PD Dr. Andreas Zietzer studied medicine at Charité – Universitätsmedizin Berlin, where he finished his translational doctorate in 2017. In 2016, he transitioned to the Heart Center at the University Hospital Bonn to join the BONFOR program there. His early post-doctoral research focused on endothelial regeneration and the cardiovascular impact of kidney disease, securing funding from the German Society of Cardiology.
