Research in the Sivey Lab focuses on environmental organic chemistry and the chemistry of drinking water treatment. Specifically, our group examines the chemistry of aqueous disinfectants (including free chlorine and free bromine) as well as the generation disinfection by-products. The reactivity of biologically-important molecules (e.g., amino acids) toward chlorinating and brominating agents is of particular interest. Our group also examines the transformation mechanisms and environmental fate of agrochemicals (including pesticides and "inert" ingredients).
