Dr. Mehzabeen Mannan’s current research focuses on the management and analysis of large-scale river datasets, and the application of machine learning techniques to support river authorities in optimizing nutrient addition and improving river management strategies. Her work also encompasses the design of PFAS treatment systems, survey-based PFAS analysis across South Dakota, and studies on river ecosystem dynamics. Broadly, her research integrates life cycle assessment (LCA), circular economy principles, machine learning, and environmental systems analytics to advance sustainable approaches in water, waste, and air management.
