Dr. Lim’s research interest is in the use of neuroimaging approaches to identify circuit abnormalities in brain disorders such as schizophrenia, traumatic brain injury and addiction and then to use these circuits as treatment targets for noninvasive neuromodulation interventions. He is currently conducting studies that combine transcranial direct current stimulation neuromodulation with cognitive training to improve cognition in subjects with schizophrenia, traumatic brain injury, and addiction.
