Background
Howard was born in County Durham in 1951 and attended Washington Grammar School. After degrees at the Universities of Cambridge (MA, St Catharine's College) and London (PhD, Westfield College), he carried out research at the ICI Corporate Laboratory in Cheshire before moving to Manchester University in 1994 as a Royal Society Industry Fellow. He was Professor of Inorganic Chemistry at the University of Salford from 1997 to 2000, before taking up the Chair of Materials Chemistry at the University of Reading.Awards and honours
Awards for his work include the RSC Medal and Prize for Materials Chemistry (2006), a Royal SocietyLeverhulme Senior Research Fellowship (2007), the Wilsmore Fellowship of the University of Melbourne
(2007), the degree of Doctor of Science (ScD) of the University of Cambridge (2008), the MacroGroup UK
Medal for achievement in polymer science (2012), and a Royal Society Brian Mercer Award (2013).
Howard retired in December 2018 and was awarded a Leverhulme Emeritus Research Fellowship, based in
the University of Cambridge, where he worked from 2019 to 2020.
