Visual Perception and Plasticity Lab

The Visual Perception and Plasticity (VPP) Lab studies neuroplasticity in healthy and clinical populations across the lifespan. We use a combination of psychophysics, eye tracking, 3T fMRI and 7T layer fMRI, brain stimulation (tDCS, tRNS, and/or TMS), computational modeling, online crowdsourcing “big-data”, developmental and neuropsychological approaches in our research.  The lab's current focus is to integrate visual behavior, neuroimaging, and neurorehabilitation to achieve precision vision recovery in patients with lesions in the visual cortex.

Who we are

We are a Translational Cognitive Neuroscience Lab in the Department of Neurology and Center for Brain Plasticity and Recovery at Georgetown University Medical Center led by Dr. Tina Liu. Our research group shares a common passion to understand the core principles of neuroplasticity in humans. Our long-term goal is to leverage this knowledge to develop precision vision rehabilitation strategies for patients with brain lesions, such as stroke, epilepsy surgery, traumatic brain injury, and brain tumors.  

Latest lab news

The Visual Perception and Plasticity (VPP) Lab is recruiting Graduate Students through the Georgetown Interdisciplinary Program in Neuroscience (IPN), a Postdoctoral Researcher, and multiple Undergraduate Research Interns to study visual plasticity in stroke patients for precision recovery.
