Ludmilla Aristilde joined the faculty in the Department of Biological and Environmental Engineering in the Fall of 2012. 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. After emigrating to the States, she came to Cornell and completed a dual-degree program with a B.S. in Science of Earth Systems and a B.F.A. in Fine Arts. She went on to the University of California-Berkeley where she obtained her M.S. in Environmental Engineering and Ph.D. in Molecular Toxicology. Her research was on the environmental chemistry and toxicology of pharmaceutical compounds discharged in waters and soils. After Berkeley, she went to Grenoble (France) as an American Fulbright Scholar to advance her study of spectroscopic techniques to investigate the trapping of organic contaminants by mineral particles. Prior to her return to Cornell, she spent three years as a NSF Postdoctoral Fellow at Princeton University where she studied molecular biology tools to address problems at the interface of environmental chemistry and biological processes.

Research Focus

The goal of the Aristilde Group is to contribute to a fundamental understanding of the “why” and “how” of the environmental behavior of biologically active organic molecules, with implications for ecosystem health, agricultural productivity, and biotechnology. We conduct molecular-scale investigations that combine experimental and computational approaches to elucidate the mechanisms that control the biological and physical fate of organic compounds. Our current research activities investigate bacterial metabolism of natural organic substrates, interactions of organic matter and contaminants with natural particles, bacterial responses to organic contaminants, and dynamics of nutrient-cycling extracellular enzymes.

Teaching Focus

Professor Aristilde teaches students environmental chemistry and its applications in the environmental engineering processes. At the undergraduate level, she focuses on introduction to environmental engineering, soil chemical processes, and principles of water chemistry. At the graduate level, she works with students on physico-chemical thermodynamics, physical chemistry of natural particles, and chemical toxicology of organic contaminants. Her current courses are BEE 2510 Engineering Processes for Environmental Sustainability and BEE 4200/6200 Surface Chemistry of Particles in Natural and Engineered Processes.
