Dr. Katz is a world-recognized leader in the field of pain, known for his ground-breaking research in phantom limb pain, pre-emptive analgesia, and transitional pain medicine. He is a Distinguished Research Professor of Psychology at York University, Professor in the Department of Anesthesiology & Pain Medicine at the University of Toronto, and Research Lead of the Transitional Pain Service in the Department of Anesthesia and Pain Management at the Toronto General Hospital. He is the inaugural Editor-in-Chief of the Canadian Journal of Pain, the official journal of the Canadian Pain Society.

Dr. Katz's program of research explores factors responsible for the transition of acute, time-limited pain to chronic, pathological pain after major surgery, including cancer-related procedures and transplant surgeries. He is evaluating interventions, such as specialized yoga programs, clinical hypnosis, and other mind-body treatments to reduce acute post-operative pain and prevent the transition to chronicity.
