My background is in zoology and ecology although I have always been interested in science more generally. My research interests lie in understanding ecological systems or processes from an evolutionary perspective which I tend to approach using computational / mathematical models. Traditionally, ecology is the study of the interactions between living organisms and their environment. During my Phd I focused on understanding interactions between individual animals living in close proximity which are determined by their behavioural rules. These rules are functions both of an individual's genotype and the local physical/ chemical/ biological environment. I am currently working on a diverse range of systems including vulture foraging, anti-predator behaviour in bird flocks and generating new statistical models for re-constructing food-webs.

Project Title
 Linking ecological processes to community patterns using stable isotopes
From
2011
To
2015
Summary
Novel methods to quantify differences in community structure: development of stable isotope metrics in a Bayesian framework. There is an overwhelming need for the ability to accurately and rapidly quantify the trophic niches of species within their ecological communities. A holistic approach which takes account of the multidimensional and variable nature of interactions within and among species and with the wider ecosystem as a whole is required to meet this challenge. In recent years, stable isotope techniques have revolutionised the study of trophic ecology. However, although they also hold much promise for the elucidation and description of trophic structure, we lack the mathematical tools that will allow us to make quantitative comparisons of these structures. The main aim of this project is to develop novel methods for describing the structure of ecological communities. These "isotopic community metrics" will be based on established stable isotope methods (Layman et al 2007a, Layman et al 2007b), but will be underpinned by a statistically robust quantitative framework. The newly-developed models will allow us to compare different communities directly and in an ecologically relevant manner, for instance before and after a disturbance such as species invasion, eutrophication or climate change. Equally, the niche width of organisms is inherently tied to their diversification and ultimately their speciation, giving this project an additional evolutionary aspect.

Project Title
 The evolution and maintenance of cooperative behaviour
From
Oct 2009
To
Sep 2012
Summary
The evolution and maintenance of cooperative behaviour is central to our understanding of biological systems, from gene/protein interaction networks, to bacterial colonies, all the way up to complex societies such as human civilisation and its components such as financial markets. The fundamental challenge to understanding these systems is how cooperation emerges and is retained when evolutionary pressure will drive individual components to selfishly cheat on their honest counter-parts. Ultimately, such cheating or defection is predicted to lead to collapse and failure of the higher level functioning of the group. It is quite clear that human society has developed mechanisms such as judiciary concepts involving policing and punishment for keeping cheaters at a tolerably low level within the group. What is entirely unclear is how our society developed in the first place, or how apparently more primitive systems lacking higher level cognitive abilities or recourse to emergent legislative judiciary can moderate against invasion by cheaters. The main research method of this project will be the creation of detailed mathematical and computational models of cooperative systems. The models will be novel in their approach by combining artificial neural networks, game theory and genetic algorithms to determine the cognitive and/or non-cognitive requirements necessary for effective policing. The models will also incorporate spiteful interactions between individuals and differences in competitive abilities between these individuals to investigate how these factors affect cooperation. Supplementary to these models, public goods games will be carried out with students in order to elucidate the principles underlying cooperation and policing in financial markets in particular.

Project Title
 The Ecological Implications of Context Dependent Aggression in Urban Environments
From
Jun 2009
To
Aug 2009
Summary
Ecosystems across the globe are becoming progressively more urbanized (United Nations 2006), as humans present an increasingly formidable evolutionary force on the rest of the planet (Palumbi 2001). Therefore, the effects of urbanization are becoming increasingly important on a global scale (Grimm et al. 2008). Urbanization is known to have remarkable effects on ecosystem form and function, as well as on species' distributions and abundances (Alberti 2005; Shochat et al. 2006). Relatively little, however, is known about what effect urbanization has on the behaviors of interacting species. For example, urbanization is known to alter community composition through the introduction of new species (Holway & Suarez 2006), and such changes are in part due to the behavioural differences between species (Holway & Suarez 1999), yet there is no clear evidence for how urbanization affects the behaviours of species (native or exotic). This project used shore crabs (Carcinus maenas) as a model system in which to study the complex competitive interactions that arise in urban-like systems.

Project Title
 Individual and Group Aggressive Behaviour in Social Organisms
From
01/12/2008
To
31/11/2010
Summary
Aims 1) Develop mathematical and computational models to investigate how aggressive group behaviour during a competitive interaction between cooperative social organisms (e.g. ants) emerges from the information transfer between individuals using context-dependent behavioural rules. 2) Extend models to include social organisms with intra-group competing interests in addition to between-group competition (e.g. bumblebees). 3) Develop empirical laboratory and field experiments to test individual behavioural rules and mechanisms of information transfer, as well as model assumptions and predictions.

My broad research topic is ecology and evolution, and specifically theoretical ecology. I am interested in how interactions between individual organisms of the same and different species generate macroscopic patterns we observe as ecosystems or food-webs. I have a developed a research group that is a leader in quantitative ecology in Ireland and with demonstrable global impact and renown with a portfolio of highly cited research papers in top journals. Several graduates from my lab have set up their own successful groups as PIs in internationally recognised institutions. The current focus of my research is a four-year project funded by the Irish Research Council which aims to develop a new set of quantitative tools that will allow us to maximise our ability to monitor and predict the response of ecosystem food-webs to a world that is changing and ever more managed or impacted by societies. A food-web in some senses is simple: it describes how energy and biomass flows up from primary producers (plants) through to consumers and up to higher level predators. The challenge is to manage better these systems on which we rely for health and wealth. My project is developing dynamic mathematical models to generate food-webs of various structure and behaviour, and coupled with new statistical models that might allow us to monitor these systems in the real world. We have recently identified new links between empirical data and fundamental properties of food-webs that will allow us to change the way we monitor and manage ecosystems. I am currently using this new research momentum to help mentor new junior colleagues and to win further funding by using the outputs to solve real world problems in marine ecosystems with a particular focus on large marine predators and ecosystem based fisheries management.
