I currently demonstrate in the laboratory sessions of the Biomedical Science and Healthcare Science programs. Having completed my BSc. and MSc in Biomedical Science at Cardiff Met (formerly UWIC), I am able to assist laboratory sessions across a range of disciplines, although it is primarily microbiology. ​


am currently undertaking a funded PhD in Microbiology entitled "Assessing phenotypic and genotypic variation of small colony variants of Pseudomonas aeruginosa in a polymicrobial environment" between 2014-2017. The primary supervisor for this project is Dr Sarah Maddocks (Department of Biomedical Science). My secondary supervisors are Dr Kevin Purdy (University of Warwick) and Dr Nicholas Tucker (University of Strathclyde).

Previous research projects have been entitled:

"The Effects of Honeys on Pyocyanin and Pyoverdine Production in Pseudomonas aeruginosa" (2012-13) - supervised by Professor Rose Cooper

"Variation Between Strains Of Lactobacillus casei As A Probiotic Organism" (2013-14) – supervised by Dr Anna Dorel and Dr Sarah Maddocks. ​
