After nearly 10 years (May 2010–December 2019) of distinguished service as Editor-in-Chief of Molecular Imaging & Biology (MIB), Dr. Raymond Gibson (Fig. 1) has decided to step down and pass the baton. Dr. Gibson trained in organic chemistry and medicinal chemistry and undertook an NIH post-doctoral fellowship to conduct studies on the nicotinic acetylcholine receptor. The studies he initiated on the muscarinic receptor while at George Washington University led to the development of 4-[123I]Iodo-QNB, which provided the first images in humans of the receptor distribution in healthy individuals and those with various CNS disorders. He co-founded the Society of Non-invasive Imaging in Drug Development, and spent 20 years at Merck Research Laboratories, where he helped develop and characterize imaging probes for the NMDA receptor, the angiotensin receptor, endothelin receptor, CCK-A receptor, NK1 receptor, NPY-5 receptor, mGluR5 receptor, and CB1 receptor.
