For most of us, reaching for an object, such as an apple or a pen, is something done seamlessly without requiring much thought. However, carrying out a voluntary movement requires a stream of intricate computations in the brain for planning, initiating, and executing even a simple action. Many neurological and psychiatric disorders – and also healthy ageing – can all influence these computations. My research interests lie in understanding these changes that occur across the lifespan and in cases of disease. I use behavioural tasks that tap into principles from computational neuroscience: for example the integration of different sources of information for performing an action. I combine these tasks with brain imaging methods, such as functional magnetic resonance imaging, which allows me to examine the activity and connectivity of brain networks. My ongoing research following my PhD at Cambridge looks at the effect of age on the brain's motor system. Ageing is typically associated with increased variability in performance across individuals. My research endeavour, therefore, is to find the markers that not only predict healthy ageing, but also those that identify the brain changes that put people at risk to their well-being. Alongside research, I work in clinical psychiatry at Cambridge and Peterborough NHS Foundation Trust.
