      Collapse Overview
      Dr. Harold R. Collard is an associate professor of medicine in UCSF's Division of Pulmonary and Critical Care Medicine and the Director of the Interstitial Lung Disease Program at UCSF. His primary interest is in the management of patients with interstitial lung disease, including how best to diagnose and treat interstitial lung disease and how the condition impacts a patient's quality of life and survival.

      Dr. Collard earned a medical degree at Duke University. He completed an internship, residency and chief residency in internal medicine at UCSF as well as a fellowship in pulmonary and critical care medicine at the University of Colorado. Prior to joining UCSF, Dr. Collard was a member of the Interstitial Lung Disease Program at the National Jewish Medical and Research Center in Denver. Dr. Collard regularly sees patients with interstitial lung disease as part of the UCSF Interstitial Lung Disease Clinic (415-353-2577 (phone), http://www.ucsfhealth.org/ild).

      Research Interests

      Dr. Collard is a clinical and translational researcher focused on patients and populations of patients with interstitial lung disease. Dr. Collard is currently conducting projects investigating: (1) acute exacerbations of idiopathic pulmonary fibrosis (acute events that cause significant worsening of disease for many patients); (2) predicting disease progression (3) factors contributing to patients’ symptoms of shortness of breath and ways to improve patients’ quality of life; (4) clinical trials of promising but unproven therapies for patients with interstitial lung disease. Dr. Collard also supervises the UCSF ILD Program clinical database which contains data from over 1500 patients with various forms of interstitial lung disease.
