Biostatistics and Epidemiology Consulting Service

The Biostatistics and Epidemiology Consulting Service (BECS) is embedded in the GWU Department of Epidemiology and Biostatistics and provides biostatistical, epidemiological, and study design support for health-related research projects. The focus of the BECS is on the statistical needs of small to medium size observational, epidemiological and laboratory studies, as well as on small clinical trials.




The priority services of the BECS are:

  • pre-award consultation on best practices for biostatistical methods, sample size selection, and study design for health-related grant proposals; and
  • pre-award statistical analysis assistance (by faculty and/or graduate students in biostatistics and in epidemiology) of preliminary data to support a grant application.


Initially there will be no fee for these pre-award services, although it is envisioned that charge-back mechanisms will be developed over time.

For post-award services and analysis, typically the consulting biostatistician or epidemiologist would be included in the grant application as a co-investigator, and receive a negotiated percent effort to support their ongoing participation in the study should the grant application be successful. The BECS will assist investigators with developing appropriate work scopes and budget justifications as well as standard descriptions of available resources and facilities.

Non-grant related services and consultation are also available and will be provided based on faculty availability.

Please note that the Department also houses Biostatistics Core services for the District of Columbia Developmental Center for AIDS Research (DC D-CFAR), and for GWU researchers for the Clinical and Translational Science Institute at Children's National (CTSI-CN). The BECS will assist investigators to determine when one of these services is the most appropriate support option for specific grant applications.

BECS faculty also work with students enrolled in the GWU Biostatistics MPH, MS, and PhD programs, as well as the Epidemiology MS and PhD programs. Students in these programs are generally required to have supervised experience in biostatistical consultation on GWU health-related research projects. The BECS director as well as other faculty identify those projects and provide supervision for this excellent learning experience.


The core BECS faculty includes Drs. Sam Simmens (Director), Heather Hoffman, Angelo Elmi, Heather Young and Dante Verme; with other Department faculty providing support as needed. To access BECS services, please contact Dr. Simmens by email at or by phone at 202-994-7887. Dr. Simmens will help assess the nature and priority of the request and work to connect the investigator to an appropriate BECS biostatistician or epidemiologist. A formal online request form is currently being developed and will soon be posted on this website.
