Associate Professor – Organic & Bioorganic Chemistry

Research and/or Creative Works

Research in our group spans the sub disciplines of synthesis and bioorganic chemistry and capitalizes in the synergy between the two areas. Our projects span a range of projects from the synthesis of peptide mimics, to proteomic approaches to the identification of protein-protein interactions, to development of methodology for the synthesis of combinatorial libraries to development of new synthetic methods. The synergy between bioorganic chemistry and synthesis is a strength of our program. For example, our peptidomimetic approaches are well grounded in organic chemistry principles such as conformational analysis and synthesis while often peptidomimetic targets necessitate the need for new synthetic methods and incidental chemistry inspires new synthetic methods.
