Biostatistics & Design Program

Mt. Adams

About us

Our mission is to facilitate collaboration with investigators on questions of study design and analysis. BDP faculty and staff have experience in a wide range of content areas in the health sciences, and are experts in the design of clinical trials, clinical and community-based intervention studies, laboratory experiments, and observational studies. We help investigators select the most appropriate study design to align with their research questions.

Our group has expertise in a wide variety of traditional and modern statistical methods. We can help with trial design and analysis, epidemiologic analysis, sample size and power, high-dimensional data analysis, risk prediction, complex survey analysis, time-to-event and longitudinal models, and statistical simulation.

The BDP also does data management and wrangling, analytic variable coding and data set creation, research database design, data visualization, manuscript preparation, statistical programming, and much more. We coordinate with our colleagues in other cores that generate and process data when projects require it—such as the Bioinformatics Core, the Knight Biostatistics Shared Resource, REDCap, the Research Data Warehouse, and the Evaluation Core, among others.

We encourage researchers to consult with the BDP as early as possible and to work with a biostatistician when designing studies and developing statistical analysis plans.

What we do

  • Advice Sessions: Discussion of statistical questions scheduled for approximately an hour, free of charge. These sessions, sponsored by OCTRI-BERD, tend to book a few weeks out. Please contact us ahead of time to reserve your spot.
  • “Triage”: Detailed conversations leading to a recommendation for biostatistics support tailored to research aims, budget, and timeline.
  • Grant preparation: Proposal development, study design, statistical analysis planning, sample size and power analysis.
  • Protocol development: Statistical analysis planning, review of study instruments or survey implementation, sampling and randomization schemes.
  • Active research: Analysis of data, including designing an approach, interim analysis, analytic file preparation, design of tables and figures, collaboration on abstracts, posters, and manuscripts.

Acknowledging BDP

To give general acknowledgment to BDP for guidance on a manuscript received during Advice Sessions, please include this text in the Acknowledgments: “We would like to thank the OHSU Biostatistics & Design Program (supported by the OHSU University Shared Resources Program and UL1TR002369 [OHSU CTSA grant]) for data analysis expertise.”

Note, you may additionally acknowledge the analyst with whom you met in the Advice Session for their assistance. If you include the name of the analyst in your manuscript, please reach out to the analyst (or to to allow for review. If you do not recall the name of the analyst with whom you spoke, please reach out to BDP.


We are partially funded by the Oregon Clinical & Translational Research Institute (OCTRI)’s Biostatistics, Epidemiology, and Research Design (BERD) Program, which hosts a series of workshops on a variety of topics as part of the OCTRI Research Forum. See upcoming BERD workshops and consider joining us at the next one.


  • Fees for short-term collaborations lasting weeks or months are based on projected effort needed to complete the scope of work in the time frame specified. These projects have distinct goals and deadlines.
  • Longer-term collaborations can be funded by FTE on grants or contracts.


Contact us by emailing to discuss your needs—we can work with you to determine the scope of statistical support required for your project or grant application, or schedule an advice session for you.
