I joined the Dental School in Sheffield in summer 2007, returning after an absence from Sheffield of nearly 10 years to take up a lecturership in microbiology. My BSc (1st class, honors) was gained from Sheffield in Microbiology and Biochemistry. After which, I gained a PhD at the University of Warwick investigating the molecular mechanisms of methane oxidation in environmental bacteria. In 2002 I joined the Department of Pathology at the University of Cambridge investigating various aspects of flagellar biogenesis in enteric bacteria. This allowed me to develop an interest in protein secretion and the molecular pathogenesis of disease causing bacteria.
My main interests lie in the molecular level understanding of microbes, microbial disease processes and exploitation of this knowledge for improvement of health or commercial translation. The main areas include research on periodontal pathogens, host-pathogen interactions, Industrial Biotechnology and microbial glycobiology. I teach Medical and Oral Microbiology in the Dental School and across other departments at undergraduate and postgraduate level and also supervise a range of research projects at all levels.
- Research interests
The Group takes a multidisciplinary approach to investigating a range of biological problems ranging from basic biology to prototype translational projects. There are several areas of research within the group which centres around the study of bacteria with an overall aim at understanding microbial disease processes and exploiting the knowledge we generate for translational purposes wherever possible.
Periodontal pathogens: We focus on Gram-negative anaerobic species, mainly Tannerella forsythia and Porphyromonas gingivalis that are involved in the common disease periodontitis, estimated to affect 700 million people worldwide. However, most of the processes that we study in these bacteria are relevant to a range of human pathogenic bacteria with wide-ranging microbiological implications. For example, we have focused on the role of glycans at the host-pathogen interface revealing novel aspects of pathogen biology that has generated novel antimicrobials lead. This work involves molecular, biochemical and structural biology of bacterial enzymes, some of which have novel properties that have begun commercialisation.
Industrial Biotechnology: Our other main focus is in the developing area of Synthetic Biology where we are working to exploit biotechnological possibilities utilising biological knowledge of bacteria with a particular focus on protein secretion systems.
The group works in collaboration with colleagues in the Department of Chemical and Biological Engineering and Molecular Biology and Biotechnology (MBB) and with commercial partners when appropriate and currently have fruitful links with Ludger Ltd, GSK, Blueberry Therapeutics, Phytoquest and Fujifilm Diosynth Biotechnologies.
