I am a microbiologist, with broad interests in microbial ecology and evolution, particularly in regard to antimicrobial resistance (AMR). I am interested generally about the environments and contexts that promote selection and maintenance of AMR in bacterial communities. 

I am currently working as a postdoctoral researcher with Dr Aimee Murray, Professor Will Gaze, Professor Angus Buckling, Professor Mario Recker, and Professor Barbara Kasprzyk-Hordern to understand AMR evolution in the environment to improve environmental pollution policy. 

For my PhD I researched how non-antibiotic drugs could select for AMR in bacterial communities. This included investigating how pharmaceuticals such as painkillers, and natural hormones could lead to increased antibiotic resistance within bacteria at environmentally relevant concentrations. For this I worked with Dr Aimee Murray, Professor Will Gaze, and Dr Lihong Zhang from the University of Exeter, alongside supervisors Professor Barbara Kasprzyk-Hordern and Professor Ed Feil from the University of Bath. My project was co-funded by Astra-Zeneca, and was supervised by Professor Jason Snape.
