Assistant Professor of Chemistry
  • Profile

    Research in my laboratory lies at the interface between organic chemistry and chemical biology. We are interested in designing chemical tools for the development of peptide-based medicines. Normally derived from the 20 natural amino acids, peptides are versatile compounds with a growing list of therapeutic applications, including cancer, diabetes, and infections. While peptides are a promising alternative to traditional small molecule medicines, chemical modifications to their natural sequences are often required in order to enhance their therapeutic activity. Performing organic reactions on biomolecules like peptides, however, is challenging. First, peptides are structurally complex, and contain many reactive functional groups. Second, peptides require aqueous solvent to dissolve and function properly. Alternatively, many synthetic methods are incompatible with water and require organic solvents.

    My research group is interested in bridging the gap between organic chemistry and chemical biology. We are focused on designing chemical transformations that are capable of modifying peptide medicines in aqueous environments. These aqueous reactions will be applied toward the development of (1) bioconjugation reagents, which enables the attachment of therapeutic cargo onto peptides, and (2) cleavable linkers, which facilitate the delivery and release of peptides in diseased cells. These interdisciplinary projects will not only allow students to contribute to the advancement of peptides therapeutics, but also expose students to current challenges in synthetic methods, bioorganic chemistry, and environmental sustainability.
