The Department of Biostatistics is one of 5 departments in the School of Public Health and Community Medicine at the University of Washington. Its mission is to serve as a source of expertise and a focus for training and research in the quantitative aspects of public health and medicine, and to promote the use of rigorous quantitative methods in the biomedical and public health sciences.

Our graduate program is regarded as one of the best Biostatistics programs in the world, with over 30 years of teaching and research experience on the UW campus. Faculty interests range over a wide variety of statistical topics, including survival analysis, clinical trials, statistical genetics and correlated data.

The UW Biostatistics Working Paper series includes articles on statistical methods and applications developed by members of the department. In general, articles dated 2000 and later are downloadable from this site.
