Stuart Graham Cull-Candy FRS, FMedSci (born 2 November 1946) is a British neuroscientist. He holds the Gaddum Chair of Pharmacology and a personal Chair in Neuroscience at University College London. He is also a member of the Faculty of 1000 and holds a Royal Society - Wolfson Research position.
He earned a MSc from University College London, and a PhD from the University of Glasgow.
After working as a Royal Society Exchange Fellow at the University of Lund with Prof Stephen Thesleff, he held a Beit Memorial Research Fellowship in UCL's Biophysics Department with Sir Bernard Katz and Prof Ricardo Miledi. He was previously a Wellcome Trust Reader and then Professor of Pharmacology. He has been an Editorial Advisor to Nature, and served on the Editorial Boards of various journals including Neuron, The Journal of Physiology and as a Reviewing Editor on Journal of Neuroscience. Currently he is a member of the Royal Society's University Research Fellowships Committee, and the Leverhulme Trust Senior Research Fellowships panel. He was awarded the GL Brown Prize by the UK Physiological Society, and was appointed a Howard Hughes International Scholar in 1993 (one of only 20 in the UK). He is a Fellow of the Royal Society, the Academy of Medical Sciences and the British Pharmacological Society.
His research focuses on understanding molecular and functional properties of glutamate receptor channels underlying fast synaptic transmission in the brain. His research activities also include the study of ionotropic GABA and glutamate receptor signalling and regulation of neurotransmitter release. He has been a keen advocate of patch-clamp recording techniques combined with molecular methods for investigating central synaptic transmission.
