Freddie is Head of the Anaesthesia and Analgesia Service. He graduated from Padova, Italy, and trained as a veterinary anaesthetist in the UK. He achieved European Specialist  status in Veterinary Anaesthesia and Analgesia in 2003. Anaesthesia, perioperative care, and analgesia have been his main interests since he was a veterinary student. He is particularly interested in the physiology and pharmacology of anaesthetics, sedative and cardiovascular drugs. After working as an Anaesthesia Lecturer in Padova he took up a post as a Clinical Anaesthetist in the UK and then spent 3 years working on a research project based at the University Division of Anaesthetics at Addenbrookes Hospital, This led to a PhD and he continues to collaborate in this project. He joined DWR in 2008 and has built an Anaesthesia Service to support the other Specialist disciplines. Freddie has developed clinical and research projects, many of which have resulted in peer reviewed publications. He contributes actively to continuing education in the UK and overseas; and is author of a handbook of small animal anaesthesia. Freddie has served as an officer of the European College of Veterinary Anaesthesia and Analgesia for many years and is currently its President.
