Rainer Krebs is a postdoctoral researcher in the Cardiopulmonary Research Group. He is currently investigating the possibilities of monitoring the well-being of transplanted organs via analyis of the recipient's platelet RNA contents, as well as the transcriptomic changes in the transplanted heart immediately after reperfusion. Apart from that, he is the group's contact for handling all sorts of administrative and practical issues in research and everyday lab life.

Maria Hurskainen

Post-doctoral research fellow, MD, PhD

  • Clinical Researcher
  • Pediatrician, Fellow in Pediatric Cardiology

Maria Hurskainen wants to understand on a single cell level, how the heart is damaged and repaired. In particular, what are the cellular mechanisms driving the processes leading to allograft failure after heart transplantation? Which pathways should be targeted for prevention or to allow the heart to shift back to homeostasis? This knowledge will help to monitor and treat patients with heart transplants optimally. She also loves working in a happy team!
