Professor Angela Webster
Angela is Professor of Clinical Epidemiology at the University of Sydney, and a senior Nephrologist and Transplant Physician at Westmead Hospital in Western Sydney. Working with people waiting for transplants and contributing as a special advisor to the organ donation services in NSW spurred her on to form CODE with her close colleague Kate Wyburn. In forming CODE, they established a collaborative network of people with interests in organ donation and transplantation, with the aim of delivering targetted research to improve service delivery. Angela is passionate about integrating patient values and preferences into health services research, and on supporting policy with relevant evidence. She prioritises research translation so that meaningful benefits are felt by patients and clinicians. Angela manages the CODE team.
