Boston University School of Public HealthPhDHealth Services Research

I'm a health services researcher committed to improving healthcare for people with rare diseases by leveraging information collected directly from patients and their family members. My research focus is improving the accessibility, quality, and patient-centeredness of care for patients with the neurofibromatoses. To do this, I use qualitative and mixed methods to understand patients healthcare needs and experiences; I develop and use patient reported outcome measures for use in clinical trials; and I engage patients as partners in the design and conduct of my research. I am highly experienced in neurofibromatosis 1, neurofibromatosis 2, and schwannomatosis, and have broad interests across neurology and oncology.

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.
