                                                                                                      Julian Marschner is a postdoctoral fellow at the Department of Medicine IV of the University Hospital, LMU Munich. He works on pre-clinical in vitro and in vivo models of acute kidney injury (AKI) and chronic kidney disease (CKD), thereby focusing on the interplay between the immune system and the renal parenchyme in mechanisms of tissue injury and regeneration. Specifically, his research looks into the role of soluble receptors of the immune system (e.g. PTX3, NLRP3) in non-immune cells of the kidney and the contribution to the progression of kidney disease. He further puts emphasis on the development of sophisticated cell culture models to mimic key aspects of AKI and CKD, and the development of therapeutic strategies to foster parenchymal recovery after injury.

                                                                                                      Julian Marschner ended his studies in Geography and Environmental Sciences with a strong focus on the impact of human actions on forestal and edaphic processes, qualifying with a BSc in 2009. This prompted him to widen his scope on the interplay between man and nature on a molecular level, which led him to further study Environmenal Toxicology, finishing with a MSc in 2013. His education at the University of Trier focused his interest on the role of the mammalian immune system in developing adverse reactions to human- and nature-derived small molecules.

                                                                                                      Having identified studies on the mammalian immune system as a passion, he sought to deepen his knowledge in the field by getting in touch with clinical aspects of immunity. In doing so he enrolled at Hans-Joachim Anders group as a PhD student in 2013 and studied the contribution of the immune system to various pre-clinical models of AKI and CKD in the subsequent years, qualifying for a doctoral degree in 2019.

                                                                                                      From there on he continued working with Prof. Anders on questions of renal injury and regeneration in pre-clinical models of kidney disease as a Postdoctoral fellow. His primary focus lies in identifying potential therapeutic targets and validating respective experimental interventions in the context of acute and chronic kidney disease.
