Biography

Neil Oldfield obtained a BSc in Biological Sciences with Microbiology from the University of Warwick (1996) and a PhD in Molecular Microbiology from the Department of Genetics, University of Leicester (2000). After postdoctoral work at the University of Cambridge, he joined the Molecular Bacteriology & Immunology Group (MBIG) at the University of Nottingham. Neil is currently an Assistant Professor in Molecular Microbiology.

Neil has carried out studies on the veterinary pathogen Actinobacillus pleuropneumoniae to investigate novel vaccine candidates to protect against this organism. Furthermore, he has published on protein secretion and glycosylation in the enteric pathogen Campylobacter jejuni. A long standing research interest has been the molecular pathogenesis of, and host response to, Neisseria meningitidis. This involves investigations into vaccination, carriage epidemiology and virulence. His research also encompasses the molecular pathogenesis of Neisseria gonorrhoeae.

Expertise Summary

Neil Oldfield's main areas of expertise are in molecular microbiology, bacterial protein secretion and vaccines.
