My educational background and research interests both lie at the intersection of chemistry and biology. Specifically, I focus on exploring biological systems using chemical tools.

In the Peeler Lab, we are studying biological oxidation-reduction (or redox) reactions. We are interested in understanding redox reactions that support cellular function as well as understanding how cells respond to oxidative stress. We specifically focus on redox-active enzymes that possess modified or atypical amino acids. Such enzymes are challenging to produce using traditional molecular biology, but we are able to express these proteins through genetic code expansion. Genetic code expansion allows for the incorporation of non-canonical amino acids into proteins in living cells. This approach allows us to generate homogenous samples of modified or otherwise atypical proteins which can be functionally compared to their unmodified, typical forms. These functional studies inform our understanding of redox biology.

Undergraduate researchers in the Peeler Lab gain experience in several chemical biology and biochemistry techniques, including molecular cloning, tissue culture, protein expression and purification, and enzyme assays.
