Ludmilla Aristilde is an Assistant Professor in the Department of Biological and Environmental Engineering. While growing up in Haiti, her interest in environmental issues was sparked by witnessing the impacts of deforestation on the environment and the links between water pollution and health during an epidemic outbreak of cholera. Her research focus is to address problems at the interface of environmental chemistry and environmental health through mechanistic investigations of the environmental fate and effects of emerging organic contaminants, natural toxins, and other biologically active organic molecules.
The goal of the Aristilde Group is to contribute to a mechanistic understanding of the “why” and “how” of the environmental behavior of biologically active organic molecules, with implications for environmental contamination, ecosystem health, soil fertility, and agricultural productivity. Of particular interest is the fate and effects of emerging contaminants, including pharmaceuticals, antibiotics, hormones, and natural toxins in soils and surface waters. Additionally, she studies the reactivity and fate of important organic substrates and macromolecules in soils.
Professor Aristilde teaches students environmental chemistry and its applications in the natural environment. At the undergraduate level, she focuses on introduction to environmental engineering and environmental toxicology, soil chemical processes, and principles of water chemistry. At the graduate level, she works with students on environmental-chemical thermodynamics, physical chemistry of soil-contaminant interactions, and chemical toxicology of organic contaminants. Her current course is BEE 2510 Engineering for a Sustainable Society.
