Research interests                       
My general interests are in sexual selection and evolutionary/physiological ecology. I am particularly interested in testing how life-history trade-offs affect fitness, especially with regard to whole-organism performance capacities. By studying performance within a quantitative-genetic/life-history framework, my current research aims to understand how fitness is affected (and determined) by the genetic and phenotypic relationships among performance and other important life-history traits, such as sexual attractiveness, in different selective contexts. My recent collaborative work has also examined aging and the life-history factors affecting it in insects. Other research interests include:
  • The ecology and evolution of sexual dimorphism
  • The evolution of sexual signalling
  • The life-history of whole-organism performance
  • Anolis functional and evolutionary ecology
