Clinical Research

Richard Barbers, MD
Dr. Barbers’ research explores how abnormal repair processes (which include inflammatory and immune mechanisms) eventually lead to airway fibrosis (remodeling) in asthma. He is also collaborating with Dr. Omid Akbari’s laboratory to search out the role of innate and adaptive immunity in asthma as well as to search out the role of autophagy (repair and regeneration of cells) in this very common disease.

Ahmet Baydur, MD
Dr. Baydur’s research investigates changes in respiratory physiology that occur in patients with cardiovascular and ventilatory disorders such as chronic obstructive pulmonary disease (COPD) and asthma. He is also interested in learning whether linking the results of lung imaging, pulmonary function studies and transbronchial lung biopsies better predict outcomes of patients experiencing chronic rejection of their transplanted lung.

Richard Castriotta, MD
Dr. Castriotta’s research activities are focused on the interaction of heart and lung function during sleep in health and disease.

Ching-Fei Chang, MD
Dr. Chang studies the diagnostic yield and cost-effectiveness of new bronchoscopic and pleural interventions. She is also interested in learning whether lung cancer outcomes differ in patient populations with health care disparities. 

Sivagini Ganesh, MD
Dr. Ganesh is involved in many multi-centered drug studies looking for better ways to treat patients with pulmonary hypertension, pulmonary fibrosis, or both. She is also conducting investigator-initiated studies that seek better treatment options for patients with pulmonary hypertension or lung transplantation.

Aarya Kafi, MD
Dr. Kafi is involved in multi-centered drug studies that are directed at finding better treatments for patients with pulmonary fibrosis. He is also interested learning whether there are better ways to minimize complications associated with immunosuppression in lung transplant patients.

Santhi Iyer-Kumar, MD
Dr. Iyer-Kumar is involved in the study and implementation of best practices within the ICU and in health systems to improve patient safety and optimize care delivery. 

May Lee, MD
Dr. Lee’s clinical research interests are in critical care medicine as well as graduate medical education. 

Janice Liebler, MD
Dr. Liebler is interested in identifying sub-populations of patients in the critical care unit who are at an increased risk for adverse outcomes. She is also involved in several multi-centered clinical research studies, including one that will attempt to discover the best ways to transition patients from mechanical ventilation to spontaneous breathing.

Brett Lindgren, DO
Dr. Lindgren is interested in studying the outcomes of various kinds of treatments that are frequently utilized in the critical care unit. He is also interested in optimizing patient care in advanced bronchoscopy procedures.

Adupa Purush Rao, MD
Dr. Rao’s research activities are focused on improving the outcomes for patients with cystic fibrosis. He is participating in several multi-centered studies, as well as investigator-initiated studies, toward achieving that goal.

Bassam Yaghmour, MD
Dr. Yaghmour’s clinical research is focused on describing the physiologic abnormalities that are caused by pulmonary hypertension using measurements from cardiopulmonary exercise testing (CPET) before and after treatment. He is also interested in investigating innovative medical treatments for pulmonary hypertension.
