Neuromodulation Lab


Welcome to the Neuromodulation Lab, where we conduct rigorous research into human behavior and cognition, focusing on core physiological parameters such as cortical excitability, neuroplasticity, and brain oscillations. We use state-of-the-art methodologies including noninvasive brain stimulation, neuroimaging techniques, and behavioral paradigms.

Along with the basic research,we are dedicated to translating our findings into practical applications for individuals grappling with cognitive and emotional impairments(applied cognitive neuroscience). With a multidisciplinary approach, our team and collaborators comprise esteemed professionals in cognitive and behavioral neuroscience, biomedical and electrical engineering, psychiatry, neurology, and psychology. We encourage and support diversity in our lab.


We have two primary goals:
1- Studying the core physiological components of human behavior and cognition in healthy and clinical populations (cognitive neuroscience)
2- Modifying core physiological components of human behavior and cognition in neuropsychiatric and neurological disorders (applied cognitive neuroscience)

Research projects

Active projects:
1- Modulating behavior, cognition, brain excitability, and neuroplasticity with non-invasive brain stimulation in healthy populations, neuropsychiatric disorders (e.g., schizophrenia, OCD, affective disorders), neurodevelopmental disorders (e.g.,ADHD, autism) and neurological disorders (e.g., Alzheimer’s disease, Parkinson’s disease, Stroke)(recruiting research assistant).
2- Entrainment of brain oscillations in healthy elderly and Alzheimer's disease
3- Role of Sleep and circadian rhythms in brain plasticity and cortical excitability

Projects to begin in the early future:
1- Animal studies of neuromodulation (recruiting research assistant)
