Biography

I am interested in the behavioural biology of social living. I have a particular fascination with aggression, dominance, and sociality. I seek to better understand social behaviour through the integration of functional, developmental, and mechanistic approaches. I primarily work with fishes in my research, in particular the remarkably social, cooperatively breeding cichlids of Lake Tanganyika.

Areas of expertise:
• Agonism, dominance, and contest behaviour
• Cooperative breeding, sociality, and group living
• Neuroendocrine mechanisms of social behaviour
• Brain size evolution and plasticity
• Fish cognition and behaviour
