Research interests

We study how G protein coupled receptors, like cannabinoid or bitter taste receptors are involved in normal functions or disease states. Signaling from GPCRs is involved in many different physiological processes and therapies, and our goal is to understand the effect of different drugs, like cannabinoids present in Cannabis, on various signaling pathways. We try to understand how different ligands induce different responses, and how this will influence normal functions or disease progression. One of our goals is to identify new targets to help in cancer therapy including cancers that are resistant to chemotherapy.
