I am a Microbial Ecologist in the Division of Biosciences, within the College of Health and Life Sciences at the University of Brunel London.
My research interests lie in the assessment of microbial community structure and function using high throughput sequencing and molecular microbiological techniques. My current research focuses on the gastrointestinal microbiome and changes as a result of disease or injury, this characterisation of the communities allows the identification of functionally important changes in microbial assemblages. My research has included work on the impact of stroke, brain injury, parasitic intestinal infections, and dementia on the interactions with the host and its microbiome.
My Doctorial training was in soil microbial ecology carrying out risk assessments and the efficacy of using bacterial biological control agents against fungi diseases of crops while at CEH-Oxford/Cardiff University. I then undertook postdoctoral research at The University of Sheffield followed by The University of Manchester continuing research into environmental microbiology. While at Manchester I moved into medical microbiome research as Researcher Co-Investigator on a grant on T. Muris and the impact on the microbiome and host. As a result of this I have formed a number of collaborations involving microbiome research.
