Hello! I am a behavioural biologist based at the School of Biological Sciences, University of Bristol.

I hope you enjoy browsing the website, finding out about the exciting questions we ask and study systems we work on.

If you would like to know more or would like the opportunity to work with us, don’t hesitate to get in touch.

One main theme of our research concerns the behaviour and vocalisations of social animals. Using a combination of observational data, sound recordings and a variety of experimental manipulations, we work on several different bird, mammal, fish and invertebrate study systems in captivity and around the world (South Africa, Australia, Panama, Trinidad), including the Dwarf Mongoose Research Project which we established in 2011. We are also now starting to work with robots!

The second major theme of our research concerns the potential impact of anthropogenic noise. Using a combination of laboratory and field experiments (in Scotland, France, French Polynesia and Australia), we are considering how this global pollutant affects the behaviour, physiology and development of a variety of fish and invertebrate species.


We are extremely grateful to the following for funding:

    If you are interested in potential PhD, Masters or intern opportunities, then please feel free to email through a cover letter and cv. Specific projects will be advertised here when available; self-funded applicants welcome to apply any time.

    We are always keen to host fellows (those funded by Marie Curie, NERC and the Swiss National Science Foundation have recently finished their fellowships with us) or to discuss new collaborative ideas, so don’t hesitate to get in touch.

    We often take on research assistants to help with our work, including at various fieldsites and in the Bristol-based aquarium facility; specific positions will be advertised here.
