Research Interests

My research interests are clinical trials in asthma, comparative effectiveness research in obstructive lung disease, and translational studies in respiratory virus infection.

I am a clinician investigator in Pulmonary Medicine with a specialized interest in asthma. With guidance of Dr. Castro who is one of the national leaders in asthma research, I have been participating in the implementation of many clinical studies, and been intricately involved with the planning, recruitment and implementation of those projects. I am actively involved in the activity of the American Lung Association Asthma Clinical Research Center network, which is one of the largest asthma networks in the U.S. and led a protocol for one of their multicenter trial called Methacholine Bronchoprovocation – influence of high potency Inhaled Corticosteroids in asthma study (MeCIS). I am leading several multi-center trials in asthma funded by NIH and pharmaceutical companies. I have been also a co-investigator in many networks including Asthmanet, and Urban Environment and Childhood Asthma (URECA) Study. I am leading the ongoing study, ASIST (Asthma Symptom-based Inhaled Steroid in African American children) funded by PCORI, which is a community-engaged pragmatic study in asthmatic children. I am also interested in administrative data research to evaluate the effectiveness or harm of an intervention in a real-life population. My translational research includes molecular detection of respiratory viruses in patients with severe respiratory diseases, and characterization of a newly discovered respiratory virus in paramyxovius family, Metapneumovirus.
