We study epigenetic regulatory networks associated with cell specification and disease development. Toward this goal, we emphasize the development of novel high-throughput experimental approaches and the implementation of computational tools for -omics data analysis. Over the last decade, we have investigated the epigenetic programming mechanisms with stem cells and for tissues of the brain and blood.
