This week Patrick is joined by Austin Argentieri, Research Fellow at Harvard Medical School, Affiliate Member of the Broad Institute of MIT and Harvard, and Research Fellow at Massachusetts General Hospital. Austin’s work focuses on the proteomics of aging and how proteomic signatures are highly predictive for estimating biological age. From the potential of therapeutic applications, to why no “fountain of youth” genes have yet been identified, he and Patrick discuss the heritability of aging and how proteomics can help identify risk of age-related disease.
