Rowena is currently a BBSRC Research Fellow, specialising in companion animal behaviour and welfare. Her broad research interest is inherited diseases in the dog, with her current research focusing on canine neurodevelopmental disorders and their impact on animal welfare.
EDUCATION AND EMPLOYMENT
Rowena joined the Royal Veterinary College as a PhD student in 2009, became a Postdoctoral Researcher in 2013, and was awarded a BBSRC Future Leader Fellowship in 2016.
Rowena's background is in animal behaviour and welfare, having graduated from the University of Bristol in 2009 with a BSc (Hons) in Animal Behaviour and Welfare (1st Class). Her PhD, awarded in 2013, focused on inherited disorders related to extreme conformation in dogs, and was supervised by Dr Charlotte Burn and Dr Anke Hendricks. Following that, Rowena worked as a lecturer (maternity cover) on the MSc Animal Behaviour and Welfare course at Queens University Belfast. In 2014 she returned to RVC as a postdoctoral researcher investigating canine epilepsy and its behavioural comorbidities in RVC's canine epilepsy research group, led by Professor Holger Volk until 2017.
Rowena plays an active part in the early career researcher community at RVC, having been on the executive committee of the Researcher Association since 2015 (2015-2016: Vice-President; 2016-2017: President, 2017-2018 Senior Vice President.

Rowena's broad research interest is canine health and welfare, focusing on inherited diseases and how we can improve their diagnosis, treatment and ultimately, prevention.
Epilepsy and abnormal behaviour
In her current role as a BBSRC Future Leader Fellow, Rowena is investigating idiopathic epilepsy, a complex chronic brain disorder that affects both humans and dogs. Although seizures may be the signature symptom of epilepsy, co-morbid neurodevelopmental disorders are commonly diagnosed in people with epilepsy including attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), which may indicate shared underlying pathophysiology. Using a combination of behavioural and cognitive assays, quantitative EEG and MRI techniques, Rowena aims to establish whether ASD and ADHD-like behavioural abnormalities occur as a co-morbidity of canine epilepsy, and where present, identify associated neuroanatomical and neurophysiological markers, and explore their impact on canine welfare.
Her collaborators for this work include:
Rowena currently supervises two postgraduate students:
- Dr Sarah Finnegan: PhD 2017-2020: Investigating the potential of non-invasive seizure forecasting in canine epilepsy (co-supervised by Dr Lucy Asher, Dr Monica Daley, Prof Holger Volk)
- Dr Amy Pergande: MRes 2018-2020: Owner decision-making in the treatment and management of dogs with idiopathic epilepsy (co-supervised with Dr Zoe Belshaw and Prof Holger Volk)
In her previous role she worked as a postdoctoral researcher in RVCs canine epilepsy research team with Professor Holger Volk,with projects including:
- Development of a canine epilepsy smartphone app RVC Pet Epilepsy Tracker
- Impact of anti-epileptic drugs on the behaviour and welfare of dogs with idiopathic epilepsy (with Luisa de Risio)
- Impact of epilepsy upon the stress physiology and behaviour of affected dogs and their owners (with Dr Rob Fowkes)
- Risk factors associated with remission from idiopathic epilepsy
- Effect of treatment (including novel medications and diet) on seizure control
Breed health and conformation related disease
Rowena’s PhD research centred around the health consequences of extreme morphology in dogs. Her research focused on disorders that are directly associated with conformation, specifically:
- Brachycephalic Airway Obstruction Syndrome (BOAS)
- Corneal disease
- Intervertebral disc disease
She has an ongoing interest in this area and continues to lecture around the UK to breed clubs on these topics and supervise undergraduate and postgraduate students in research projects in this area, with a particular focus on owner perceptions of disease, and breeder and buyer behaviour.

Rowena is involved in lectures and Directed Learning sessions related to animal welfare to the BVetMed, BSc and veterinary nursing courses. Rowena annually guest lectures for the University of Edinburgh's MSc in Applied Animal Behaviour and Animal Welfare, and co-supervises MSc thesis projects related to her research interests.
In 2013 she lectured Animal Welfare for a term (maternity cover) at Queen's University Belfast on their MSc Animal Behaviour and Welfare.
Rowena is currently recruiting for studies related to canine epilepsy, listed here:

A study to investigate the long-term influence of a medium chain fatty acid diet on canine idiopathic epilepsy - LifeTIME (Long Term remission Mct Epilepsy) study
Dietary management for epilepsy is commonly used in humans, and recent studies at RVC have demonstrated that a diet containing medium-chain-triglycerides (MCTs) can reduce seizure frequency, and improve behaviour in some dogs with epilepsy. The purpose of the present trial is to confirm the efficacy of an MCT enriched diet in the management of dogs with idiopathic epilepsy. We will use a parallel design, which means that your dog will either receive a standard high-quality diet or the same diet enriched with MCT.
Extreme body shapes can cause debilitating conditions, from breathing difficulties to agonising slipped discs, and from irritated wrinkly skin to eye ulcers. Our research highlights the need for breeding strategies that safeguard the welfare of these companion animals.
IDEAS (Idiopathic Epilepsy and Anxiety Study) - Investigating the relationship between epilepsy, drug-resistance and affective disorders in the domestic dog
IDEAS aims to investigate how environment, diet, genetics and other factors affect the development of epilepsy and anxiety, and how they may be linked in dogs with epilepsy. This study will improve our knowledge and ability to diagnose epilepsy and develop treatments for dogs with epilepsy. We aim to increase quality of life for both dogs with epilepsy and their owners. To do this we are specifically recruiting German Shepherd and Border Collies as both breeds are popular in the UK and have a breed predisposition for drug-resistant epilepsy.
PREDICT Study (Prodrome Recognition in Epileptic Dogs to Improve Control and Therapeutics) – Investigating the potential of non-invasive seizure forecasting in dogs with idiopathic epilepsy
PREDICT aims to investigate the potential of non-invasive seizure forecasting in dogs with idiopathic epilepsy. This study will improve our knowledge and ability in prediction of seizures and management of canine epilepsy. We aim to increase quality of life for both dogs with epilepsy and their owners. To do this we are specifically recruiting any breed, age and sex of dogs from the United Kingdom.
The Big Brainy Border Collie Study: Investigating brain structure, function and behaviour In Border Collies with and without Idiopathic Epilepsy
Epilepsy is a complex brain disease seen in both humans and dogs. Subtle differences in brain anatomy, electrical activity in the brain, and day to day behaviour are found between people with epilepsy and people with normal brain development. We are interested in exploring these differences between Border Collies with and without epilepsy, and if they may mimic differences seen in human epilepsy cases.
