Carlos López-Otín (Spain) is an award-winning Professor of Biochemistry and Molecular Biology at the University of Oviedo. He is an authority on the subject of cancer and aging thanks to his advanced studies into human genetics, and also the discoverer of more than 60 new genes, as well as of two accelerated aging syndromes and pro-longevity bacteria. His books La vida en cuatro letras (2019), El sueño del tiempo (2020) and Egoístas, inmortales y viajeras (2021) constitute his brilliant trilogy of life, in which he covers questions with both biological and philosophical perspectives including the relationship between genetics, disease and happiness; time, biology and technology; and the nature of a disease as complex as cancer. Carlos López-Otín shared his fascinating vision in conversation with Hernando Baquero, pediatrician and dean of the Department of Health Sciences at Universidad del Norte, and María del Pilar Garavito, geneticist and teacher at Universidad del Norte.
