    Collapse Overview 
    Collapse overview
    I have formal training in both Biostatistics and Epidemiology, and my particular expertise is in categorical data (including longitudinal analyses), missing data, epidemiologic methods, and clinical trials. Over the past twenty years, I have helped design and implement numerous observational studies and randomized trials, with particular focus on informed decision-making, behavioral interventions, and cancer screening (colorectal, lung, and prostate).

    I have also been engaged in a wide range of educational activities:
    - development and teaching of formal courses (graduate level);
    - training of undergraduate and graduate students in (bio)statistics, public health, and other disciplines, including serving on 25+ Master's theses committees and serving as Director of Jefferson's Biostatistics Summer Internship (2015-present);
    - training of medical students, including serving as Director of Jefferson's summer research program (2013-2017) and Director of JeffMD curriculum's Scholarly Inquiry Program (2016-2020); and
    - mentoring of fellows and junior faculty.

    Professional activities:
    - Secretary/treasurer (2010-11) and Chair (2014), Section on Teaching of Statistics in Health Sciences, American Statistical Association.
    - Associate editor (2001-2012), American Journal of Epidemiology.

    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.
