Research Interests
We study molecular and cellular aspects of G protein-coupled receptor (GPCR) signaling. GPCRs are the largest class of cell-surface receptors and are activated by a diverse range of ligands, including sensory stimuli, hormones, and neurotransmitters. They play crucial roles in cellular functions such as chemotaxis and synaptic plasticity, and are involved in virtually all physiological processes. Because of their importance, it is not surprising that GPCR signaling has been implicated in a multitude of human disorders (cancer, neurological disorder, metabolic disease, viral pathogenesis, etc.) and is the target of many therapeutic agents. Thus, understanding the signaling pathways at the molecular level is among the highest public health research priorities.
