My research aims to understand the interaction between behaviour and evolution, both in pure and applied contexts. For example, I am interested in predator-prey systems between birds and insects and how they co-evolve. Adaptations of the colour patterns in the insects alter the decisions by the birds, and different predation strategies played by individual birds alter the selection pressures on the insects. This arms race between predators and prey offers me a perfect setting to investigate the co-evolutionary processes taking place as we watch.
On a larger scale, I am interested in the evolution taking place on islands. Once again using bird species as our models, we are building a detailed understanding of the morphological and behavioural changes, including changes in song, which are occurring among the birds found across an archipelago of islands in Indonesia. This will allow us to understand the evolutionary pressures on these birds and so gain a better understanding of the evolutionary processes leading to speciation.
I also have a research group investigating the behaviour of badgers, their ranging behaviour, diet, reproductive strategies and parasites in Ireland. Building a comprehensive picture of badger ecology in Ireland is important both for effective conservation of this secretive member of our fauna, and because they have been shown to act as a wildlife reservoir for tuberculosis in cattle. Our results are used to assist the Department of Agriculture (DAFM) in effective delivery of a TB vaccine to the badgers.
I have long been interested in using an understanding of animal behaviour to inform captive animal management, improving the welfare of animals in zoos and the success of release programmes and conservation.

Research currently underway:
- Ranging and dispersal studies on badgers through GPS tracking of a badger population, in association with DAFM and NPWS. (Aoibheann Gaughran)
- Analysis of the genetic inter-relatedness of badger social groups (Aoibheann Gaughran)
- Bait delivery trials for vaccine delivery to badgers (Dave Kelly)
- A survey of the micro and macro endo-parasites found in badgers across Ireland and how this differs between sexes and age groups. This is a collaboration with the Parasitology group, TCD (Celia Holland).
- A long term biogeography investigation in Indonesia, investigating the evolutionary changes occurring in the bird populations living on islands near Sulawesi. This project is partly funded by Operation Wallacea
- Song analysis looking for the very first stages of speciation in bird populations on Indonesian islands. This project is in conjunction with Prof. Harte’s group: Digital Media Systems, Electronic & Electrical Engineering, TCD.
- Investigation of the effect of group foraging on the expression of foraging strategies by sticklebacks.
