Else Kröner Fresenius Foundation awarded one of this year's Else Kröner Memorial Fellowships to HI-STEM Group Leader Mirco Friedrich. This fellowship provides two years of protected time away from clinical duties to clinician scientists to focus on their research projects. Dr. Friedrich is working on an mRNA-based strategy designed to temporarily empower the immune system, which could help overcome immune decline and enhance health-span in our aging societies.
