Research Interests

The Symer research group works to identify and characterize the molecular genetics mechanisms underlying both natural variation and the formation of diseases in humans and mice. Lab members use complementary genetic and genomic approaches to study the functional consequences of endogenous mammalian retrotransposons, exogenous viruses and aberrant RNA splicing, each of which can drive extensive genomic, transcriptional, and phenotypic diversity and disease formation. They develop and use state-of-the-art techniques and assays using conventional and next generation sequencing, exon microarrays, mouse models, and bioinformatics tools. The Symer laboratory’s molecular and bioinformatics work has resulted in entirely new insights into the molecular basis for natural variation and into the molecular pathogenesis of diseases including certain cancers in human and mouse.
