My Biography & Research


As a lung doctor (pulmonologist), I treat children and adolescents who have cystic fibrosis and chest wall disorders. I’m also a sleep medicine specialist, and I treat patients who have many types of sleep disorders.

I was drawn to my area of medicine by the great mentors I had in pediatric pulmonology, both in medical school and residency. Pediatric pulmonology provides the opportunity to do research, procedures, inpatient care and outpatient care. In addition, working with children and families is amazing and very rewarding.

My training in pediatric pulmonology and sleep medicine allows me to provide care for a wide range of childhood breathing concerns. We have clinics available at multiple Cincinnati Children's outpatient campuses, and we also serve patients via telemedicine. I enjoy doing telemedicine visits, since it allows me to learn new technology while providing convenience for families.

I provide family-centered and personalized care options to help children with medical concerns. Each child is unique, and families deserve choices. They are true partners in their child's care.

In 2016, I was honored to win the HOPE Award for Provider of Excellence from Department of Orthopaedics for my work in the Chest Wall Disorders Clinic. From 2014 to 2016, I was named one of Cincinnati Magazine's Top Doctors.

I direct cystic fibrosis clinical trials, with a focus on therapeutic trials of CFTR modulators that improve function of the cystic fibrosis protein in patients. Mutations in the CFTR gene inhibit it from performing its function, and can result in cystic fibrosis.

In my free time, my six children keep me busy.
