I am an Emeritus Professor of Microbiology in the Microbial Sciences Department, where I was formerly Head of Department.
Prior to joining the University, I worked in the Pharmaceutical industry (Pfizer and GSK).
I did my PhD with Alan Bull at the University of Kent on the physiology of Aspergillus nidulans in chemostat culture and my first degree (in Microbiology) at King's College London.
I currently carry out ad hoc projects for the University and BBSRC but my main professional activity is membership of the Advisory Committee on Novel Foods and Processes (ACNFP) of the Food Standards Agency. I have been a member for 10 years, having been seconded for the past three years to help to establish new post-Brexit procedures. My main contribution to the panel is to advise on bioprocess analysis, and genomic/bioinformatics driven evaluation of applications for marketing of novel food products in the UK.
