Physician, Assistant Professor
Neurology
Department: Neurology
I am a neurologist physician-scientist who specializes in caring for patients with multiple sclerosis (MS) and autoimmune disorders of the central nervous system. I am passionate about finding better treatments for MS that will prevent disability and disease progression. I believe in providing a patient-tailored approach to help select the best treatment for that individual and help promote the best quality of life while living with MS.
My laboratory research is focused on oligodendrocytes, the myelin making cells of the central nervous system, and how they function in the context of inflammation and aging. Long-term goals of my research program are to find strategies to promote remyelination and repair and prevent neurodegeneration in relapsing and progressive MS.
I enjoy mentoring and teaching medical students, residents and fellows and have a particular interest in teaching around LGBTQ health. In my free time I enjoy being outdoors and spending time with my family and pets.

I am a physician-scientist specializing in multiple sclerosis (MS) and other autoimmune disorders of the central nervous system. My goal in caring for people living with MS and other central nervous system inflammatory disorders is to find the best treatment regimens that will prevent relapses, new lesions and reduce progression. Symptom management is also an important aspect of therapy, and finding medications and other approaches to maintain quality of life is an important part of treatment.
One of my goals is to be a physician who people feel comfortable talking to about any concerns or with questions about their neurological disorder.
Neuroimmunologists/MS specialists may be the physicians people with these disorders see regularly throughout their lives, and my goal is to be the stability in their MS care. It is also my priority to connect people to the multidisciplinary specialists in our Multiple Sclerosis and Neuroimmunology Center, and make sure people are well-supported and are empowered to explore the resources that are available.
My research aims to understand how glial cells in the central nervous system, called oligodendroglia, are influenced by an inflammatory environment. Oligodendroglia are responsible for myelinating the central nervous system, and in multiple sclerosis, damage to myelin and the oligodendroglia results in demyelinated lesions and neurological disability. No therapies are currently approved for promoting remyelination and repair and restoring neurological disability in multiple sclerosis.
The goal of our research program is to identify targetable pathways in oligodendroglia that can promote their normal function to repair and remyelinate lesions. Oligodendroglia assume alternative cell fates in response to inflammation, and how this influences their properties and repair capacity is unknown. Understanding of how oligodendroglia are altered by an inflammatory environment, we believe, will lead to the development of therapies to promote myelin repair and restore neurological function in people living with multiple sclerosis.
I am passionate about discovering therapies to help restore neurological function in MS and to prevent or improve neurological disability. My laboratory is focused on oligodendroglia, with the goal of developing therapies that can promote remyelination and repair. Mentoring and teaching the next generation of neurologists, MS specialists and researchers is important to me. I serve as the Ohio State University College of Medicine site director for two trainee development summer programs through the National Multiple Sclerosis Society – the medical student summer MS clinical program and the undergraduate summer MS research program. I also serve as a clinical preceptor for the Ohio State College of Medicine and its Medical Scientist Training Program, where medical students who are interested in neurology work with me in MS clinic.

At The Ohio State University Wexner Medical Center, we support a faculty member’s research and consulting in collaboration with medical device, research and/or drug companies because a faculty member’s expertise can guide important advancements in the practice of medicine and improve patient care. In order to provide effective management of these relationships, the University requires annual disclosures from all faculty members with external interests related to their University responsibilities.
