Joanne Voisey is an Associate Professor within the School of Biomedical Sciences and the Centre for Genomics and Personalised Health at QUT. She is the course coordinator for the Master of Diagnostic Genomics at QUT.  For the last 15 years, she has been investigating risk factors and treatment response to mental illness. In recent years she has used epigenetics to gain a richer understanding of complex human disorders and the role of environmental risk factors such as stress and trauma. Of particular significance is her research with Vietnam veterans, uncovering epigenetic markers that are associated with PTSD, resilience and physical activity following combat exposure.  She has addressed challenging problems in schizophrenia research and her group were the first to identify epigenetic risk markers across the entire genome in brain samples.
