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 Professor 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 in 2014 and is currently also the UFAW Link Representative at the RVC.
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.
Siobhan currently supervises a number of Postgraduate students. Jade Hall is investigating whether posture and movement of birds can reflect personality and affective state. Carlos Rebelo is investigating how electrical stunning of turkeys ducks and geese can be improved. Liane Crowther is developing a quality of life assessment for horses. Megan Vickers is improving our understanding of dogs' social communication and investigating what causes them to show aggression towards one another.
Siobhan’s past students include 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 currently teaches animal behaviour, welfare science and animal handling to undergraduates studying Biological and Bio-veterinary Sciences, Veterinary Medicine and Veterinary Nursing.
She is also an academic tutor for science and a postgraduate tutor and supervises a number of undergraduate and MSc projects annually.
She has a postgraduate certificate in Veterinary Education and is a Fellow of the Higher Education Academy.
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'.
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 movement. Do animals do the same and can we objectively measure emotion in this way?

Interpreting any animal's emotion correctly is key to safeguarding its welfare - and sometimes even our own welfare. Dogs are renowned for their 'human-like' expressiveness, but science can reveal which of their behavioural signals reliably discriminate between emotions such as anxiety versus pleasure, and which ones may be misleading.
This project aims to determine the role of the veterinary professional in detection and education of the DURC in both the UK and in Jordan as key case examples.
Pigs and poultry evolved to live in natural habitats which are very different to the environments in which they are frequently housed for farming. This body of work is made possible with our state of the art environmental control research facilities and engineering expertise. It focuses on the impact of artificial environmental husbandry factors on welfare, production and on impact on the external environment, which is critical for sustainability.
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.
At the Queen Mother Hospital for Animals we are conducting a study using sensory testing to establish if it could be a useful tool in the diagnosis and treatment of Nep in animals. This is a non-invasive and interactive study for both pets and their owners.

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.

The needs and views of Society dictate how scientific findings are implemented and what issues are investigated scientifically. Human attitudes towards animals can impact on their treatment and consideration as well as standards of welfare maintained.
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'.
