- My research focuses on the cognitive and neural mechanisms underlying speech comprehension. I am particularly interested in how listeners use contextual information to understand a speaker's intended meaning, given that many of the words we use have multiple meanings (e.g. "ace" can refer to a tennis serve or to a playing card and is also a synonym for "brilliant"). Working with Matt Davis, I am using EEG, MEG and behavioural methods to test cognitive theories and learn more about the brain networks that support successful language comprehension.
