Housing state of the art imaging, cytometry and animal facilities, you will hone new skills and learn the latest techniques from internationally renowned researchers whilst building the foundations for a future that could see you make breakthroughs that save lives. “You go into the lab not knowing what’s going to work. Nine times out of 10 it doesn’t work, but then the one time it does, it really hits you and it’s what keeps you hooked. But even when it’s wrong, that helps steer you in the right direction.” Stuart Cook Former Honours Student Research Assistant, Melanoma Oncology & Immunology Program Stuart started at Centenary at the beginning of 2017 as an Honours Student, and is now a Research Assistant in Professor Peter Hersey’s Melanoma Oncology & Immunology Program. centenary.org.au/students
