Physician, Assistant Professor
Pulmonary Disease, Critical Care Medicine
Department: Internal Medicine
As a pulmonary and critical care specialist at The Ohio State University Wexner Medical Center, I provide comprehensive and compassionate care to patients with both acute and chronic conditions. I regularly treat interstitial lung disease (ILD) and other pulmonary issues including sarcoidosis, bronchiectasis, chronic obstructive pulmonary disease (COPD), asthma and others.
I work hard to understand both the medical and personal aspects of my patients’ conditions and how their symptoms impact their daily lives. I offer customized treatments that best meet the unique needs and values of each of my patients. I also consider the entire family’s needs. I was a high school teacher in New York City before I enrolled in medical school and that experience instilled in me the importance of communities and families in providing patient care.
In addition to patient care, I am also focused on innovative research to advance the treatments we can provide. My current research examines access to care for patients with interstitial lung disease. I have published peer-reviewed journal articles pertaining to pulmonary fibrosis and other chronic pulmonary conditions.
When I am not working, I enjoy spending time with my wife and son outdoors. Our family enjoys hiking and going to parks and playgrounds around Columbus.
Please note: Not all physicians schedule patients at each listed location.
I am a clinical assistant professor in the Department of Internal Medicine’s Division of Pulmonary, Critical Care and Sleep Medicine at The Ohio State University. In addition to treating patients with interstitial lung disease and critical illness, I am focused on advancing health equity in the care of chronic lung disease through research. My current work examines access to care for patients with interstitial lung disease and sarcoidosis and I have published multiple peer-reviewed journal articles pertaining to pulmonary fibrosis and other chronic pulmonary conditions.
Prior to joining faculty at Ohio State, I received a master’s degree in teaching science from New York University as well as a master’s degree in clinical research from the University of Virginia. I earned my MD from the SUNY Downstate Health Sciences University College of Medicine in Brooklyn, N.Y., and completed a pulmonary and critical care fellowship at the University of Colorado.

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.
