Max Planck Institute for Ageing - Joris Deelen is leading the research group on Genetics and Biomarkers of Human Ageing at the Max Planck Institute for Ageing Research. The group studies the genetic mechanisms underlying healthy ageing in humans by investigating the effect of genetic variants that are unique to long-lived families on the functioning of pathways implicated in ageing and/or age-related diseases. Moreover, they try to identify and validate biomarkers of healthy ageing using data from large-scale international collaborations of human studies.
