Investigator biography

Mike has spent most of his career in Cambridge. He was an undergraduate and postgraduate student at Trinity College (BA, 1976; Ph.D. 1979). He then worked for a short time as a post-doctoral research associate with Prof. Alan Cuthbert, FRS, before moving in 1980 to a Lectureship at the School of Pharmacy, University of London. He returned to Cambridge in 1984 to a Lectureship. He was subsequently promoted to Reader in 2000 and Professor of Molecular Pharmacology in 2009. He became Sheild Professor of Pharmacology in 2017. Mike has spent extended periods of research leave at Yale University and the University of Wisconsin, Madison. He has a wide network of collaborators within Cambridge, elsewhere in the UK, and in the US, Japan, Brazil, and Chile. He is a Fellow of Christ’s College. His research interest is in the imaging of biomolecules using atomic force microscopy.
