Research Interests: 

  • Novel diagnostics and therapeutics to improve lung transplantation outcomes
  • Lung virome and microbiome in health and disease
  • Total Transplant Care Protocol: Lung Transplant Biorepository

Current Research: My research focuses on improving outcomes after lung transplantation by studying novel diagnostic and therapeutic approaches to allograft rejection. I currently lead the Lung Transplant Research Group and am PI for several clinical trials. I oversee collection of data and specimens for the lung transplant biorepository and have an interest in utilizing this unique resource to evaluate the lung virome and microbiome.

Active projects include:

  1. Letermovir for CMV prophylaxis in lung transplant recipients intolerant of valganciclovir
  2. Early acute kidney injury after lung transplant
  3. Use of cell-free DNA to detect allograft dysfunction
  4. Extracorporeal photopheresis for the treatment of bronchiolitis obliterans syndrome
  5. Inhaled cyclosporine for early bronchiolitis obliterans syndrome
