Juan Carlos Izpisua Belmonte is a Spanish biochemist and developmental biologist. He is a professor in the Gene Expression Laboratories at the Salk Institute for Biological Studies in La Jolla, California since 1993.

Izpisua Belmonte is a main catalyzer in one of today's most promising areas of biomedicine: regenerative medicine. His work may help to discover new molecules and specific gene/cell treatments to prevent and cure diseases affecting mankind both in the adult and embryonic stages, as well as inducing endogenous in vivo regenerative responses that may allow for tissue and organ regeneration in humans. It also may contribute to increase our knowledge of aging and aging-associated diseases, thereby leading to healthier aging and increased lifespan.
