RUBEL: Roehampton University Behaviour and Energetics Lab

I lead the Roehampton University Behaviour and Energetics Lab (RUBEL). My body of publications in the main covers four topics, all of which primarily concern vertebrate environmental physiology and energetics: the respiratory physiology, energetics and behaviour of ducks and cormorants; the relationships between the behaviour, ecology and energetics of wild diving king penguins; comparative analysis of diving and pedestrian locomotion across species, and the development of the 'accelerometry technique' as a method for quantifying behaviour and energy expenditure in terrestrial and aquatic animals.

A full list of my publications is available here - GoogleScholar and ResearcherID - access to the majority of them as pdfs can be found here - ResearchGate.

Short videos explaining some of the recent research articles I have (co)authored are available here:

New study shows Hammerhead Sharks swim sideways saving energy

A new study in the Department of Life Sciences has discovered that great hammerhead sharks swim whilst rolled onto their side, a technique that is more efficient than traditional upright swimming.
