Biography Joined UT Southwestern: 2021 Clinical Interests: Vikram Shakkottai, M.D., Ph.D., sees patients with Cerebellar Ataxia, Inherited & Sporadic Disorders of Cerebellar Dysfunction, Balance Disorders, and Other Movement Disorders. Trainee Education: Dr. Shakkottai co-leads the Resident Research Track, for those residents who aspire to lead an independent career as a wet-bench or dry-bench researcher. Research: The long-term goal of Dr. Shakkottai’s clinical and laboratory research is to determine whether alterations in neuronal physiology contribute to motor dysfunction and degeneration in cerebellar ataxia. Work in Dr. Shakkottai’s laboratory has identified dysfunction in the cerebellum common to many murine models of ataxia, with the identification of ion channels regulating Purkinje neuron intrinsic excitability as key targets for a shared therapeutic strategy. Background: Dr. Shakkottai obtained his medical degree at the Christian Medical College, Vellore, India, and his PhD at the University of California, Irvine. He received his Neurology Residency training at Washington University/Barnes-Jewish Hospital and was a fellow in Movement Disorders at the University of Michigan. He joined the full-time faculty at the University of Michigan in 2010.
