(I am now a member of the Fraser Lab at the University of Exeter -

My interests are in the use of molecular ecology and population genetics in understanding how species adapt to novel environments, particularly in a conservation and management context. I am especially interested in the use of genome-wide signals generated by next generation sequencing applications.

Current research

Many rivers in southwest England have high levels of toxic metals due to a long history of mining in the region. Metal naïve fish do not fare well in such waters and yet many of rivers harbour apparently healthy and numerous populations of brown trout (Salmo trutta L.). I am undertaking genetic analyses to uncover the adaptive traits associated with the metal tolerance ecotype using microsatellites, RADSeq and RNASeq.

Previous work
I used microsatellites to characterise the genetic diversity of two Polish populations of the natterjack toad (Bufo calamita), supervised by Professor Trevor Beebee. My results were consistent with previous studies, confirming that B. Calamita
survived in an ice-age refugium in Iberia, from which the population dispersed in a leptokurtic fashion, spreading north and east during the last interstadial.
