Project Director and Principal Investigator

Dr. Ray Huhnke, professor of Biosystems and Agricultural Engineering at Oklahoma State University, is project director and principal investigator of the multi-institutional, five-year OK NSF EPSCoR Research Infrastructure Improvement Award No. OIA-1946093 (2020-2025), Socially Sustainable Solutions for Water, Carbon, and Infrastructure Resilience in Oklahoma. 

The $20 million project is a social science-led, multi-disciplinary collaboration among more than 30 social, physical, biological, engineering, and computational scientists from Oklahoma State University, University of Oklahoma, University of Tulsa, Southwestern Oklahoma State University, Langston University, East Central University, and Noble Research Institute. The research team is working to develop and test science-based solutions for complex problems at the intersection of land use, water availability, and infrastructure in Oklahoma.

The project also has a very strong outreach component. The grant is expected to provide education and workforce development programming to more than 150,000 Oklahomans of all ages during the five-year award. 

Dr. Huhnke has provided leadership for OK NSF EPSCoR awards since 2008. He served as project director for the five-year Adapting Socio-Ecological Systems to Increased Climate Variability RII award from 2013-2018 and was the lead researcher on the Building Oklahoma's Leadership Role in Cellulosic Bioenergy project from 2008-2013.

Dr. Huhnke is also director of the Biobased Products and Energy Center at OSU and associate director of the Sun Grant Program, South Central Region.
