Research Summary
My research investigates neural mechanisms underlying symptoms of severe mental illness and addiction using a range of assessments and neuroimaging procedures. In recent years, the focus of my work has been towards studying the symptoms of psychosis and addiction using resting-state connectivity and novel paradigms to assess stress reactivity and social decision-making. Accumulating findings from my previous studies have highlighted a role of the insular cortex in both symptom dimensions. To further investigate this link, I am developing novel paradigms to study a basic process associated with the insula, termed interoception, which is one’s awareness of the physiological state of the body. This domain of work integrates sensory and affective processes with self-monitoring, and by doing so may provide a novel lens for studying psychosis and addiction. Future work also plans to expand my studies of stress reactivity and social decision-making by examining additional factors such as trauma exposure, as well as clarifying the roles of interoception and emotion regulation in distress intolerance and mistrust behaviors.
