John Hancock has worked in the area of cell signalling for over 30 years and on ResearchGate has over 170 research items listed. He has already authored a major textbook called Cell Signalling (now 4th ed.) published by OUP. Having studied for a BSc in Biochemistry he stayed at the University of Bristol, completing his PhD before remaining in the same department as a researcher for six years. In 1993 he took a post at the University of the West of England, Bristol, where he has remained ever since, being promoted to professor in January 2016. He has researched extensively on redox signalling in a range of organisms and has taught cell signalling to undergraduates and postgraduates for the last 25 years. He regularly attends and contributes to international conferences on nitric oxide signalling and the role of reactive oxygen species on biological systems, as well as writing numerous reviews and book chapters.
