About

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. In the past I have also written occasional papers on subjects outside of this field such as on facial asymmetry perception and the high noise to signal ratios of football matches. 

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 - and here - Academia.edu.

Research interests

My present research takes a comparative approach in seeking to quantify the energetic costs for species in situations where energy expenditure can be affected and have marked consequences for fitness. For example, the comparative costs of terrestrial locomotion in animals; putative changes in the energy expenditure of people dependent on whether they fast through the morning or not; the calories expended by king penguins while walking; the energy costs for primates of using different methods of arboreal locomotion; associations between reproductive success and foraging energetic efficiency in seabirds.

Fundamental to such questions is trying to understand the variability in behavioural and physiological adaptations of animals, including humans, in two respects. First, in terms of adaptive plasticity to a changing environment, where habitat changes occur both due to seasonal fluctuations, and due to year on year variations as a result of human influences. Second, in terms of variations in adaptiveness and perhaps ultimately, therefore, reproductive success between individuals within a population. Behavioural, physiological and energetic measures in combination enable me to answer fundamental questions about the plasticity of animals and humans.

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

Membership of professional bodies

I am a co-opted member of the Animal Section of the Society for Experimental Biology.
I am an honorary fellow of the Centre for Ornithology at the University of Birmingham.

Teaching interests

I am programme convenor for the degree programmes Zoology and Biological Sciences.

I teach on the UG modules 'Physiology and Introductory Statistics', 'Biosciences Research Methods;, 'Animal Biology I', 'Animal Biology II' and the week-long 'Biosciences Field Course' based in Wales during late spring. I am also involved in teaching the Masters modules 'Ecological Methods and Practice', 'Research Methods in Biology', 'Health Research Methods' and 'Obesity: Risks and Prevention'.

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.
