Matt Kaeberlein
Dr. Matt Kaeberlein (born 1971[1]) is an American biologist and biogerontologist best known for his research on evolutionarily conserved mechanisms of aging. He is currently at the University of Washington where he is a professor in the Department of Pathology.
While a graduate student in the laboratory of Leonard Guarente at the Massachusetts Institute of Technology, he discovered that increased activity of the Sir2 enzyme increases lifespan in the budding yeast.[2]
Along with Preston Estep, Dr. Kaeberlein co-founded the human longevity research biotech company Longenity, Inc.[3]
Dr. Kaeberlein was a post-doctoral fellow in the laboratory of Dr. Stanley Fields, where he carried out genome-wide screens for genes that regulate aging in yeast.[4][5]
Along with Dr. Brian Kennedy, Kaeberlein has vocally questioned the hypothesis that lifespan extension from caloric restriction is mediated by Sirtuins.[6][7] Instead Kaeberlein and Kennedy have proposed that the caloric restriction increases lifespan by decreasing the activity of the Target of Rapamycin (TOR) kinase.[4]
