My interests are in the use of evolutionary genetics in understanding how species adapt, particularly in a conservation and management context. I am especially interested in the use of genome-wide signals generated by massive parallel sequencing applications (WGR, RADseq and RNAseq).

I am currently a research fellow in the Fraser Lab working on a NERC-NSF funded project investigating the ecological genomics of adaptive polymorphism in the Trinidadian guppy (Poecilia reticulata).

I completed my PhD at the University of Exeter, where I investigated aspects of local adaptation in brown trout (Salmo trutta L.)  to toxic metal pollution in Southwest England. I used a combination of genetic (microsats), genomic (RADseq & RNAseq) analyses, and physiology experiments to uncover the adaptive traits associated with metal tolerance. My PhD was supervised by Dr Jamie Stevens and Dr Eduarda Santos.

After my PhD, I worked on the tail-end of a Leverhulme Trust funded project assisting in the development of a rapid diagnostic test for Bd detection in amphibians using lateral flow technology. This project was in collaboration with Dr Michael Dillon, Dr Jamie Stevens, Prof Chris Thornton (Exeter), Dr Andrew Bowkett (Whitley Wildlife Conservation Trust and Paignton Zoo).

I am a reviewer for Ecology & Evolution, Evolutionary Applications, Molecular Ecology, Molecular Ecology Resources, and Gene.
