in turn integral components of the other impact domains addressed in this research project.
