About Me

I am a physiatrist, or a specialist trained in physical medicine and rehabilitation, with subspecialty in neuromuscular medicine. I work with patients who are dealing with disorders that affect their muscles, peripheral nerves, motor neurons or neuromuscular junctions.

As a clinician, I help my patients by providing them with a precise diagnosis, followed by cutting-edge treatments. In addition, I give my patients access to clinical trials for new and innovative therapies. As a scientist, I am interested in understanding and reducing the effects of genetic neuromuscular disorders and aging on the neuromuscular system.

I feel that my dual training in physical medicine and rehabilitation and neuromuscular medicine gives me a unique perspective to help treat my patients. It helps me understand the impact on the body and design the best treatment plan. My primary goal is to reduce the burden that diseases have on patients and maximize the function of the neuromuscular system.

I truly enjoy Ohio State’s collaborative environment. There’s a strong sense of teamwork among the clinicians and scientists on our neuromuscular team. This allows scientific discoveries to effectively translate to clinical treatments.

In my free time, I enjoy training for ultramarathons, triathlons and other endurance sports. I am currently training for the Burning River 100 mile run.
