Bioinorganic and Biomimetic Chemistry

The main focus of our research is to understand the chemistry and biology of naturally occuring and chemically modified metalloproteins (including selenoproteins) and to develop new approaches for modeling/mimicking the enzymatic properties with purposefully-designed small molecules. Our group is also interested in the design and synthesis of novel sulfur and selenium-containing compounds as inhibitors of thyroid peroxidase and lactoperoxidase. We employ spectroscopic, crystallographic and biophysical methods in combination with chemical synthesis to accomplish these objectives.
