She uses a combination of behavioral and event-related brain potential (ERPs) methodologies to understand how experience modifies the neural bases of cognitive control.

Dr. Tiernan is thrilled to share her talents in Cognitive Neuroscience with the Bridge program. It's her first full summer in Sewanee and she's most definitely looking forward to working with new students and conducting new and exciting research.
