As a clinician and academic, he has dedicated 27 years of his professional career to veterinary students and producers, and collaborated with national and European animal production associations. On the basis of this work experience and research, he has written numerous scientific and technical publications. In recent years, he has also edited several books and special issues on animal production and veterinary medicine for scientific journals.

George Stilwell

Worked as a practitioner mainly with farm animals for over 15 years before joining the Veterinary Medicine Faculty (FMV) in Lisbon, where he now lectures on Farm Animal Clinics and Deontology and Bioethics. He did his PhD on cattle pain management and is a Diplomate at the European College of Bovine Health Management (ECBHM). He leads the Animal Behaviour and Welfare Research Lab (CIISA-FMV). George has been involved in various European projects on ruminant health and welfare (AWIN, Anicare, BovINE) and in several EFSA working groups. He is a board member of the Portuguese Veterinary Council and has published more than 50 peer-reviewed papers and several books on farm animal health and welfare.
