Biostatistical Research Group

Biostatistical Department

The UTHSC College of Medicine Chattanooga Office of Research has established a Biostatistical Department to assist researchers with sample size calculations, methodology as well as data analysis and manuscript writing. 

Initial Biostatistical review takes place within the IRBNet system.  Once a new project is submitted with required documents in IRBNet, the project will then be sent to one of the Biostatisticians for review.  Directions on how to register for IRBNet and create and submit a new project is located at the IRB Guidance Documents and Policies page. The link to the IRBNet site is www.irbnet.org.

If you have any questions regarding Biostatistical review, you may contact Stacey Hendricks, CIM at Stacey.hendricks@erlanger.org or 423.778.3818, or through IRBNet Project Email.
