Rajani Sebastian
Post-Doctorate Research Fellow

Rajani is a Speech Language Pathologist who studies recovery from aphasia with particular interest in brain plasticity.  She received her bachelor's degree in Speech and Hearing Science and master's degree in Speech Language Pathology from the University of Mysore, India. Her doctoral training took place at the University of Texas at Austin under the guidance of Dr. Swathi Kiran. Her Ph.D. work focused on examining the neural correlates of lexical-semantic processing in chronic stroke patients with aphasia using fMRI. She completed her clinical fellowship in Speech Language Pathology before joining Johns Hopkins University in the lab of Dr. Argye Hillis as a postdoctoral fellow in 2012.  

The primary focus of her postdoctoral fellowship is to investigate the effects of cerebellar transcranial direct current stimulation on language therapy in patients with chronic aphasia and to study neural plasticity related changes associated with aphasia therapy.
She is also involved in investigating the longitudinal neural changes associated with language recovery after a stroke using multimodal imaging techniques.
