Keri Anne Gladhill

Graduate Research Assistant

Cognitive and Behavioral Neuroscience

Keri is a fifth-year Ph.D. student at George Mason University in the Cognitive & Behavioral Neuroscience program. She graduated summa cum laude with a B.A. in Psychology in 2016 from Shippensburg University in Pennsylvania. She then went on to receive an M.S. in Experimental Psychology in 2018 from Saint Joseph’s University in Philadelphia while working in a Sensation and Perception lab. While at Saint Joseph’s University she completed her Master’s Thesis on Context Effects on Visual Working Memory. Her current research interests include different aspects of time perception and the effects of movement parameters on time perception using various neurological methods (fMRI, EEG, TMS). Keri has recently advanced to candidacy and plans to graduate Spring 2023.
