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.

My current work focused on social behaviors in Killer Whales working with Darren Croft. Using data from a 40 years of observation in we’re investigating in how the complex social systems of Killers Whales affect their behavior and survival. We are also interested in post-reproductive lifespans in Killer Whales and other animals.

Social behaviour, animal behaviour, behavioural ecology, network analysis
