Research Overview

Dr. Erickson serves as statistical geneticist in ACHRI’s Center for Birth Defects Research and Prevention and is assistant professor in the UAMS Departments of Pediatrics and Biostatistics.  He is currently investigating the genetic and environmental factors influencing congenital heart defects and other birth defects.

Dr. Erickson received his doctorate in statistics from UCLA and, in the spring of 2009, completed a postdoctoral fellowship with the Section on Statistical Genetics in the Department of Biostatistics of the University of Alabama at Birmingham (UAB).  He has extensive experience in the analysis of genomic microarrays, including the inference of DNA copy number variation (CNV) from genotyping array data.  Dr. Erickson’s methodological research focuses on empirical and hierarchical Bayes models.
