Office of Biostatistics

The Office of Biostatistics is currently recruiting Statisticians (MS and PhD level) for available positions within all of its Biometrics divisions.

The Office of Biostatistics is recognized for excellence in the application and communication of statistical science in drug regulation and development. We play a central role in promoting innovative, science-based, quantitative decision-making throughout the drug development life-cycle. To support CDER’s mission, we provide statistical leadership, expertise, and advice to ensure that safe and effective drugs are available to the American people.

What We Do

  • Ensure the safety and effectiveness of new drugs, therapeutic biologics, generic drugs, over the counter products, and biosimilar products through pre-market review of drug development programs. Key aspects of our statistical review are to:
    • Evaluate the appropriateness of proposed trial designs and analysis plans
    • Check for data accuracy, quality, and completeness
    • Determine the validity of sponsor’s analyses and interpretability of results
    • Assess the robustness of results to check impact of unverifiable assumptions
    • Evaluate results in light of evidentiary standards
    • Assess risk and benefit to support product approval
  • Ensure the safety of marketed drugs through:
    • Development of statistical methods for post-market surveillance
    • Review of post-market safety studies
  • Provide leadership and statistical support for CDER and FDA programs such as
    • Analysis Data Standards
    • Complex Innovative Designs
    • Patient Focused Drug Development (PFDD)
    • Real World Data (RWD)/ Real World Evidence (RWE)
    • Rare Diseases
    • Digital Health Technologies (DHT)
  • Develop and disseminate statistical policy and guidance.
  • Advance statistical science through research, publications, and training

FDA Statistical Research

Our statisticians conduct independent research on statistical methodologies relevant to CDER’s scientific mission and regulatory review process. Our research spans such broad areas as clinical trial design, Bayesian statistics, signal detection, causal inference, meta-analysis, bioequivalence, benefit-risk assessment, patient focused drug development, psychometrics, and product quality assessment and control.

Recent Statistical Guidance Documents

Work with Us

Advisory Committee Membership

Advisory Committees provide FDA with independent opinions and recommendations on applications to market new drugs, and on FDA policies. The Committees meet publicly to discuss and weigh in on matters for which FDA seeks advice. Committees are organized by both therapeutic areas and across therapeutic areas (e.g. drug safety).

Committee memberships consist of a range of subject matter experts, including clinicians, pharmacists, patient representatives, and statisticians.

Expert statisticians interested in learning more about the role of Members or Consultant to CDER Advisory Committees should contact the Office of Biostatistics Director, Dr. Sylva Collins.

Office of Biostatistics Recruitment Program

The Office of Biostatistics recruits statisticians through a continuous search for qualified master’s and doctoral degree candidates who are interested in the areas of statistical programming (Statistical Analyst) and statistical methods in clinical trial conduct and evaluation, risk assessment, and pharmacovigilance (Statistical Reviewers).

Working as a regulatory statistician offers an exceptional way of gaining experience in:

  • regulatory statistical issues
  • diverse methodologies
  • clinical trial design
  • drug indications

New regulatory statisticians are mentored by highly trained statisticians and collaborate with other regulatory scientists on an ongoing basis. They engage in scientific and regulatory research and participate in professional societies and associations. Research efforts may be supported through grants.

Most importantly, regulatory statisticians serve to protect the American public by ensuring that safe and effective drugs are available.

Information on employment with the Food and Drug Administration is available on both the FDA and CDER web sites.

Additional information may be obtained by emailing The Office of Biostatistics Recruitment Committee at CDEROTSHires@fda.hhs.gov.

Opportunities for Students and Recent Graduates

The Office of Biostatistics participates in the Oak Ridge Institute for Science and Education (ORISE) Research Participation Training Program. The goal of this program is to provide practical scientific training for scientists and physicians through the performance of scientific projects at the FDA. All of the projects will be relevant to the mission of the FDA. Additional information may be obtained here.
