Research interests

My interests lie in studying interactions between the genomes of organisms and their environment, focusing on three areas:-

  • How social, ecological, behavioural, host-parasite, climatic, structural and demographic/ temporal parameters shape the genome,
  • How these factors lead to epigenetic/genetic adaptations and their role in locally adapted traits,
  • The implications these have for the fitness of an individual/population/species, the mechanisms responsible for their persistence and ultimately how these lead to evolution/ speciation.


I teach on a range of courses in the School of Biosciences and Medicine at both the Undergraduate and Postgraduate levels.

My primary focus here at Surrey is developing courses/modules and student experience within the areas of Ecology and Zoology.

A general prediction of the neutral theory of evolution is that genetic diversity should correlate positively with effective population size. We show here that diversity across eight microsatellite loci was consistently and substantially lower in one common amphibian (Bufo bufo) than in another with similar life history traits (Rana temporaria) despite B. bufo having the larger breeding assemblage sizes. However, B. bufo breeding assemblages were much more highly differentiated than those of R. temporaria according to both Fst and Rst estimators. These differences occurred in shared habitats across identical geographical distances. The patterns of genetic diversity and differentiation detected in these two species were probably a consequence of high gene flow in R. temporaria but much lower gene flow among the larger but more dispersed B. bufo assemblages. These observations highlight the difficulty of defining the boundaries of wild populations, and show how two broadly similar species can exhibit very different population dynamics.
