Adrian Walker

Research Officer

Adrian is a research officer studying how we can improve health outcomes for those with mental illness, as well as those with intellectual disability, using large-linked datasets. Adrian completed his Bachelors in Psychological Science (Hons, Class I) in 2015, his PhD in Cognitive Science in 2019 (both from UNSW Sydney). Adrian has also worked coordinating the UNSW School of Psychology Peer Mentoring Programs, and as a data analyst in Psychology. Adrian is passionate about improving the experience of people with disability in the healthcare sector, and equipping medical professionals with the tools to make better decisions regarding disability.
