UTIA Faculty Spotlight | Dr. Jim Brosnan


Originally from Massachusetts, Dr. Jim Brosnan earned a M.S. from the University of Massachusetts Amherst, along with both a B.S. and Ph.D. from The Pennsylvania State University. He came to UTIA from the University of Hawaii where he worked as an Assistant Specialist in Turfgrass Management. Currently, Dr. Brosnan is an Associate Professor of Turfgrass Weed Science in the Department of Plant Sciences.

Dr. Brosnanís research focuses on strategies for controlling unique and problematic weeds of turfgrass systems, particularly annual bluegrass (Poa annua) and goosegrass (Eleusine indica) with resistance to herbicides. He has published over 100 peer-reviewed research articles and has been recognized by the Crop Science Society of America, as well as both the Northeastern and Southern Weed Science Societies for his research efforts. Recently, Dr. Brosnan was invited to give a keynote presentation at the Global Herbicide Resistance Challenge on managing herbicide resistant weeds in turf.

Despite receiving limited funding from federal agencies, Dr. Brosnan has successfully been able to support his research efforts via competitive grant funding from the United States Golf Association as well as partnerships with several industry partners. These relationships have facilitated the development of new weed management technologies for Tennesseeís $5.8 billion turfgrass industry.

In 2017, Dr. Brosnan was named Director of the new UT Weed Diagnostics Center (WDC). Supported by both AgResearch and UT Extension, the WDC is a revenue-generating entity to provide end-users a wide range of diagnostic services from basic weed identification to herbicide resistance screening. All diagnostic test results are complemented with research-based control recommendations to promote proper weed management practices in the field.
