Biography and Research Information
OverviewAI-generated summary
L. Tom Barber's research focuses on weed science, particularly herbicide resistance in agricultural settings. He has investigated mechanisms of resistance in Palmer amaranth and barnyardgrass to herbicides such as glufosinate and florpyrauxifen-benzyl. Barber has also examined the implications of herbicide spray drift on pollinator foraging sources and studied weed management costs and practices in Arkansas rice production. His work also extends to the application of wastewater sequencing for monitoring infectious diseases, including SARS-CoV-2 variants in elementary schools and the broader community.
Barber collaborates with several researchers at the University of Arkansas at Fayetteville, including Jason K. Norsworthy, Trenton L. Roberts, Amar S. Godar, and Edward E. Gbur. He has authored 64 publications, with an h-index of 17 and over 1,230 citations.
