Dr. Jim Muir has been a grassland ecologist and plant scientist at Texas A&M AgriLife Research since 1997. Prior to that he worked in Mozambique (Africa) as a researcher, educator and community developer and continues to cooperate with researchers in South America, Africa and Europe. His primary focus is on cultivated pasture agronomy although he expands this to other areas including grassland restoration, rangeland management, cellulosic biofuels, small ruminant health, and environmental sciences.
