Robert Wellman joined the Group Health Research Institute Biostatistics Unit in 2009 after five years in the biostatistics core at the University of Washington’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 diagnostic test accuracy, back pain, and breast cancer. Mr. Wellman is also working with GHRI Associate Investigator Andrea Cook, PhD, to develop statistical methods for post-marketing surveillance of drugs and medical devices.
