Dr. Konczak is a full professor in the School of Kinesiology at the University of Minnesota. He is the head of the Human Sensorimotor Control Laboratory and also serves as director of a university-wide Center for Clinical Movement Science. Since 2011, Dr. Konczak’s group conducts research on somatosensory function in people with laryngeal dystonia. He is the principal investigator of several clinical trials that investigated whether vibro-tactile stimulation of the larynx can help to alleviate the voice symptoms of laryngeal dystonia. His research has been funded by the U.S. National Institutes of Health, the U.S. National Science Foundation, the German Science Foundation and the European Commission.


Dr. Klein is the Director of the Emory Voice Center, Chief of Division of Laryngology, Vice-Chair of Faculty Development and Willard and Lillian Hackerman Professor in Voice in the Department of Otolaryngology at the Emory University School of Medicine. Dr. Klein’s clinical specialties include the treatment of laryngeal disorders and the professional voice. He has almost 20 years experience treating patients with laryngeal dystonia. He has published several articles on the condition and participated in dystonia research funded by the NSDA and Cure Dystonia Now.


Dr. Bhaskaran is an assistant professor at the Department of Biology of Hamline University in St. Paul, Minnesota. She is a biomedical engineer by training and holds a PhD in rehabilitation sciences. As a postdoctoral researcher she was instrumental in conducting the clinical trials that examined vibro-tactile stimulation as a potential treatment for people with laryngeal dystonia.  


Dr. Watson is associate professor at the Department of Speech, Language and Hearing Sciences at the University of Minnesota. Dr. Watson has been involved in the study of voice for over 35 years, first as a musician, then as a clinician and scientist. For the past 15 years his research utilized acoustic methods to determine the type and severity of voice disorders and how they are related to behavioral and neurogenic origins. 


Arash is a Senior Research Scientist at Meta, located in Redmond, WA. In his current position, he specializes as a User Health & Safety Researcher, driving innovations in Augmented Reality (AR), Virtual Reality (VR), Mixed Reality (MR), and Wearables across various devices, platforms, and applications.

Before joining Meta, Arash spent 5 years as a Graduate Research Fellow at the Human Sensorimotor Control (HSC) Lab at the University of Minnesota. During this time, he worked alongside a diverse team of experts in neuroscience, physical therapy, kinesiology, speech therapy, and biomedical engineering. His research focused on human neuromotor control, learning, neurorehabilitation, and the design of medical devices.

One notable aspect of Arash’s doctoral research project was his exploration of vibro-tactile stimulation as an alternative treatment for laryngeal dysphonia.

His extensive research experience in the areas of human sensorimotor control, perception, and cognition has provided him with valuable insights and expertise, enabling him to drive innovation and enhance user experiences.
