R. John Ellis

Reginald John Ellis (born 12 February 1935) is a British scientist.

Early life and education
Ellis was educated at Highbury Grammar School, London. He studied at King's College, London and obtained a BSc degree in 1956 and PhD in 1960, for thesis research on the enzymology of transamination. He was supervised by Professor D. D. Davies.

Career
Ellis became scientific officer in the ARC (Agriculture Research Council) Unit of Plant Physiology, Imperial College, University of London, 1959–61 and an ARC Research Fellow at the Department of Biochemistry, University of Oxford, 1961–64, working on the regulation of bacterial sulphate reduction with Professor C. A. Pasternak.

In 1964, Ellis joined the University of Aberdeen as a lecturer in the Department of Botany, and moved to its Department of Biochemistry in 1968, following a visiting professorship in the University of Toronto in 1967.

In 1970, Ellis moved to the newly created Department of Biological Sciences, University of Warwick, as senior lecturer and founding head of the Chloroplast Research Group. Ellis has remained at Warwick University as reader (1973), holder of a personal chair (1976), and emeritus professor (1996). He was a visiting professor at the Department of Chemistry, University of Oxford from 1996 until 2000. From 1990 until 2009, he organised annual meetings of the UK Molecular Chaperone Club at the Universities of Oxford, Cambridge, London, Bristol, Birmingham and Warwick.

Ellis is the author of How Science Works: Evolution.
