Statistical Planning and Analysis

The Statistical Planning and Analysis section provides leadership and expertise in biostatistics to collaborative research projects in Neurology. The section specializes in the design and conduct of clinical trials and observational studies, data management, and data analysis. We aim to promote rigorous and high-quality clinical and translational research.


The Statistical Planning and Analysis section is involved in collaborative research ranging from basic science to translational research and clinical trials. Our collaborative activities include providing statistical expertise for the design and analysis of multidisciplinary research projects, clinical trials, and epidemiological research and supporting the data management and analysis for multiple registries and clinical trials.


The Statistical Planning and Analysis section is committed to providing researchers with mentorship and training to improve the quality of research performed throughout the department. We conduct seminars, one-on-one training, and other educational activities intended for clinicians and researchers with all levels of research experience.


The Statistical Planning and Analysis section provides assistance in study design, data analysis, data management, and multicenter clinical trial operations. Our faculty actively contributes to many aspects of studies, including preparing grant applications, protocol development, database management, quality assurance, data analysis, and manuscript writing. We collaborate with investigators on their study design for protocols or grants, including ensuring testable hypotheses and provide sample size estimation, randomization schemes, and statistical analysis plans.

Amber Salter, Ph.D., M.P.H., is an Associate Professor of Biostatistics at UT Southwestern. She graduated from the University of Alabama at Birmingham with a Ph.D. in Biostatistics in 2015 and has a M.P.H. in Epidemiology. She holds a joint appointment in the Peter O’Donnell Jr. Brain Institute.

Dr. Salter’s research interests are in the design, analysis and interpretation of clinical trials and epidemiologic studies with a heavy focus in the area of Multiple Sclerosis (MS). She is also interested in the design and analysis of large complex databases and the issues and implications of their use in practice. She has been conducting research in the disease area of MS for over 10 years, specifically working with a disease registry, the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry, which collects self-reported data from persons with MS semiannually.
