Biography and Research Information

OverviewAI-generated summary

Brian E. Haggard's research focuses on environmental monitoring and water quality, particularly concerning nutrient dynamics and the occurrence of harmful algal blooms in freshwater systems. His work investigates the influence of agricultural practices, such as the use of poultry litter and swine slurry, on phosphorus and nitrogen forms in runoff, and their subsequent transformations in aquatic environments. Haggard also studies the factors affecting cyanobacterial bloom formation and microcystin production, including nutrient concentrations and physicochemical properties of water bodies. His recent publications explore the predictive capabilities of machine learning models for monitoring harmful algal blooms and chlorophyll-a levels, and the relationship between raw fluorescence measurements and cyanobacterial toxins. He has also examined the impact of natural characteristics and human activities on turbidity and ion concentrations in streams.
