Biostatistics and Clinical Epidemiology Service (BCES)

The Biostatistics and Clinical Epidemiology Service was created in July 1999, and was officially announced in the October 1999 issue of Clinical Center News. Statistician Robert Wesley, PhD, and clinical epidemiologist Deloris Koziol, PhD, MPH, were the initial staff members of the new service.

The Biostatistics and Clinical Epidemiology Service:

  • Provides technical consultation and leadership on the statistical aspect of a broad range of complex medical activities, including clinical, laboratory and epidemiological research
  • Initiates, formulates, plans and executes statistical components of research studies
  • Collaborates with other scientists on the selection of appropriate study design, statistical analysis, interpretation of study results, and writing and presentation of findings

More specifically, we, BCES staff members, assist NIH investigators with the design and statistical analysis aspects of their research, i.e. we help:

  • Formulate the primary research question
  • Design the study to address the question most efficiently
  • Analyze the data to address the question most accurately
  • Publish the results most clearly and responsibly

We provide services to Clinical Center staff, fellows and interns, as well as investigators from other NIH institutes and centers. Our services range from one-hour consultations to multi-month, or even multi-year collaborations. We also teach statistics and epidemiology concepts to non-statisticians within the Clinical Center and other NIH institutes, as well as outside NIH.

Staff members:
Xiaobai Li, PhD
Ninet Sinaii, PhD, MPH

The BCES office is located in Suite 9D38 of the Magnuson Clinical Center (Building 10).
