Profile Picture

Our research is focused on understanding Aspirin Exacerbated Respiratory Disease (AERD), also known as Aspirin Sensitive Asthma or Samter’s Triad. We are investigating the causative mechanisms of AERD/Samter’s Triad, as well as exploring new treatments for the disease and working to understand how patients can become desensitized to aspirin. Our group at the Brigham and Women’s Hospital’s AERD Center follows over 900 patients with AERD/Samter’s Triad and have several ongoing research studies that are currently recruiting and enrolling patients.

We are also actively involved in research to further knowledge about the causes of chronic rhinosinusitis and nasal polyps, and to better understand the consequences of being allergic to aspirin or NSAIDs.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
