Keri Anne Gladhill

Graduate Research Assistant

Keri earned her Ph.D. at George Mason University in the Cognitive & Behavioral Neuroscience program this year (2023). 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 secured a post doctoral position at Florida State University working with Dr. Derek Nee investigating cognitive control.

Center for Adaptive Systems of Brain-Body Interactions (CASSBI)
PI: Siddhartha Sikdar

    • Interdisciplinary program in disability-related research
    • Participating in community-engaged STEM graduate training
    • Collaborating through a multidisciplinary team to better understand Parkinson’s disease and care team communication
    • Communicating with community stakeholders including neurologists, patients, and caregivers

Research Assistant: Investigations of Movement Parameters on Timing and Perception

Spatial Temporal Action Representation (STAR) lab – George Mason University
PI: Martin Wiener, PhD
Sensorimotor Integration lab – University of California, Davis
PI: Wilsaan Joiner, PhD

    • Collaborating across labs to investigate effects of movement on time perception
    • Conducting experiments using a robotic manipulandum (UCD) and a modified non-robotic manipulandum (GMU)
    • Including neurological measures such as TMS (transcranial magnetic stimulation) and EEG (electroencephalogram)
