Bridianne O'Dea

Senior Research Fellow

Dr Bridianne O’Dea is a Senior Research Fellow at the Black Dog Institute. She completed her PhD in Health Sciences at the University of Sydney in 2013 after completing an honours degree in e-mental health. Her PhD examined the relationship between social networking sites and emotional wellbeing in early adolescents. Her current research areas include adolescent depression and anxiety, e-health interventions for mental health, and harnessing social media for suicide prevention.  O’Dea has extensive expertise in e-health project management, social media, online service delivery and recently developed expertise in machine learning. Dr O’Dea is interested in improving access to evidence-based care through technology supported through her involvement with the Digital Dog research program. Dr O’Dea has been involved in the development of multiple e-mental health apps and was also responsible for co-leading the investigations into social media and suicide, including the Twitter studies and the Ground Truth Project, and contributing to the collaborations with CSIRO, Amazon Web Services, and PRADA at Deakin University, established by Prof. Christensen. She currently holds an Early Career Fellowship from the Society for Mental Health Research. Dr O’Dea is leading the development of a web-based stepped care mental health service for adolescents and mobile apps for depression prevention.
