Talks and Interviews


Outreach interests

Madeleine is particularly interested in widening access to the BVetMed and BSc courses. She devised and taught a section on veterinary and animal ethics for the RVC summer school in 2018, and, via her role as a governor at Alleyn's school, is planning to work with a London Academy on access issues.

  • Ethics of animal use in competitive sport

    People: Madeleine Campbell

    Public concern about welfare issues relating to the use of animals in sport – particularly horse and greyhound racing – has increased in recent years. This area of research investigates whether there is an ethical alternative to abolishing the use of animals in sport.

  • Ethics of evidence based veterinary medicine

    People: Madeleine Campbell, David Mills, Adrian Boswood

    Evidence based veterinary medicine (EBVM) has the potential to make a significant contribution to improvements in veterinary and human health. However, unless they are addressed, hitherto under-explored ethical and societal dimensions to EBVM will limit this contribution. Madeleine Campbell and David Mills are working to elucidate such ethical and societal issues, and propose possible solutions to them.

  • Veterinary Ethics and Law

    People: Madeleine Campbell

    Madeline Campbell is leading projects on an ethicolegal review of the Dangerous Dogs Act and study looking into ethical aspects of the role of veterinary surgeons and veterinary organisations in addressing brachycephalia in companion animals
