During his time at Oxford and in the early part of his time at UEA Geoff continued to work on cytochromes and together with Professor Graham Pettigrew (Edinburgh) co-authored two books on cytochromes c. His major research at UEA has been within the Centre of Metalloprotein Spectroscopy and Biology or its off-shoot, the UEA-Wolfson Molecular Structure Centre. In recent years his research has focused on the use of NMR spectroscopy to characterise proteins, and specifically their structure determination, intermolecular interactions and conformational dynamics, and structure-function relationships in protein antibiotics and proteins involved in bacterial iron metabolism. Geoff joined the UEA Learning, Teaching and Quality Directorate in 2000.
