Research Interests

An Alternative to Lewis-Acid CatalysisMutagenesis studies have implicated an aromatic stack as the method of enzymatic activation for the purine salvage pathway in protozoa. Generation of a beta-haripin peptide with diagonally displayed tryptophan residues should mimic the binding pocket yielding glycosidic bond hydrolysis of adenosine

Peptides Mimicking Nature: The Crucial Role of Aromatics

The widespread use of pentachlorophenol (PCP) has resulted in this toxin leaking into the soil and ground water. By using a beta-hairpin scaffold a molecular cleft is engineered to bind PCP. These peptides may be tuned both structurally and electronically to bind additional, related toxins.

Biocatalytic Desulfurization of Diesel Fuel

The burning of sulfur containing compounds in petroleum fuel stocks has been linked with acid rain and cardiopulmonary disease. Bacteria degrade dibenzothiophene (DBT), but not on the macroscale. Introduction of aromatic rich peptides have shown the capacity to bind DBT and may present a novel method of sulfur removal.
