Joan Warren, PhD, has been an Epidemiologist in the Health Services and Economics Branch of the Applied Research Program since 1998. Dr. Warren received her BS in Nursing from Georgetown University and worked for 10 years in a variety of acute care and community settings prior to returning to graduate school. She received her PhD in Health Policy from the University of Maryland in 1989. In that same year, she joined the Epidemiology Branch in the Office of Research at the Center for Medicare and Medicaid Services (then HCFA). During her eight years at CMS, she worked extensively with Medicare claims, learning how to use these data for a range of health services research projects. Upon coming to NCI, she assumed responsibility for the management of the SEER-Medicare data, a file that links Medicare eligible persons in the SEER data with their Medicare claims. Dr. Warren's research has focused on the use of secondary data, such as the SEER-Medicare files, to assess patterns, outcomes, and costs of care. She has also worked extensively with researchers from government and academic settings to promote standardization of measures and methods using secondary data. Dr. Warren has published numerous papers in these research areas. She serves as NCI Program Director for the Program Announcement "Using Health Claims Data for Cancer Surveillance", which provides support for projects using the SEER-Medicare and related data sources.
