Personal profile

Research interests

My research interests are clinical trials in asthma, comparative effectiveness research in obstructive lung disease, stakeholder engagement in research, and translational studies in respiratory virus infection. I have been actively engaged in the conduct of multiple national clinical research networks including American Lung Association Asthma Clinical Research Center network, NIH-funded networks, including Severe Asthma Research Program and PrecICE (Precision Interventions for Severe and/or Exacerbation-Prone Asthma) network, and Pulmonary trials cooperatives participating in their trials as a site PI and Co-investigator. I led the ASIST (Asthma Symptom-based Inhaled Steroid in African American children: funded by PCORI), a community-engaged pragmatic study in asthmatic children working with community pediatricians in Saint Louis. The result of this study is now included in a well-sited international asthma guideline (Global Initiative in Asthma: GINA).

My recent interest also involves implementation of as-needed inhaled steroids in asthma in the community setting, and patient and stakeholder engagement in research

Clinical interests

I lead the severe asthma clinic at Washington University Lung Center, deeply engaged in the delivery of quality care to improve the lives of patients with uncontrolled asthma. Also leading management of severe asthma patients at St. Louis VA Medical Center.
