An important goal of evolutionary biologists is to explain the acquisition and loss of novel traits, such as organs, structures, physiological processes and genes. Currently, my research involves evolution at the level of genes, either in regulation or function, which underlie important episodes of change in the evolutionary history of complex organisms. I am particularly interested in those traits that are under sexual selection, namely those involved in regulating physiological interactions between males, females, and offspring as a result of a species’ reproductive physiology and mating systems.In addition, research in my lab involves the use of molecular markers to examine the molecular ecology and systematic biology of a wide range of taxa.
