Research Projects

Research in our group 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 of disinfection by-products.

Speciation of free bromine, from Sivey, et al., 2013, Environ. Sci. Technol. 47, 8990.

The reactivity of biologically-important molecules (e.g. amino acids) towards chlorinating and brominating agents is of particular interest.

Reaction pathways of lysinyl side chains upon exposure to free chlorine or free bromine, from Sivey et al., 2013, Biochemistry 52, 1260-1271.

We also develop novel methods for selectively quantifying active halogenating agents in aqueous systems.

Our group also examines the transformation mechanisms and environmental fate of agrochemicals (including pesticides and “inert” ingredients).

Abiotic transformations of the safener dichlormid into monochlorinated products, from Sivey and Roberts, 2012, Environ. Sci. Technol. 46, 2187 – 2195.
