Mark is a training psychiatrist from Australia who is completing a PhD, at King’s College London, regarding the link between stress and depression. He would like to understand the biological mechanisms underlying this connection and this currently involves torturing human neural stem cells in a dish with stress hormones and inflammatory molecules, and investigating the extent to which antidepressants and fish oils can reverse these effects. He hopes to contribute to reducing the burden of depression through clinical practice, research and public engagement. He recently won the national competition ‘I’m a neuroscientist get me out here’ which impressed his mum.
