Research Interests

The activity of microbes greatly affects the biogeochemical flow of nutrients and contaminants in the environment. Our research primarily focuses on the thermodynamics and kinetics of aqueous and interfacial reactions involving biogenic exudates that contribute to understanding the biogeochemical cycling of natural and anthropogenic species. We blend traditional wet-chemical, field, and microbiological methods with modern spectroscopic, microscopic, molecular biology, and theoretical techniques to obtain an understanding of mechanisms and reaction pathways on molecular to macroscopic scales.
