During this time, Dr Petrie has worked on a range of projects at a coronial, epidemiological and clinical level, including projects prioritising lived experience.

Dr Petrie has extensive experience in the application of both quantitative and qualitative methods to suicide prevention, workplace mental health, and intervention development and evaluation. Her primary research interest is in understanding and addressing the risk and protective factors for mental ill-health and suicidality, particularly in high-risk workforces and vulnerable populations, and the translation of this evidence into practice. A particular interest and area of expertise is exploring and addressing mental illness and suicidality among frontline workforces, particularly healthcare professionals. My career objective centres around knowledge generation and translation into policy and practice to prevent mental disorder and suicidality among the general population as well as the working population, in particular at-risk occupations and vulnerable groups.
