I am an epidemiologist with broad interests across the cancer care continuum. As an Associate Scientific Investigator at Group Health Research Institute (GHRI), I lead and participate in studies of cancer screening and outcomes. I have experience working in large research networks and with automated data, chart review, and patient-reported outcomes.
