MaxNetAging was an interdisciplinary research network of the Max Planck Society that was initiated by Paul B. Baltes (former Director of the Center for Lifespan Psychology) in 2004. Many Max Planck Institutes cooperated with universities and research institutions abroad to study the causes, patterns, processes, and consequences of aging.
James W. Vaupel, Director emeritus at the Max Planck Institute for Demographic Research in Rostock, was the Director of MaxNetAging from 2007 until 2017. In 2018, he was succeeded by Mikko Myrskylä. The network included a graduate program, the MaxNetAging Research School (MNARS) that also involved the Max Planck Institute for Human Development. The program ended at the beginning of 2019.
