About Me

As a pulmonologist and a critical care intensivist, I specialize in treating patients with advanced lung disease prior to and following their lung transplantation. I also enjoy caring for critically ill patients in the ICU.

In lung transplantation, we see patients with a variety of advanced lung diseases, each with unique challenges that require individualized treatments. Living with an advanced lung disease and going through the process of a lung transplant are not only physically demanding, but emotionally draining as well. Personally, I believe that successful treatment means a comprehensive approach, including state-of-the-art medical and surgical therapies, a collaborative team of experts and a personal touch to reassure each patient that we’ll do our very best to improve his or her health and well-being.

I truly enjoy working here at Ohio State. The people here are honest, open and very caring. We have a very family focused atmosphere, especially in regard to our lung transplant team.

When I’m not working, I like to spend time traveling and relaxing with my family. I also enjoy playing basketball, at least for as long as my body holds up!


  • My primary research interest is the study of the lung microbiome, and specifically, the virome in lung transplantation and other pulmonary disorders

I don't think he heard what I was saying about my knees & walking, they are bone to bone. Some days are better than others. But I believe he was just concentrating on my lungs instead of the whole body.
