Research Overview

  • RNA modification and translation regulation
  • Neurodevelopmental disorders linked to RNA function
  • Biochemistry and molecular biology

Our laboratory investigates the cellular roles of nucleic acid modification enzymes in biological processes ranging from neurodevelopment to the cellular stress response. In particular, we focus on discovering the targets and functions of two classes of enzymes: the SAM-dependent methyltransferases and the iron-dependent AlkB dioxygenases. To study the diverse processes modulated by these enzymes, we use an integrated biochemical, molecular and genetic approach in mammalian tissue culture systems as well as mouse knockout models. Through this approach, we have discovered novel targets and functions for enzymes involved in DNA repair, RNA modification and regulated cell death. The pathways and mechanisms identified through our studies provide critical insight into multiple aspects of human health and disease, including anti-cancer chemotherapy, degenerative disorders and aging.
