The Pulmonary & Intensive Care Translational Outcomes Research (PICTOR) Group

The Pulmonary & Intensive Care Translational Outcomes Research (PICTOR) Group is a clinical and translational research group led by David J Lederer, MD, MS and Matthew R Baldwin, MD, MS. Our mission is to identify novel risk factors for interstitial lung disease and to improve the lives of lung transplant recipients, adults with advanced lung diseases, and survivors of critical illness. We also seek to train the next generation of clinical and translational investigators in pulmonary and critical care medicine. 

The Group has 7 Cores:

  • Pulmonary Core, directed by David J Lederer, MD, MS
  • Critical Care Core, directed by Matthew R Baldwin, MD, MS
  • Autoimmune Lung Disease Core, directed by Elana Bernstein, MD MS
  • Research Coordination and Regulatory Core, directed by Tatiana Blue
  • Training & Career Development Core, directed by David J Lederer, MD, MS 

We have made novel discoveries about subspecialty care and its role in improving the outcomes of adults living with idiopathic pulmonary fibrosis, disparities in access to subspecialty pulmonary care and lung transplantation, and the impact that body composition and frailty have on older survivors of critical illness and on lung transplantation outcomes.

For more information, please contact Dr. Lederer [] or Dr. Baldwin [].

Clinical and Research Infrastructure Integration

is integrated into active clinical programs at Columbia University Medical Center, including the New York Presbyterian/Pulmonary Fibrosis Foundation Interstitial Lung Disease Care Center, the NYP Lung Transplant Program, the Medical Intensive Care Unit at Columbia University, and the NYP Scleroderma Program (directed by Elana Bernstein, MD, MS).

works closely with existing research infrastructure and services at, including the CTSA-funded Irving Institute for Clinical and Translational Research, the Mailman School of Public Health’s Patient-Oriented Research Master’s degree program, the Office of Clinical Trials, and the Institutional Review Board.

What We Do

The PICTOR group conducts clinical and translational research in the following areas:

  1. Using population-based studies, such as the Multi-Ethnic Study of Atherosclerosis (MESA), we are examining the causes of lung injury, inflammation, and fibrosis in humans.
  2. We are examining the roles of obesity, body composition, and frailty in early lung transplant outcomes.
  3. We are performing early work examining obstructive sleep apnea and its contribution to subclinical alveolar epithelial cell injury and consequent fibrosis.
  4. We are examining disparities in access to subspecialty pulmonary care and lung transplantation in the United States.
  5. We are examining the unmet palliative care needs of ICU survivors as they relate to frailty status.
  6. We are examining racial and socioeconomic outcome disparities among older survivors of critical illness.
