    Publication Field Summary
    This graph shows the number and percent of publications by field. Fields are based on how the National Library of Medicine (NLM) classifies the publications' journals and might not represent the specific topics of the publications. Note that an individual publication can be assigned to more than one field. As a result, the publication counts in this graph might add up to more than the number of publications the person has written. To see the data as text, click here.
    Publication List
    Publications listed below are automatically derived from MEDLINE/PubMed and other sources, which might result in incorrect or missing publications.
    Sort By:     Newest   |   Oldest   |   Most Cited   |   Most Discussed
    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.
