The Biostatistics and Risk Assessment Center (BRAC) is located in the School of Public Health of the University of Maryland at College Park. Our mission is to foster and conduct statistical analysis, data mining, and quantitative risk assessments in areas of public health and biomedical research.

Department: Epidemiology and Biostatistics 
Room Number: 2234R
Director: Mei-Ling

Office Phone Number: (301) 405-4581

The primary goal of BRAC is to collaborate with investigators and research institutions in undertaking statistical analysis, bioinformatic procedures, and quantitative risk assessment. Our objectives are:

  • To collaborate with investigators and provide help on study design, sample size and power calculations, data collection and data management, statistical modeling, bioinformatic analysis, interpretation of statistical findings, manuscript preparation, and dissemination of results.
  • To take the lead on the development of new and improved biostatistical and bioinformatic methods which are needed for cutting-edge multidisciplinary and translational research.
  • To develop software tools for new statistical methods developed for the projects.

Data Center

The Biostatistics and Risk Assessment Center serves as the data center for several research projects. Our data center services include data collection, data management, data storage, and data analysis.

We have a Dell PowerEdge T310 server with an Intel Xeon X3460 Quad-Core Processor and 32GB of RAM Memory. The speed of the processor is 2.8 GHz and has 8MB of cache memory. The server’s hard disk storage capacity is 2 Terabytes (2000 Gigabytes). The data are automatically backed up. The hardware is controlled by a Red Hat Enterprise Linux 5.3 (64 bits) network operating system with an active license. The computer has been working as a web server (Apache Server). We have several database management systems, including MySQL. We will discuss with the investigators their needs and use the most appropriate database management system for their projects.
