01:18:22 Share

In this episode of Longevity by Design, host Dr. Gil Blander is joined by Dr. Morten Scheibye-Knudsen, a leading figure in aging research. Dr. Scheibye-Knudsen discusses his groundbreaking research on the role of DNA damage in the aging process and its implications for chronic diseases, aging research, and longevity medicine. The goal of his work is "to discover interventions leading to healthier, happier, and more productive lives."

Dr. Scheibye-Knudsen's work is on understanding normal and premature aging, with a focus on the pivotal role of DNA damage in the aging process and interventions for healthier aging. By combining computational methods with laboratory experiments, his team explores innovative strategies to target DNA and counteract aging processes. This conversation illuminates the intricate relationship between DNA damage, aging, and chronic diseases. 

Dr. Scheibye-Knudsen also discusses the impact of lifestyle (diet, exercise, sleep, social factors) on aging. He goes on to describe his work using data-driven approaches to better understand aging and developing interventions, including identifying novel targets and drugs, for healthier aging. Additionally, he explains what longevity medicine is and the importance of educating clinicians and politicians on this topic to translate research on aging into healthcare and improve people’s healthspan and lifespan. Dr. Scheibye-Knudsen's dedication to unraveling the mysteries of aging is advancing scientific knowledge, which has tangible benefits for global health and longevity.
