Eric Leuthardt

Eric C. Leuthardt (born 1973) is an American neurosurgeon, neuroscientist, inventor, and author. He is the Shi H. Huang Professor of Neurological Surgery at Washington University in St. Louis, where he serves as vice-chair of innovation in the Department of Neurosurgery, chief of the Division of Neurotechnology, and director of the Center for Innovation in Neuroscience and Technology.

He is recognized for pioneering human electrocorticographic (ECoG) brain-computer interfaces (BCI) and co-developing the IpsiHand system, one of the first FDA-cleared non-invasive BCIs for chronic stroke rehabilitation.

Early life and education Leuthardt was born in 1973 in Boston, Massachusetts, to a German father who worked in the auto industry and an Italian mother who was a teacher. He spent part of his early childhood in Stuttgart, Germany, before being raised primarily in Cincinnati, Ohio.

He received a B.S. in biology and theology from Saint Louis University and an M.D. from the University of Pennsylvania School of Medicine. He completed his neurosurgery residency at Washington University in St. Louis and Barnes-Jewish Hospital and earned an Executive M.B.A. from the Olin Business School at Washington University in St. Louis in 2024.

Career Leuthardt joined the Washington University in St. Louis faculty in 2006. He holds professorships in neurological surgery, neuroscience, biomedical engineering, and mechanical engineering & materials science. His clinical practice focuses on brain tumors, epilepsy surgery, laser interstitial thermal therapy, and Gamma Knife radiosurgery at Barnes-Jewish Hospital and St. Louis Children’s Hospital.

His laboratory develops neurotechnologies for motor restoration after stroke, speech decoding, and advanced brain mapping. He co-developed the IpsiHand system through Neurolutions, which received FDA De Novo authorization in 2021 for chronic stroke rehabilitation.

A 2025 peer-reviewed study and preliminary results from a 2026 randomized controlled trial (presented at the International Stroke Conference) demonstrated functional improvements in patients using the device; full peer-reviewed publication of the latest trial is anticipated.

Leuthardt is a inventor with over 600 U.S. patents granted and more than 1,000 pending on neurotechnology devices and medical instruments.

He serves as CEO of Aurenar, developing a single-use, wearable transcutaneous auricular vagus nerve stimulation device for ICU patients to modulate inflammation non-invasively and potentially reduce life-threatening complications. Fellow, American Institute for Medical and Biological Engineering (2025)
