My educational background and research interests both lie at the intersection of chemistry and biology. Specifically, I focus on the use of chemical tools to uncover insights about biological systems.

In the Peeler Lab, we utilize a chemical tool called genetic code expansion in order to study protein function. Genetic code expansion enables cells to express proteins that contain amino acids beyond the naturally-occurring amino acids that are typically available to cells. This ability to expand the genetic code and utilize non-canonical amino acids allows us to produce proteins that are intractable to traditional molecular biology approaches. And once these proteins are expressed, we can study their biological functions.

Undergraduates in the Peeler Lab gain experience in a number of chemical biology and biochemistry techniques, including molecular cloning, tissue culture, protein expression and purification, and enzyme assays.
