Biostatistics Service Center

The Biostatistics Service Center (BSC) provides professional, high quality data analysis, biostatistical computing, and data management services to a wide range of clients in biomedical and public health research, including observational studies (epidemiologic or clinical), clinical trials, outcomes research (including studies involving large prescription and diagnostic databases), and animal studies.

Our team is comprised of Master's level statisticians, student analysts, and affiliated faculty members from the Department of Epidemiology and Biostatistics. Every project we take on is assigned to an experienced analyst.


To provide statistical expertise in support of biomedical, clinical, and public health research.


We provide statistical services on short term (per hour) or long term (within an ongoing contractual arrangement) bases. Services include:

  • Designing and analyzing strategies for research proposals involving observational, experimental, and survey research studies;
  • Conducting power calculations and sample-size estimations;
  • Selecting and implementing appropriate statistical methods for specific applications to research data;
  • Creating statistical and graphical analysis of data (graphs and tables); and
  • Contributing to and reviewing statistical components of manuscripts.

Project Structure Options

There are three options for structuring newly funded or ongoing funded projects. They are: 1) a short-term consultation, 2) a fixed percent effort contract, or 3) a task based (fixed price) contract. Selecting the best option for you is based on project scope and your preference.

In order to assess which option would be best for your project, before work on your project begins, we ask that you meet (in person, over the phone, or via Zoom) with a BSC Faculty member. This will help us to better understand your project and determine what services you will be utilizing. This initial conversation should be relatively short, and likely won’t last any longer than an hour.

Short-term consultations are best for well-defined questions with relatively small datasets; charges are made per hour, based on the numbers of hours spent working on the project. Most grant- or contract-funded projects do not include such tasks; however, sometimes there are pilot studies, interim analyses or small tasks nested within the larger study that the BSC can easily support on a short-term basis. Short term faculty services cost $120/hour plus a 30% administrative fee, for a total of $156/hour. Reduced fees will be charged for work done by other BSC staff.

Fixed percent effort contracts are generally used when the BSC provides support for funded federal, foundation, or industry sponsored projects. These can be structured as a mid- to long-term project and will involve establishing either fixed percent or fixed price contracts. With a fixed percent structure, the BSC will make staff available for a fixed percent of time. For example, 20% effort would be the equivalent of roughly 8 hours a week or 20-25 hours a month. Fixed percent effort contracts allow for more flexibility in the relationship between the investigator and the BSC staff, but it does not allow investigators to “bank” time – if effort is not used in a real-time fashion, it will not be available going forward.

Fixed price structures can be used for mid- to long-term projects, which guarantee that BSC tasks will be completed with a priori determination of the costs. With this approach, a Scope of Work is defined by the BSC Director in conjunction with the investigator. The BSC then takes responsibility for completing the set of tasks laid out in the Scope of Work. Changes can be made to the project scope with corresponding changes to the budget. The reverse, making changes first to the budget and adjusting the project scope, is also an option.


We work with researchers across Drexel University and other academic health centers, pharmaceutical companies, medical research organizations, and managed care organizations.

We continue to grow, providing expertise and services to our Drexel community, our region, and to our global neighbors.
