Research summary | Mental health and its relationship to how we perceive our body |
Research
My research focuses on mental health and its relationship to interoception (how we perceive our body).
I use neuroimaging and computational models to better understand how the brain perceives and learns about changes in the body, with a particular focus on breathing. My work also aims to understand how currently available treatments such as anxiolytics and exercise can improve conditions such as anxiety and depression.
