Carl and Hazel Felt Laboratory for Pulmonary Research

Established in 1988, the mission of the Carl and Hazel Felt Laboratory for Pulmonary Research is to advance the understanding of asthma pathogenesis, including the study of new and current therapies. We hope to accomplish these goals by studying people with asthma to learn how airway inflammation begins, continues and responds to therapy. We are endeavoring to apply the concepts learned at the bench to patient care, in hopes of improving asthma therapy and ultimately quality of life.



Our research group is a select part of a multi-center network funded by the National Institutes of Health's (NIH) National Heart, Lung and Blood Institute (NHLBI). AsthmaNet is dedicated to developing and carrying out research on asthma and the best treatments for it.

Steroid Resistance and Asthma

One of the common treatments for asthma is corticosteroids. These medications usually reduce airway inflammation and improve asthma control. However, there are many asthmatics who have little to no improvement with corticosteroids. We are investigating the mechanisms involved in this varied response to medication.

Obesity and Airway Disease

Evidence has been accruing suggesting obesity as a risk factor for asthma. We are currently examining the effects of body mass index (BMI) on lung function and asthma control.


Our research group specializes in utilizing bronchoscopy for some of our research studies. Using this fiberoptic scope allows for direct evaluation and collection of small samples from the airways. In the laboratory, these samples can be analyzed and the results used to explore asthma biology and response to therapy.
