Overview

My broad research interest is in social behavior, how the interactions between individuals combine to affect their fitness and life-history. From ants to human’s individuals interact in complex social systems, these social systems can have important effects on an individual’s behavior, and their ability to survive and reproduce. I’m interested the interaction between these broad global effects, the behavior of individuals, and evolution.

Since May 2020 I have been a Leverhulme Early Career Research Fellow in the Department. My fellowship focuses on understanding the links between social behaviour and life history evolution in whales.

Broad research specialisms:

Social behaviour, animal behaviour, behavioural ecology, network analysis
