Oliver Ernst researches the receptors that are used in human nerve cell communication to send signals across membranes and control many functions, including vision, memory and learning. He is an expert on G-protein-coupled receptors (GPCRs), especially rhodopsins, a protein family in the retina of vertebrate animals that can detect visible and UV light. Using various spectroscopy techniques and X-ray crystallography, he works to understand the mechanisms of how these proteins interact with signal proteins, and the structures of GPCRs and rhodopsins in their inactive and active states.
