The Feinberg Laboratory studies the epigenetic basis of normal development and disease, including cancer, aging and neuropsychiatric illness. Early work from our group involved the discovery of altered DNA methylation in cancer as well as common epigenetic (methylation and imprinting) variants in the population that may be responsible for a significant population-attributable risk of cancer.
Over the last few years, we have pioneered the field of epigenomics (i.e., epigenetics at a genome-scale level), founding the first NIH-supported NIH epigenome center in the country and developing many novel tools for molecular and statistical analysis. Current research examines the mechanisms of epigenetic modification, the epigenetic basis of cancer, the invention of new molecular, statistical, and epidemiological tools for genome-scale epigenetics and the epigenetic basis of neuropsychiatric disease, including schizophrenia and autism.
Seth Margolis Laboratory
The Seth Margolis Laboratory studies the signaling pathways that regulate synapse formation during normal brain development to try to understand how, when these pathways go awry, human cognitive disorders develop.
We use Ephexin5 to study the molecular pathways that regulate restriction of excitatory synapse formation and their relevance to the pathophysiology of Angelman syndrome.
