About Meredith Ray

Meredith Ray, PhD, MPH, is an Associate Professor in the Division of Epidemiology, Biostatistics, and Environmental Health. Dr. Ray received her doctoral degree at the University of South Carolina, Arnold School of Public Health in 2014 and her MPH at the University of Georgia, College of Public Health in 2009. Her general research interests are in Bayesian methods, fMRI brain imaging analysis, bioinformatics (epigenetics) and semi-parametric modeling. Her primary research focuses on methods for identifying significant regions of brain activation using fMRI meta-data and methods for identifying associations of DNA methylation with outcomes of interest.
