Liz worked in the private sector as a Senior Food microbiologist managing a small food testing laboratory after gaining her Applied Biology degree from Trent polytechnic  in 1991.  She then returned to Higher Education and undertook the unmissable opportunity to study for a PhD at the University of Wolverhampton. After completion of a her PhD and post-doctoral research on the antimicrobial action of plant extracts against Helicobacter pylori she established herself as academic member of the Biomedical Science and Physiology department.


During her years at the University of Wolverhampton she has actively contributed to the provision of the Biomedical Science and Human Biology awards at both BCS and MSc level.  She has extensive teaching experience across a diverse range of modules including delivery of theoretical, practical and research based modules.   In the last few years has also been a key member of the TNE development team delivering the Biomedical Science top up degree in Sri Lanka.


Liz has had a passion for developing employability skills in students and has been actively involved in fostering these skills throughout the student lifecycle. As a key member of the placement team for most of her lecturing career she has been actively involved in meeting with employers on a regular basis and helping with preparing and supporting students for placements.


Liz is also active member of the University of Wolverhampton Antimicrobial Research Development  (UWARD) group and is the lead academic in the area of plant antimicrobials.



  • Investigations of the antimicrobial activity of plant preparations against pathogenic bacteria.
  • Anti-virulence effects of plant extracts including activity against biofilms, toxins and motility
  • In vitro modeling of the environmental niches of selected pathogenic bacteria
