Rapid infectious disease and foodborne pathogen diagnosis/detection

I gained my B.Sc. in Microbiology, M.Sc. (Res) in infectious diseases molecular diagnostics and Ph.D. in molecular diagnosis of bacterial pathogens in food all at the National University of Ireland Galway (NUIG).  I stayed at NUIG for my first post-doc, continuing in food microbiology research. This was followed by a two-year stint in industry (Beckman Coulter) developing real-time PCR based molecular diagnostics assays for infectious diseases including Mycobacterium tuberculosis.

I then returned to academia, taking up a post-doc position at University College London on TB diagnostics. In January 2013 I was appointed Lecturer in Medical Microbiology at UEA and was promoted to Senior Lecturer in August 2016.

I joined the Quadram Institute as a Group Leader in April 2018 while maintaining my affiliation with the University of East Anglia (UEA). My research continues to focus on the molecular diagnosis of pathogens with the aim of translating this research broadly, in different sectors and diseases, to maximise community/patient benefit.
