Marcus was born and raised in Saxony, Germany. He graduated from the University of Technology Chemnitz (TUC) (Diploma in Chemistry, equiv M.Sc.) and completed his PhD in the group of Prof. Heinrich Lang with summa cum laude in 2017 (Fonds Scholarship 2013-2015), having studied anionic phospho-Fries rearrangements at Ferrocene and application of the resulting chiral P,O-Ferrocenes as ligands in atropselective Suzuki-Miyaura C,C cross-coupling reactions. Marcus took a position as a postdoctoral researcher at the TUC and the MERGE center of excellence. He was awarded one of three prestigious Forrest Research Fellowships and moved to the University of Western Australia in 2019. His researches focuses on the activation of small molecules and functional groups using iron half-sandwich complexes.
