A graduate of the University of Washington (UW) biostatistics program, Robert Wellman, MS, joined the Kaiser Permanente Washington Health Research Institute (KPWHRI) Biostatistics Unit in 2009. His work spans a diverse collection of topics including mental health, pharmacoepidemiology, postmarketing drug safety surveillance, obesity, diagnostic test accuracy, back pain, and breast cancer. Prior to this, he spent 5 years in the Biostatistics Core at the UW Center for AIDS Research.
