Aryn Gittis, Ph.D.
SAB Co-Chair
Carnegie Mellon University
Pittsburgh, PA

Read Bio

Dr. Aryn Gittis studies the organization and function of neural circuits in the basal ganglia in order to understand the role that region of the brain plays in learning, movement, and neurological diseases such as Parkinson’s Disease and dystonia. Her lab uses a variety of techniques including electrophysiology, optogenetics, histology and behavior to understand how circuits in the basal ganglia affect motor control.

Gittis is the recipient of a NARSAD Young Investigator Grant from the Brain & Behavior Research Foundation to study the neuronal mechanisms that underlie compulsive behavior. She was a finalist for The Eppendorf & Science Prize for Neurobiology, an international prize that encourages the work of promising young neurobiologists.

Marc F. Schmidt, Ph.D.
University of Pennsylvania
Philadelphia, PA

Read Bio

Dr. Marc Schmidt is currently Professor of Biology at the University of Pennsylvania where he studies the neural circuits involved in acoustic communication using songbirds as a model system. His work has focused on the motor control of song production and the role of behavioral state on sensory processing. Because the specialized circuits involved in vocal communication rely on the same basal ganglia circuitry that is affected in TS, this work allows the study of sensorimotor integration and processing within a natural behavior. Dr. Schmidt is also director of the Biological Basis of Behavior program at the University of Pennsylvania.

Having an adult daughter with TS, Dr. Schmidt has been heavily involved in TS outreach. He founded Waffles for Tourette, which raises awareness of TS at local Farmers Markets, and runs a workshop twice a year in collaboration with the Integrative Health Program at the Children’s Hospital of Philadelphia. This workshop was funded by a TAA/CDC seed grant and consists of a one-day workshop for parents and teens blending education and advocacy with mindfulness and theater improvisation techniques to address TS.

Kristina Simonyan, M.D., Ph.D.
TiHo University of Hannover, Germany

Read Bio

Kristina Simonyan received her medical degrees (M.D. and Dr. med.) from Yerevan State Medical University in Armenia and Georg-August University in Goettingen, Germany, as well as a PhD degree in Neurobiology from TiHo University of Hannover, Germany. She completed her medical residency in otolaryngology and clinical research fellowship in movement disorders, neurolaryngology and neuroimaging. Dr. Simonyan studies the neural mechanisms of normal and diseased speech production and other complex voluntary motor behaviors. Her clinical research program is focused on focal dystonia, a debilitating neurological movement disorder causing involuntary muscle spasms in different body regions. Her methodological approach bridges brain imaging, computational neuroscience, genetics and clinical trials for identification of objective diagnosis, prediction of risk, and treatment of dystonia. Her recent studies have mapped the large-scale neural architecture underlying speech production and its impairments in focal dystonias. This work has led to identification of potential neural markers of laryngeal dystonia (or spasmodic dysphonia) as well as the assessment of new therapeutic options for the treatment of this disorder. Her research is currently supported by the National Institutes of Health (NIDCD and NINDS), Jazz Pharmaceuticals, and Amazon Web Services.
