Travis SharkeyTravis Sharkey, MD, PhD
Medical Director – Ohio State Center for EMS
Assistant Medical Director – Worthington Fire Department

I started my educational pathway in computer science and engineering and electrical and computer engineering studying signal processing and artificial intelligence techniques. This led to a PhD in biomedical engineering while obtaining an MD through the Medical Scientist Training Program at The Ohio State University. I completed both an emergency medicine residency and EMS fellowship at The Ohio State University Wexner Medical Center before returning as faculty. As an EMS physician, I focuses on strengthening educational opportunities directed at real-world experiences of our local EMS providers. As a researcher, I'm investigating the use of artificial intelligence and natural language processing to support accurate and efficient dispatch of EMS providers to get the right resources to the right people at the right time.
