I am an epidemiologist with broad interests across the cancer care continuum. As a Senior Scientific Investigator at Kaiser Permanente Washington Health Research Institute (KPWHRI), 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.
