Marcus Krüger received his doctorate in molecular biology from the University of Erlangen-Nürnberg in 2009. His doctoral studies were focused on the signal transduction inside the bacterial tetracycline repressor TetR. Thereafter, he worked as a lecturer and research associate at the Faculty of Sciences in Erlangen, where he started to investigate the effects of physical and chemical influences on cells. Since 2016, he has been a senior scientist at the University of Magdeburg in the field of space medicine. His current main interests are cancer research and tissue engineering under microgravity conditions, particularly in finding new targets for cancer therapies using tissue-engineered cancer constructs. He has more than 77 scientific international papers with an h index factor of 25 and more than 1600 citations to his work (Scopus, 22 December 2023).
