Areas of expertise Stress has been called the "common cold of the psyche". When excessive or overwhelming it can cause both physical and psychiatric morbidity. The aim of my groups work is to better understand the neurobiological underpinnings of anxiety disorders and stress related medical conditions using a variety of approaches, but with a focus on serotonin. Techniques used include CO2 inhalation and other challenge studies, rapid tryptophan depletion and assessment of tryptophan turnover in different conditions. Measures include behavioural, neuroendocrine and cardiovascular. Conditions include volunteer, panic disorder, social phobia, general anxiety disorder, major depression and irritable bowel syndrome.
