University of Newcastle
Newcastle upon Tyne
I started my career as a clinical veterinarian and became involved in medical research at the Clinical Research Centre, London, while acting as their laboratory animal veterinarian. After completing a PhD in physiology, I moved to Newcastle, where I was able to develop my major interests in the science underpinning animal welfare.
Roles and Responsibilities
I am responsible for the overall management of the university research animal facilities. I am also the university "Named Veterinary Surgeon". I head a research group whose main objectives are strongly linked to improving the welfare of laboratory animals.

Welfare of animals used in biomedical research, and in particular issues associated with pain and distress. Comparative aspects of pain assessment and alleviation. Animal anaesthesia and the neurophysiogical effects of anaesthesia.
Our research group aims to develop improved methods of analgesia and anaesthesia for use in animals. We are also interested in comparative aspects of pain and analgesia. We also disseminate this information by developing training materials for research workers.
We aim to develop the comparative aspects of our research in pain assessment and alleviation. In particular, we are aiming to develop means of assessing the affective component of pain. We also aim to develop more humane methods of euthanasia of laboratory animals.
