Office of the Dean of Research
Ayanna K. Thomas
Dean of Research for Arts and Sciences
Professor of Psychology
Ayanna K. Thomas was named Dean of Research for the School of Arts and Sciences in 2021. Dean Thomas began her career at Tufts in 2007, when she joined the Department of Psychology as an Assistant Professor and established the Cognitive Aging and Memory Lab. She was promoted to the role of Associate Professor in 2013 and Professor in 2019. From 2016 to 2021 she served as Director of Graduate Studies for her department.
Dean Thomas received her PhD in Cognitive Psychology from the University of Washington, and then spent three years as an NIA postdoctoral fellow at Washington University in St. Louis, MO. Her research focuses on the relationship between memory and metamemory. She examines the role metamemory plays in memory acquisition, distortion, and access using a balanced approach towards basic and applied designs as they relate to education, eyewitness memory, and age-related changes in memory. Her more recent work has demonstrated that memory errors can be exacerbated when people are not able to exercise metacognitive control at retrieval.
