Rajani Sebastian, PhD., is a researcher and a speech-language pathologist specializing in adult communication disorders and recovery after stroke. Dr. Sebastian is also involved in the noninvasive brain stimulation program at the Johns Hopkins Department of Physical Medicine and Rehabilitation.
Dr. Sebastian’s research focuses on recovery from poststroke aphasia with particular interest in brain plasticity. Her dissertation research examined language recovery in stroke using functional neuroimaging. And her post-doctoral fellowship focused on studying longitudinal language recovery in stroke using multimodality brain imaging techniques and using noninvasive brain stimulation to augment language recovery in stroke.
Dr. Sebastian has co-authored numerous publications on the topics of poststroke aphasia, brain imaging and language processing. She is a primary investigator for an ongoing NIH/NIDCD-funded study of the effects of transcranial direct current stimulation on poststroke aphasia.
