The influence of UV reflectance differs between conspicuous aposematic signals in Neotropical butterflies and poison frogs.

Research

Why do animals look and behave in the ways that they do?

How do individual differences affect how communities interact?

What can we do to protect biodiversity?

I am a Behavioural Ecologist currently working as a Postdoctoral Fellow in the Department of Psychology, Neuroscience & Behaviour at McMaster University.

My research is all about understanding and protecting biodiversity from the scale of individuals to ecosystems. I focus on dynamic behavioural processes and frequently use animal colouration to give insights into ecological and evolutionary trade-offs. I am particularly fascinated by amphibians and reptiles. Find out more here.

I am originally from Bristol (UK) and now find myself in Hamilton (ON, Canada).

I am lucky enough to work with some wonderful people around the world.

Animal Colouration

Animal Colours

Animals use colour in many different ways, but how do these colours work?

My research aims to understand how colours evolve and are perceived, for example:

Warning signals

Camouflage

Transparency

Mimicry

Communication

Predators & Prey

Predator-Prey Dynamics

Predators and prey must make life or death decisions everyday, but how do animals behave when under stress or when information is scarce?

My research aims to examine how animals ensure their survival via:

Decision making

Prey selection

Competition

Escape behaviour

The natural world is changing quickly, creating new challenges and opportunities. How do animals react to these altered landscapes and communities?

I am working to understand the importance of behaviour and biodiversity, as well as how we can protect ecosystem function:

Changing behaviour

Changing communities
