Bio

The extracellular space is a dynamic environment wherein vital signaling takes place. It also hosts biomolecules that serve as current and potential biomarkers for disease states. Our research seeks to uncover the molecular players connecting metal micronutrients and metabolic function in this extracellular milieu. Our approaches and strategies sit at the interface of bioinorganic chemistry, analytical chemistry, chemical biology, metabolic biology, and soil chemistry. Our lab has a specific interests in the interplay between first-row d-block transition metals and hormone function, with longstanding goal of extending our insights to develop therapeutic and diagnostic solutions to endocrine disorders spanning diabetes, liver disease, and cancer. Additionally, we have begun investigating the role of metals and metal-modulating metabolites in the plant rhizosphere with a specific interest in soil-borne polyphenols.
