About Me

As a neurologist, I focus on advanced therapeutic options for Parkinson’s disease, dystonia and tremor disorders. In particular, I use deep brain stimulation (DBS), intestinal and subcutaneous infusions, and other advanced therapeutic procedures. I also specialize in the treatment of dystonia, blepharospasm and other movement disorders with botulin toxin under electromyographic guidance.

I strongly believe in developing a therapeutic alliance with each patient to help them find appropriate treatment.

What I like most about Ohio State is the spirit of interdisciplinary collaboration between neurologists, neurosurgeons and basic science researchers. It’s a perfect match to advance the clinical and research standards of neuroscience into the era of human-technology interface.

In my spare time, I enjoy working out and traveling.
