 I've worked in lots of different areas of the nervous system, but in 2000 I had the opportunity to go to America and work on a project looking at the genetics of anxiety in mice and mouse behaviour. Ever since then I've just really been interested in how the brain works, how the brain responds to stress and in particular in depression and anxiety. So a long time ago I wanted to be a medical doctor and then actually I realised that that was perhaps a bit too close. So I wanted to do good in the clinic but without actually being in front of patients and so I decided to go down the science route and biology route and ended up in this field of using radioactivity for imaging and treating disease. Because it's something that is super exciting, it's at the forefront of science, it's complicated and requires a big team of people but it is also something that I know that if I do something well and if I create a new imaging tool or therapy then in the next few years I can see it being used in patients.
