The Complexity Science Hub will host a two-day workshop between its Healthcare and Medicine research group and the Copenhagen Health Complexity Center (Department of Public Health, Faculty of Health Sciences, University of Copenhagen) on Monday, September 7, and Tuesday, September 8. The workshop will bring together researchers from both institutions to explore complex systems approaches to health, spanning disease trajectories and aging, life-course epidemiology, algorithmic fairness in health, and network dynamics of health complexity. The visit marks another step in the growing collaboration between CSH Vienna and the Copenhagen Health Complexity Center and will lay the groundwork for future joint research.
