Sara Gelino is interested in the role of autophagy in the longevity pathway of dietary restriction. Dietary restriction, or limited food intake without malnutrition, is known to extend the lifespan of many organisms. However, the cellular mechanisms underlying this fascinating phenomenon are still poorly understood. Using the nematode C. elegans Sara is working to address how autophagy promotes C. elegans longevity at the cellular and molecular level during dietary restriction.
