Research in the Sivey Lab focuses on environmental organic chemistry and the chemistry of drinking water treatment. Specifically, the group examines halogenation kinetics involving aqueous disinfectants (including free chlorine and free bromine) as well as the generation of disinfection byproducts. The reactivity of biologically-important molecules (e.g., amino acids, pesticides, and “inert” agrochemical ingredients) toward chlorinating and brominating agents is also of interest.
