Our laboratory's principal objective is to understand the molecular mechanism of epigenetic gene regulation and the role of epigenetics in health and disease. To address these topics, we take multidisciplinary approaches, including molecular biology, biochemistry, cell biology, structural biology and mouse molecular genetics.
