Dr Simmons primary career objective is to improve wellbeing and mental health outcomes for children and adolescents exposed to adversity, and particularly stressors that occur in the family context. His research extends across the lifespan in meeting this objective, but with a particular focus on the first two decades of life in examining how environmental factors (such as stress, parenting, poverty, etc.) and biology interact in increasing risk for (and protection against) poor mental health outcomes. Current studies examine the development and function of the brain, and endocrine and immune systems in these processes. Dr Simmons is also conducting several large-scale studies examining the role of the human microbiome in mental health and behaviour, including one with the Melbourne Museum (see below for further information).
Dr Simmons completed his PhD at The University of Melbourne in 2011, and currently holds a joint position at the University of Melbourne across the Melbourne Medical School (Psychiatry – Melbourne Neuropsychiatry Centre) and the Melbourne School of Psychological Sciences. He also holds an honorary appointment at the Centre for Adolescent Health at the Murdoch Children’s Research Institute.
