Research Interests:  Bioorganic Chemistry, Medicinal Chemistry, Supramolecular Chemistry, Synthetic Organic Chemistry

My research focuses on addressing biological problems using organic chemistry. One such project involves the synthesis of compounds that bind and transport anions across phospholipid membranes.  Transmembrane transport of anions is of great biological importance, as defective anion transport has been linked to numerous diseases, most notably cystic fibrosis. The goal of this project is to develop receptors that can bind and transport anions across phospholipid membranes to function as potential therapeutics for cystic fibrosis and other anion transport diseases.
