We use the roundworm Caenorhabditis elegans as model to investigate how animals cope with fluctuations in food availability. We are interested in the signaling pathways and gene regulatory mechanisms that enable this worm to reversibly arrest development and endure starvation. We are interested in adaptation to nutrient stress over different time scalse, including nongenetic inheritance and multigenerational phenotypic plasticity.

Research Description: 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 investigating epigenetic mechanisms responsible for transgenerational effects of starvation.

Areas of Interest:
nutritional control of development
gene regulation
insulin signaling
aging
