Assistant Professor, Psychology
Research and Teaching Interests
My research focuses on understanding how the brain allows us to adapt the way we make decisions. We explore how different types of information are represented in the brain and integrated to drive behavior, employing mathematical models of cognition and functional MRI to map cognitive processes onto neural systems. This work covers both healthy adult populations and clinical populations with elevated anxiety and depression. Current projects include investigating individual differences in the ability to exert executive control over cognitive processes, and exploring how emotions affect memory and decision making.
