Research Interests:

My research is concerned with the design, synthesis, and biological evaluation of ligands for their use as tools and potential analgesic agents at opioid receptors. We are particularly interested in mechanisms for the association of such ligands with opioid receptors. Of particular interest is the role of heteromerization of GPCRs in signaling.
