John was a post-doc in Brian Oliver's lab at the National Institutes of Health for the past 4 years. During that period, he applied deep sequencing technologies (Illumina and SOLiD) to the study of gene expression, gene dose, and genomes. These technologies pave the way for genetic and evolutionary biology research in non-traditional systems. He has joined the Moriarty Lemmon lab to apply his skills in next generation sequencing, genome evolution, and biodiversity field work to study population divergence and to develop new resources for studying amphibian genomes.
