I have dual interests as a historian and a critic of architecture. I trained originally as an architectural historian and have practiced as such over many years, focusing on twentieth-century housing. Later I became also an architectural critic and editor, co/editing the monthly review Architecture Today from 1989 to 2005 and chairing design review at CABE from 2010. These twin interests, in history and design, informed my work as an educator, from 2005-10 as head of the architecture school at Oxford Brookes and from 2011-15 as inaugural James Stirling Chair of Architecture. Since becoming emeritus professor in 2015, I have maintained these twin interests, publishing in 2017 Cook's Camden: The Making of Modern Housing (the result of ten years of research) and continuing an active involvement in design review and criticism, as a founding member of the Oxford Design Review Panel (2014- ) and elsewhere.
