I have a background in Biological Sciences: BSc (Hons) Ecology and Conservation at the University of Sussex and MSc Palaeobiology at the University of Bristol. I also worked as a research assistant at the Harrison Institute of Biodiversity and Research, studying the systematics and distribution of bat species.

In 2000, I trained with the Forensic Science Service (FSS) in London as a Body Fluids and DNA Reporting Officer. I held the position of Senior Forensic Scientist and worked on hundreds of body fluids and DNA cases. My role comprised:

case assessment,
examination strategies,
examination of items for body fluids and fibres,
blood pattern analysis,
evaluation of body fluid examinations;
interpretation of DNA profiles (including complex mixtures),
preparation of written statements and attendance at court as an expert witness.

I joined the University of Winchester in September 2018 as a Lecturer on the BSc Forensic Investigation programme in the Department of Applied Social Sciences, Forensics and Politics. I am module leader and lecturer on a number of modules including Practical Skills, Crime Scene Investigation, Biological Evidence and Forensic DNA Evidence.
