Dr MacDonald’s research focuses on the behavioural, neurophysiological and genetic mechanisms of impulse control i.e. how we control our actions. She is especially interested in how these mechanisms may be influenced by dopamine dysregulation as seen in Parkinson’s disease and other dopamine-related disorders. She utilizes techniques such as non-invasive brain stimulation, genotyping, computational modelling and electroencephalography to investigate mechanisms of inhibitory control.
You can read a bit more about her current research focus in this article.
