Yair Ben Chaim is a senior Lecturer in the Department of Natural and Life Sciences at The Open University of Israel. He received his PhD from the Hebrew University of Jerusalem under the supervision of Prof. Hanna Parnas and Prof. Itzhak Parnas. Yair then did postdoc research at the lab of Prof. King Yau at the neuroscience department at Johns Hopkins Medical School, where he studied the signal transduction of olfactory receptor neurons.
Yair's research group employs molecular, biochemical and electrophysiological approaches to study the function of G protein coupled receptors and their regulation.
