Research Interests &  Current Projects


My research focuses on the evolution and ecology of phenotypic plasticity, particularly in reproductive strategies. When is plasticity adaptive, how does it evolve in different environments, and does it allow populations to track or adapt to changing conditions? I examine both the functional form of plasticity as well as the ecological and evolutionary consequences of plasticity in changing environments. I employ theoretical and empirical approaches to explore these questions, and focus on vertebrate study organisms. My main research foci are in the study of sex allocation in mammals and temperature-dependent sex determination, so I spend a lot of time thinking about sex ratios in long-lived vertebrates.

Topics of interest include:

  • Evolution and heritability of plasticity
  • Investment in sons vs. daughters in mammals
  • Allocation of resources into reproduction
  • Offspring size vs. number
  • Parental care
  • Physiological correlates of life-history trade-offs
  • Physiological mechanisms of sex allocation in mammals
  • Effects of incubation temperature on reptile sex determination and hatchling phenotypes
  • Thermal Ecology
  • The evolution of sex-determining mechanisms
  • Annual timing of reproduction in response to climate
  • Alterations in behaviour and reproduction under parasitic infection
  • Ecoimmunology and endocrinology

Students interested in pursuing an Honours or PhD in the above areas can contact me via email to discuss potential projects. I am especially interested in students with interest in working with my captive jacky dragon colony or conducting field work on mammals or lizards at one of UNSW’s field stations at Fowlers Gap or Smiths Lake.
