We study nutritional control of development in the roundworm Caenorhabditis elegans. We are interested in the signaling pathways and gene regulatory mechanisms that enable the worm to reversibly arrest development and resist stress in response to starvation. We are also interested in epigenetic mechanisms that mediate transgenerational effects of starvation.
