Siobhan is currently a Head of RVC Animal Welfare Science and Ethics group and Associate Professor in Animal Behaviour and Welfare Science. She specialises in poultry behaviour, cognition and welfare.

Siobhan graduated from University of Newcastle in 1994 with a BSc in Animal Science and went on to complete an MSc in Applied Animal Behaviour and Welfare at University of Edinburgh (1995).

Siobhan’s PhD (University of Bristol, 2000), supervised by Prof Christine Nicol (University of Bristol) and Prof Christopher Wathes (Silsoe Research Institute) involved development of a common currency welfare assessment for exposure to concurrent stressors, using transport of poultry as a model. Siobhan subsequently joined Prof Wathes' research group as a postdoctoral researcher in poultry cognition, demonstrating that hens can show self-control and receiving the Worshipful Company of Poulters' 2002 Poulters' Prize for a significant contribution to the poultry industry by a young scientist.

In 2005 she joined the Royal Veterinary College (RVC) as a postdoctoral researcher and, via an RCUK Fellowship (2008), was appointed to an RVC lectureship in Animal Behaviour and Welfare Science in 2012. Siobhan was appointed Head of Group RVC Animal Welfare Science and Ethics in 2014.

Siobhan currently holds several external positions:

  • Council Member of Universities Federation of Animal Welfare and Trustee for the Humane Slaughter Association
  • Member of Science Advisory Board for the Dogs Trust internal research programme 
  • Member of British Hen Welfare Trust Scientific Research Committee
  • External Examiner University of Glasgow MSc Animal Welfare Ethics and Law
  • External Examiner University of Bristol BScVS

Siobhan's has general interest in developing and validating measurement of welfare across species, but her primary research interests lie in poultry behaviour, cognition and welfare; covering both fundamental and applied research..

Siobhan has a postgraduate certificate in Veterinary Education (with distinction) and is a Fellow of the Higher Education Academy.

She currently teaches animal behaviour, welfare science and animal handling to undergraduates studying Animal Biology Behaviour Welfare and Ethics; Biological and Bio-veterinary Sciences; Veterinary Medicine and Veterinary Nursing and she supervises a number of undergraduate and taught postgraduate projects annually.

She is also an academic tutor for undergraduates studying science and for postgraduate students.  


Siobhan is works closely with clinicians to further application of research and research findings to clinical practice.

Siobhan is also involved in public engagement activities, particularly engaging school children in animal welfare and behaviour science.

Her activities have included running masterclasses on recording animal behaviour and understanding animal welfare and public speaking on chicken cognition and behaviour. She has also run an event on chicken biology and welfare and food labelling (Inside Chicken Run), first developed as part of National Science Week 2009, sponsored by RCUK but has since been run at RVC several times very successfully, as well as by invitation at celebrity Jimmy Doherty's Science Festival during National Science week 2010. Siobhan and her student Jen Jamieson were runners up in the national BBSRC Social Innovator of the Year 2011 competition for this work. She was also central to a primary school Royal Society Partnership Project (2011) to inspire and engage the future generation of scientists using animal behaviour which involved training chickens.

In 2013 Siobhan presented her research ‘Do hens have friends’ at the Ignoble Awards Tour. She has been interviewed about chicken cognition on BBC World News (2013) and was involved in the 2010 BBC Scotland TV programme 'The Private Life of Chickens'.

  • Assessing and Improving Animal Welfare

    Genetics and management can greatly affect the welfare of farm, laboratory, companion and wild animals. We aim to improve animal welfare by understanding how human activities and management practices affect the welfare of animals that are kept, killed or otherwise impacted by humans. Comparative research can identify practices that generally elicit poor or good welfare outcomes, providing evidence that can be used to support initiatives to improve animal welfare. 

  • Development of welfare assessment protocols and technology

    Assessment of animal welfare is continually being improved using new insights in animal behaviour, non-invasive physiological methods, animal-environment interactions, and novel monitoring systems for animal responses and behaviours. 

    Some of our work aims to develop a more fundamental understanding of which measures (e.g. behaviour, activity, posture etc) should most appropriately be targeted with sensor technology. However, technology is not always feasible (or even desirable) in some sectors, so we develop welfare assessments that are valid and practical in whatever context they are needed and tailored to the specific welfare aim.

  • Ethics of animal use and management

    Animal welfare issues often arise when there are conflicts of interest between humans and animals. This poses challenges around whose interests to prioritise, and what actions can be taken to produce the best moral outcome. The needs and wants of human, animal, and even environmental stakeholders must be understood and evaluated to decide what is the right course of action, but different ethicists and stakeholders may disagree about the conclusions of any ethical analysis. For example, unnecessary suffering must not be caused to legally protected animals, but what counts as ‘suffering’, when is it really ‘necessary’, and which animals should be protected? Evidence must be gathered and some consensus must be agreed upon as to weight the different possible actions.

  • Fundamental understanding of welfare

    Animal welfare refers to animal feelings, health, and environmental suitability. These projects explore which animals are sentient and what feelings they have, and how behaviour, health, environments, and welfare interrelate. We use a wide range of techniques to investigate these fundamental questions, each of which is tailored to the particular hypothesis and species involved. Emotions are subjective (private) to the individual experiencing them, which makes them challenging to investigate scientifically. 

  • Humane slaughter

    Livestock and other animals are stunned and dispatch for slaughter, disease control and population management.

    The RVC has a well-established Animal Welfare Science and Ethics research centre and members of the team study methods of stunning and dispatch of a variety of species in a variety of settings. The research is designed to help systems evolve and become more humane and less stressful for animals.

    The research is shared with stakeholders, which enables them to make scientifically informed changes that reduce animal distress.
