We investigate the signaling pathways associated with cellular aging.
Our research centers around cellular aging in normal and disease states, with a particular focus on the molecular and cellular pathogenesis of premature aging diseases such as Hutchinson-Gilford progeria syndrome (HGPS). As means, we combine molecular, cellular biology, genetics, and proteomics to identify signaling pathways associated to cellular aging to develop preventive strategies to delay and/or correct aging processes.
