Dr Susannah Tye
School of Psychology
Role and profile
Dr. Tye serves as the Unit Chair of Health Behaviour and is an active researcher in the School of Psychology. She investigates the neurobiological mechanisms mediating stress, depression and addiction, as well as the modulatory role of novel treatment strategies such as deep brain stimulation. An advocate for enhancement of youth health awareness and neuroscience-based education practices, Dr. Tye is also actively involved in determining gaps in youth health and mental health knowledge and rectifying these issues through development of educational resources and programs that promote health behaviours and a passion for lifelong learning.
HBS110 Health Behaviour
Dr. Tyes mental health neurobiology research program aims to determine the biological mechanisms by which stress hormones disrupt, and effective pharmacotherapies and neuromodulation technologies restore, neurotransmission in mental illness, particularly depression. To achieve this, Dr Tye utilises electrochemical recording techniques relatively novel to Australian neuroscience to monitor rapid synaptic neurotransmission in animal models of neuropsychiatric illness through assessment of:
Neurotransmitter flow through neuronal pathways;
Neurotransmitter dynamics (release and reuptake) at the synapse;
Stress hormone modulation of synaptic plasticity;
Dr Tye is also keenly interested in translating recent medical and neuroscience research findings into relevant and engaging educational resources that serve as effective tools in improving health-related behavioural choices through enhanced learning opportunities. To achieve this, a complementary component of her research assesses the relative level of health and mental health awareness among Australian youth and the impact of educational programs on their current lifestyle choices.
Dr Tye works closely with world leaders in these fields through collaborative partnerships with the Mayo Clinic, University of Memphis, University of Illinois, Emory University, UNESCO and Macquarie University.
