Research interests

Our research revolves around the theme of drug discovery. Students can learn computer modeling techniques to identify compounds that are predicted to inhibit one of two proteins of interest: 1. CCR5 receptor (a protein involved in HIV viral infection of immune cells) and 2. Fatty Acid Synthase (an enzyme that catalyzes the synthesis of fatty acid and is upregulated in some cancers). In addition, we apply organic chemistry techniques to synthesize (solution and solid phase synthesis), purify (column chromatography, HPLC), analyze (NMR, Mass Spec, TLC), and modify the compounds of interest. We will collaborate with resident Biologists and Biochemists to test the efficacy of our promising compounds against CCR5 and Fatty Acid Synthase.
