John completed his pulmonary and critical care fellowship at Indiana University after obtaining his medical degree from the University of Cincinnati and is currently a professor of medicine at Duke University Medical Center, and Medical Director of the Duke Lung Transplant Program in the Division of Pulmonary, Allergy & Critical Care Medicine. As Medical Director, his responsibilities include overseeing all phases of patient care from referral, determination of patient suitability of transplant candidacy, peri-operative care, and longitudinal post-surgical follow-up. Regarding direct patient care, he conducts several outpatient clinics per week and serves as an attending physician on the medical/surgical inpatient lung transplant teams. In addition to coordinating clinical care, as Medical Director he is involved in administrative oversight and participates in strategic transplant center-wide initiatives as well as quality control meetings to ensure that the Duke program is delivering the highest quality of care. Lastly, to help develop new frontiers and obtain advances for our patients to improve outcomes, he has been the site investigator for several trials that particularly deal with chronic lung allograft dysfunction.  

The Duke lung transplant program is an established premier academic transplant center and has one of the largest and most successful lung transplant programs in the country, having performed more than 2400 transplants since the program's inception in 1992. The program continues to grow with bilateral and single lung transplants as well as multi-organ transplants ranging from heart-lung, lung-liver, and lung-kidney transplants. The Duke lung transplant program has outcomes that are consistent with national averages in spite of a highly complicated patient mix, including the bridging to transplant of critically-ill patients off of ECMO, those with complex infectious disease issues, and patients over age 65. In addition to being at the cutting edge of clinical transplant medicine, Duke is one of the leading lung transplant research programs, with active clinical, translational and basic science research.
