Dr. Eldridge is an Assistant Professor, research track, and a cancer epidemiologist by training. He received his B.S. from Loyola University Chicago in 2008, his MPH from the Rollins School of Public Health in 2010, and his PhD from Emory University in 2014. Prior to joining the Nell Hodgson Woodruff School of Nursing, Dr. Eldridge was a Cancer Prevention Fellow in the Division of Cancer Epidemiology and Genetics at the National Cancer Institute.

Dr. Eldridge is an expert in the fields of cancer epidemiology, causal inference methods, applied statistics and data analysis. He uses his interest in advanced methods to study the biological mechanisms of cancer symptoms and survival. Currently he is involved in identifying the differential metabolic pathways of head and neck cancer survival through high-resolution metabolomics, and identifying complex longitudinal patterns in cancer patient reported outcomes that predict poor survival.
