After graduating from the veterinary program at the University of Bristol, U.K., in 1991 with honors, Dr. Lascelles completed a PhD in aspects of pre-emptive/perioperative analgesia at the University of Bristol. After an internship there, he completed his surgical residency at the University of Cambridge, U.K., in 1999. He moved to Colorado for the Fellowship in Oncological Surgery at Colorado State University, then a period of research in feline pain and analgesia at the University of Florida, and is currently Assistant Professor in Small Animal Surgery with active clinical and research interests in acute and chronic pain. He organizes the Integrated Pain Management Service. He is board-certified in small animal surgery by the Royal College of Veterinary Surgeons, the European College of Veterinary Surgeons, and the American College of Veterinary Surgeons.
