Biography

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:

Research interests

My present research quantifies the energetic costs for species in situations where energy expenditure can be high or highly variable. This line of enquiry is motivated by the theory that greater energy costs for an animal can have detrimental consequences for its reproductive success. I am therefore interested both in how animals are adapted to reduce energy costs to tenable levels, and the effects on reproductive fitness of fluctuations in an animal's energy costs. For example, I study the energy costs of arboreal locomotion in great apes and how they utilise the inherent elasticity in their environment to their energetic advantage. I also study how perturbations to the environment affect the foraging energy efficiency of seabirds from the UK to the tropics to the sub Antarctic, and in turn how this affects chick rearing during the breeding season. To support these research endeavours, I continue to be at the forefront of the development, validation and application of the accelerometry technique for estimating energy expenditure in the field.

Particularly for fieldwork but also for laboratory based studies, I consider the application of miniaturised data loggers to record key behavioural and physiological variables to be a powerful technique. I employ and develop, in particular, the use of acceleration loggers for recording both the behaviours and associated energetics of wild animals, mainly in collaboration with the groups led by:

Dr Susannah Thorpe, University of Birmingham

Dr Charles Bishop, Bangor University

Dr Jon Green, University of Liverpool

Dr Yves Handrich, CNRS Strasbourg

Prof. Rory Wilson, Swansea University

Dr Craig White, University of Queensland

Dr Shaun Killen, University of Glasgow

Research projects

I am presently involved in several on-going funded projects including:

- Savings the sea turtles of Anguilla: combining community action with scientific evidence to drive legislative change, funded by BEST EU

- Studying the behaviour, movements, macro-physiology and thus developing conservation management plans for seabird species inhabiting the Caribbean including the British Virgin Islands (funded by DEFRA Darwin Plus and the Leverhulme Trust) caribbeanseabirds.org.uk.

- Studying the costs of arboreal locomotion in tree-dwelling primates (NERC funded).

- Assessing the validity of using heart rate loggers and acceleration loggers to measure the costs of wing adornments in volant birds (Royal Society funded).

- On going development of a seabird field site on Puffin Island in Wales, primarily to study intra-specific variation in species exhibiting reproductive skew (Research at Puffin Island; internally funded - Roehampton and Liverpool).

Teaching

I am programme convenor for the UG and integrated Masters degree programmes in Zoology and Biological Sciences.

I presently teach on the UG modules 'Biometrics: Physiology, Statistics and Maths', 'Biosciences Research Methods' and the week-long 'Biosciences Field Course' based in rural Wales during late spring. I am also involved in teaching the integrated Masters module 'Current Topics in Biology'.

I supervise a number of second year project proposals, third year independent studies, and third year projects, which often review and research issues of energy expenditure in humans, diving behaviour in animals and various non-invasive physiological topics.
