Siobhan is currently a Head of RVC Animal Welfare Science and Ethics group and Senior Lecturer in Animal Behaviour and Welfare Science. She specialises in social behaviour, learning and cognition, behavioural approaches to assessing sensory capacities and animal 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 main areas of research encompass human-animal interactions, sensory perception and cognition, evidencing and measuring emotional states, social behaviour and development and application of welfare assessment. Her work focusses primarily on farm and companion animal species and utilises a range of disciplines including behaviour, physiology and social sciences.
Her current and recent projects include
- “Envirobot: an autonomous roving platform for environmental, health and welfare monitoring of poultry.” Innovate UK (2019-2022)
- "Measuring and monitoring the welfare of hens in cage-free systems." Oaklands Farm Eggs (2019-2021)
- "Improving the welfare assessment of broiler chickens" Open Philanthropy\RSPCA (2018-2020)
- "Robochick: an automonous platform for data-collection in poultry sheds" Innovate UK (2018-2019)
Siobhan also currently supervises a number of Postgraduate students. Carlos Rebelos is investigating how electrical stunning of turkeys ducks and geese can be improved. Lola Brookes is investigating improvements in the welfare of amphibians used in research through refinement and replacement. Justine Pearce is investigating artificial intelligence-enhanced continuous monitoring of individual locomotor dynamics to detect changes in poultry behaviour, health and welfare. Lola Brookes is investingating how to refine, reduce and replace the use of non-model amphibians in experiments on amphibian infectious diseases to adress mass extinction.
Siobhan’s past students include: Jade Hall (graduating 2019) who investigated whether posture and movement of birds can reflect personality and affective state. Liane Preshaw (graduating 2018) who investigated development and validation of an equine welfare assessment protocol and equine euthanasia decisions. Sandra Sanchis Mora (graduating 2017) who investigated how diagnosis, monitoring and treatment of neuropathic pain in dogs can be improved. Emma Buckland (graduating 2015) who investigated objective indicators and human assessment of canine emotional states along with factors contributing to variation in their expression. Jen Jamieson (graduating 2013) who investigated knowledge attitudes and (consumer relevant) behaviour of adolescents with respect to farm animal welfare. Jen identified hitherto unrecognised key barriers to behaviour change essential to address as part of educational strategies. Her work was consulted for the FAWC Report on Education, Communication and Knowledge Application in Relation to Farm Animal Welfare (Dec 2011). Nick Gover (graduating 2013) investigated spatial and colour vision in chickens and how their visual abilities are affected by dim light (primary supervisor John Jarvis). Heather Morris (graduating 2007) investigated environmental management of injurious pecking in turkeys.
Siobhan’s previous research has investigated social behaviour and cognition in pigs and poultry (BBSRC Animal Welfare Initiative); visual perception in hens (BBSRC Animal Welfare Initiative); prioritisation of canine welfare issues (RSPCA); capacity of chickens to rationally discriminate future outcomes of choice using the self-control paradigm (BBSRC); gas stunning of poultry (Defra); development of a common currency welfare assessment for exposure to concurrent stressors (BBSRC); and welfare of deer during lairage and transport (SOAEFD).

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 working 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'.
Our group is utilising various advances in technology, machine learning and our knowledge of animal behaviour to further improve welfare assessments for a wide range of species.
An innovative approach to assessing animal emotional states which underpin animal welfare. Although we often consider facial expression the best indicator of emotion, humans convey information about their personalities and emotional states in their body posture and movements. Do animals do the same and can we objectively measure emotion in this way?
Welfare is about more than physical health, so we develop and test welfare assessment protocols to facilitate appropriate treatment and prioritisation of equine welfare issues. Our research has covered horses in England, including geriatric and rescue horses, as well as donkeys and mules in developing countries.
We aim to refine the way that animals are used in research. Our projects focus on humane husbandry: how best to identification-mark mice, how frequently to clean rat cages, and how to minimise harmful effects from strong odours in the lab, given rodents' extremely well developed olfactory senses.

Chickens are the world's most numerous captive species. This body of research aims to understand the - often complex - cognitive and perceptual abilities of chickens and learn more about their social lives by effectively asking them questions . This is crucial to discovering how husbandry and management can impact on chicken welfare as well as informing legislation and societal acceptability of welfare standards.
Precision Livestock Farming (PLF) systems or as they were previously called “Integrated Management Systems” aim to manage livestock farming by continuous automated real time monitoring/controlling of production/reproduction, health and welfare of livestock and environmental impact (after Prof. Daniel Berckmans, KU Leuven, Belgium).
We currently have a number of different projects investigating the welfare of a range of species during stunning, slaughter (with and without stunning) & euthanasia.
We run various projects on wild animals, ranging from great apes to sunbears. These include projects that form part of the MScs in Wild Animal Biology and Health. Our work also includes looking into ways wildlife is managed and control, including the asking questions on the the humaneness of different culling methods for 'pests'.
