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.
