The Campisi lab studies the regulation and characteristics of cell states, with an emphasis on cellular senescence. We use simple and complex human and mouse cell cultures, intact human and mouse tissues, and mouse models to understand the molecular pathways that drive cellular senescence and other cell states. We also use genetic and pharmacological manipulations to understand how cell states cause both the degenerative diseases of aging as well as cancer and to design strategies to modulate or ameliorate their effects.
