The growing number of refugees and asylum seekers are one of the most significant global challenges of this generation. We are currently witnessing the highest level of displacement in history, with over 65 million displaced people in the world. Refugees and asylum seekers are at higher risk to develop mental illness due to their trauma and chronic stress exposures, and particularly post-migration stressors. Yet global and Australian psychiatric research in this area is greatly lacking, particularly with respect to our understanding of the molecular underpinnings of risk and resilience to mental illness in traumatised populations. In this Viewpoint, we explore the reasons behind the lack of refugee mental health research and use this context to propose new ways forward. We believe that scientific discovery performed with a multidisciplinary approach will provide the broad evidence-base required to improve refugee mental health. This will also allow us to work towards the removal of damaging policies that prolong and potentiate mental health deterioration among refugees and asylum seekers, which impacts not only on the individuals but also host countries’ social, economic and healthcare systems.
