A graduate of the University of Washington’s (UW) biostatistics program, Robert Wellman, MS, joined the Kaiser Permanente Washington Health Research Institute (KPWHRI) Biostatistics Unit in 2009 after five years in the biostatistics core at UW’s Center for AIDS Research. From 2006 to 2009, his work was supported in part by an HIV/AIDS national research service award sponsored by the U.S. Department of Health and Human Services. His work now spans a diverse collection of topics, including pharmaco-epidemiology, post-marketing drug safety surveillance, diagnostic test accuracy, back pain, and breast cancer.
Mr. Wellman currently serves as an analyst for the Statistical Coordinating Center of the National Cancer Institute’s Breast Cancer Surveillance Consortium, working on collaborative research projects utilizing data from seven mammography registries in the United States. Mr. Wellman is also working with KPWHRI Associate Investigator Andrea Cook, PhD, to develop statistical methods for post-marketing surveillance of drugs and medical devices in large distributed data settings as part of the Food and Drug Administration’s Mini-Sentinel initiative.
