Dr. Longo is the Edna Jones Professor in Gerontology and Professor in Biological Science. He is also the Director of the USC Longevity Institute. He is interested in understanding the fundamental mechanisms of aging in yeast, mice and humans by using genetics and biochemistry techniques. He is also interested in identifying the molecular pathways conserved from simple organisms to humans that can be modulated to protect against multiple stresses and treat or prevent cancer , Alzheimer’s Disease and other diseases of aging. The focus is on the signal transduction pathways that regulate resistance to oxidative damage in yeast and mice.
