Andrew Walker developed an early interest in patient care during his undergraduate studies in Psychology at the University of Nebraska, where he focused on mental health, depressive disorders, and substance addiction. He subsequently joined a neuroscience laboratory at the University of Nebraska, researching the neural circuits involved in addiction and anhedonia.
In 2011, Andrew relocated to Melbourne to undertake his PhD at The Florey Institute of Neuroscience and Mental Health (University of Melbourne). His doctoral research continued to explore reward‑seeking behaviour using pre‑clinical models to better understand the neural circuits underlying motivation and mental health.
Andrew transitioned into clinical research in 2017, beginning as a Clinical Research Coordinator at Nucleus Network and progressing into project management roles. Clinical research proved to be a natural fit, allowing him to maintain strong connections to scientific inquiry while directly contributing to patient‑focused, real‑world outcomes.
He has since worked as a Clinical Project Manager across both CRO and site environments, developing deep expertise and a strong passion for clinical site operations. This commitment to improving patient care ultimately led Andrew to his current role as Site Director at Canopy Clinical Altona North, where he finds it deeply rewarding to positively impact patient outcomes across Melbourne’s western suburbs.

Paul has spent his entire medical career looking at healthcare from different angles. He is a GP by training, and spent 9 years focusing on GP work, specializing in mental health, before exploring other career paths within medicine. He worked in the education field as a GP registrar site supervisor, lecturer and tutor with Eastern Victorian General Practice Training, and a tutor at the Monash University medical school.
