My lab focuses upon understanding the biological basis of individual variation in behaviour in general and aggression in particular. My work has examined how variation in aggression i) evolves, ii) is tied to genetic variation, and iii) is tied to brain structure and function. I have shown that models of aggressiveness predict individual differences in aggressiveness that must be set at an early stage in development if they are to be evolutionarily stable. In agreement with this, empirical studies suggest that adult variation in aggressiveness is organized by differing exposure to testosterone while in the womb.

我的实验室专注于了解一般行为和攻击性的个体差异的生物学基础。我的工作研究了攻击性的变化如何i）进化，ii）与遗传变异有关，iii）与大脑结构和功能有关。我已经证明，攻击性模型预测了攻击性的个体差异，如果它们要在进化上保持稳定，就必须在发展的早期阶段确定。与此相一致的是，实证研究表明，成年人的攻击性差异是由在子宫中时睾丸激素的不同暴露所组织的。
