Jason Warren currently serves on the faculty of Oklahoma State University as an assistant professor, and soil and water conservation/management extension specialist. Jason grew up on a small grain and cattle farm in Woods Co. OK. He earned a B.S. degree in Environmental Sciences in 1999 and M.S. in Plant and Soil Sciences in 2001 at Oklahoma State University. Jason continued his education at Virginia Tech, where he obtained a Ph.D. in Crop and Soil Environmental Sciences in 2005 and then spent two years as a Post Doctoral Research Soil Scientist at the USDA-ARS Animal Waste Management Research Unit in Bowling Green, KY. Dr. Warren’s research and extension efforts will focus on management practices to reduce soil erosion and improve soil quality in both the agricultural and urban landscapes. He will also be engaged in activities aimed at increasing water use efficiency and reducing the transport of contaminates to surface and subsurface waters. |
