Dan is Senior Lecturer in Companion Animal Epidemiology. He works entirely as part of the VetCompass Programme . His work focuses on generating a reliable evidence base that can support improved welfare in companion animal species. His research uses clinical data shared with primary-care and referral veterinary practices to investigate a wide range of health and welfare issues in companion animal species, with particular emphasis on the breed-related health.

After graduating from Dublin Vet School in 1987, Dan worked in general practice for 22 years, latterly running his own companion animal practice in Kent for 12 years. During these years, he has also gathered qualifications in pharmacology, feline practice, dermatology and business management. In 2009, he undertook an MSc and then a PhD in veterinary epidemiology at the RVC. His PhD was supported by the RSPCA and developed the VetCompass project collecting primary-care veterinary clinical data to generate evidence on breed health in dogs and cats. From 2013-2014, he undertook post-doctoral research supported by Dogs Trust to establish welfare scoring methods in dogs. From October 2014, Dan was the Kennel Club Charitable Trust Companion Animal Epidemiologist at the RVC. From September 2017, Dan has been appinted as Senior Lecturer in Companion Aniamal Epidemiology. In this role, he continues to work within VetCompass to expand data collection from vet practices and to apply these clinical data in a wide range of welfare-related studies, with particular emphasis on breed-related health. He co-ordinates the use of these VetComapss data for teaching and research purposes across a wide range of undergraduate and post-gradudate projects.

Dan's research covers a diverse range of epidemiological studies based on primary-care veterinary clinical data collected via the VetCompass Programme. His projects include studies based both at the RVC and a growing number of external collaborations both in the UK and internationally. His research focus is on improved understanding of the role of breed in relation to disorder prevalence and severity. In addition, Dan is involved in projects that also explore animal behaviour, drug usage, demography as well as human translational questions.
