The Office of Research Services (ORS) helps faculty, learners and staff effectively use data throughout all stages of the research process. We encourage investigators to contact ORS about any data analysis questions early in the research process.

Requesting Data

The UW Clinical & Health Informatics Institute (CHI2) assists investigators during project conceptualization, grant submission, and deployment of secure data storage and processing methods.

For assistance, complete the CHI2 Data Request & Consultation form.

Biostatistical Analyses

The Department of Medicine's Biostatistics Consulting Service promotes excellence in medical research by providing department faculty and trainees support and collaboration in the design, conduct and analysis of basic, clinical and population-based research studies.

Statistical consultation is especially valuable during the planning stage of a research study or a proposal for extramural funding. The involvement of biostatisticians in data analyses strengthens the credibility of the study findings in the medical research community.

All DOM faculty and trainees have access to the services below at no charge. The department encourages addition of percent effort for a biostatistician in your grant, but this is not a requirement to receive statistical services.

For Junior Faculty, Fellows and Trainees: DOM Biostatistician

The DOM biostatistician assists the statistical work of junior faculty, fellows and trainees in the department. Please contact the biostatistician early in the process of developing an idea or project design.
