My principle research interests lie in exploring the maintenance of adaptive variation in wild populations and, more specifically, the role of habitat variability in driving genetic diversity. A major theme of my recent research is understanding the immunogenetic basis of individual fitness in non-model organisms. Further to this I have explored, in collaboration with reproductive biologists and physiologists throughout Europe, the link between mitochondrial function, oxidative stress, and male reproductive success.
Currently I am interested in population-level responses to a changing environment. The ability of species to track their preferred habitat or, alternatively, to adapt to novel conditions will determine how the ecological landscape evolves in the face of human-induced climate change. In a collaboration with Flinders University in Australia we are using an ecologically important species group, the Australian rainbowfish, to investigate the effect of changes in climate and habitat on expression patterns of functionally important genes.
The study system comprises a powerful set of replicated populations of well-characterized rainbowfish phenotypes (i.e. ecologically distinct populations) shaped by natural selection. Next generation sequencing and high-throughput molecular genetic approaches are being combined to map the distribution of genome-wide adaptive variation in wild populations and to monitor the regulation of expression of key genes under different laboratory-controlled scenarios of environmental change. We will integrate these two complementary data sets to clarify the genetic basis of adaptation to different environments and to assess whether environmental changes predicted for Australia should exceed the adaptive capacity of populations of this ecologically important group of organisms.
