DENNIS HAZELETT LABORATORY
Originally trained as a geneticist in the field of developmental biology, I have a broad background in both experimental and computational biology. I rely on a systems-biology approach involving the analysis and synthesis of next-generation sequencing data. My most recent contributions are highlighted by efforts to annotate and draw inference from the functional consequences of genetic associations from genome-wide association studies (GWAS) for prostate cancer, Hodgkins lymphoma and ovarian cancers. Toward this goal, I integrated GWAS and next-generation sequencing data from my collaborators with public datasets such as1000 genomes and the Encyclopedia of DNA elements (ENCODE) to infer new diseases variants outside of transcribed sequences. I have recently begun independent efforts as a principle investigator at Cedars-Sinai Medical Center, using novel approaches to achieve a greater understanding of the relationship between the regulatory code and genetic disease variants.
