My main research interests concern the evolution, ecology and conservation of marine and freshwater fishes. My research has a particular emphasis on using molecular methods to elucidate ecological and evolutionary processes including classical tools such as microsatellite markers and Sanger sequencing, coupled with next-generation sequencing. My evolutionary interests include polyploidy, speciation and mimicry particularly in Neotropical Corydoras catfishes. My more applied interests include fisheries induced evolution using the guppy as a model system, population structure and traceability of marine and freshwater fishes using SNP markers, predator/prey relationships using DNA based methods and conservation genetics of UK freshwater fishes.
