MVB BSc(hons) GPCert(SAP) GPCert(FelP) GPCert(Derm) GPCert(B&PS) PGCertVetEd FHEA MSc(VetEpi) PhD FRCVS
Associate Professor in Companion Animal Epidemiology

Department: Pathobiology & Population Sciences

Campus: Hawkshead

Research Groups: Animal Welfare Science and Ethics

Research Centres: Veterinary Epidemiology, Economics and Public Health

Associate Professor in Companion Animal Epidemiology and senior lead for the VetCompass Programme as a research and teaching resource. Dan’s role is mainly research-based within VetCompass, supporting Pandemic Puppies and contributing to many other research projects at RVC.

After graduating from Dublin Vet School in 1987, Dan worked in general practice and industry 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, general practice, feline practice, dermatology and business management. In 2009, he undertook an MSc and then a PhD in veterinary epidemiology at the RVC supported by the RSPCA that explored breed-related health in dogs and cats. During his PhD, Dan developed the project along with this PhD supervisors for large-scale collection of primary-care veterinary clinical data for research. Dan also developed many of the methods to investigate these data that are still used today. From 2013-2014, he undertook post-doctoral research supported by Dogs Trust to establish welfare scoring methods in dogs and further develop VetCompass. From October 2014-2017, Dan was the Kennel Club Charitable Trust Companion Animal Epidemiologist at the RVC and extended the data collection to also include veterinary referral, charity and emergency care. Dan was appointed as Senior Lecturer in Companion Animal Epidemiology in September 2017 and promoted to Associate Professor in 2021. In this role, he continues as senior lead on the VetCompass Programme where he collaborates with a wide range of undergraduate and post-graduate students as well as later-career researchers worldwide on VetCompass and linked studies covering the breadth of animal species under veterinary care. He has extended the geographic spread of VetCompass to Australia and Singapore, with several other countries aiming to come on board over the coming years. He also supports the application of VetCompass as a major tool for undergraduate and postgraduate teaching and learning at RVC.

Dan gained a PGCertVetEd in 2020. Dan was awarded a Fellowship of the Royal College of Veterinary Surgeons in 2018, the BSAVA - Blaine Award for Advancement of Small Animal Science and the RVC - James Bee Student Nominated Award for Outstanding Project Supervisor in 2019 and 2023, and the RVC - First prize for PGCertVetEd in 2020. In 2021, he was awarded the Kennel Club Charitable Trust ‘International Canine Health Award’, the All Party Parliamentary Group ‘Phillippa Robinson Dog Welfare Award in 2024, and the RCVS Impact Award in 2025.

In addition, Dan has chaired the UK Brachycephalic Working Group (BWG) since 2016 and is a founding member of the International Collaborative on Extreme Conformations in Dogs (ICECDogs), the Dog Breeding Reform Group (DBRG) and the Legal Advisory Group on Extreme Conformation in Dogs (LAGECDogs). He is a member of the RCVS Knowledge Quality Improvement board and the RVC Clinical Research Ethical Review Board.

Since 2011, Dan has authored over 160 peer-reviewed publications and co-written two books: Breed Predispositions to Disease in Dogs and Cats (2018) and Health and Welfare of Brachycephalic (Flat-faced) Companion Animals - A Complete Guide for Veterinary and Animal Professionals (2021).

Dan's research covers a diverse range of epidemiological studies based on primary-care veterinary clinical data collected via the . 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 primarily on improved understanding of the role of breed and conformation in relation to disorder prevalence and severity. In addition, Dan is involved in projects that also explore animal behaviour, drug usage, demography, longevity and welfare as well as human translational questions. As well as focusing on epidemiological questions relating to dogs and cats, Dan's work is increasingly extending to the full spectrum of species that are presented for primary veterinary care.
