Research Statement

We are interested in the isolation and biochemical characterization of compounds that selectively act on the nervous system. These probes are used to study the structure and function of central nervous system receptors and ion channels in both health and disease states. Structure/function analysis of these ligands provides opportunity for drug development of selected compounds. Currently these compounds are being investigated for the treatment of chronic pain, epilepsy, Parkinson's disease and drug addiction.
