Biography and Research Information
OverviewAI-generated summary
Brian E. Haggard, Director of Biological and Agricultural Engineering at the University of Arkansas at Fayetteville, studies nutrient dynamics in aquatic ecosystems. His research has focused on phosphorus mitigation to address river eutrophication, investigating factors that influence phosphorus runoff, particularly in pastures fertilized with poultry litter. Haggard has also examined nutrient retention within streams, accounting for point-source inputs and their impact on overall watershed phosphorus cycles.
His work includes the development of practical guidance for data collection on small watersheds related to discharge and water quality. Haggard has a significant publication record, with 214 total publications and 3,978 citations, evidenced by an h-index of 37. He has received federal funding, including a $387,283 NSF grant as Co-PI for a REU Site focused on the assessment and sustainable management of ecosystems at the nexus of food, energy, and water systems. Haggard collaborates with researchers at the University of Arkansas at Fayetteville, including Abbie L. Lasater, Bradley J. Austin, and Erin M. Grantz.
