Randall Johnson, Ph.D.

 National Cancer Institute at Frederick 

Building 560:11-85 
Frederick, MD 21702-1201 U.S.A. 

Hours: Office Hours


Randall received two B.S. degrees from Utah State University in Statistics and Computational Mathematics in 2003, an MHS degree from the Johns Hopkins School of Public Health in 2005 and his PhD in Bioinformatics from the Conservatiore National des Arts et Metièr in 2013. His dissertation focused on the modeling of linkage disequilibrium in whole genome genetic association studies and was completed under Dr Cheryl Winkler, head of the Molecular Genetic Epidemiology Studies Section of the Basic Research Laboratory at the National Cancer institute. Starting in 2004, he has been working as a contractor for Leidos Biomedical Research at the Laboratory of Genomic Diversity (2004-2010) and the BSP CCR Genetics Core (2010-Present) at the National Cancer Institute in Frederick Maryland, providing statistical and technical support to researchers at the Center for Cancer Research.


I am interested in statistical problems encountered in the analysis of admixed populations and the effect of microbiome communities on health.
