My research activities focus on combining evolutionary and genetic approaches to human behaviour. This involves experiments, twin studies, and statistical genetics. Broadly, I want to know what evolutionary processes gave rise to the various characteristics of our extraordinary species, and why there are wide, heritable individual differences in these characteristics despite selective pressures favouring only the most advantageous genetic variants.
I'm particularly interested in mate preferences and choices, physical/behavioural/brain masculinity-femininity, physical attractiveness (face and body), intelligence, personality, and sexual behaviour and orientation.
Current PhD students under my primary supervision are James Sherlock, Jo-Maree Ceccato, and Liza van Eijk. Dr Anthony Lee is a former student with whom I still collaborate. I work closely with Prof Bill von Hippel's research group here at UQ, as well as the Genetic Epidemiology Laboratory at QIMR Berghofer.
