Johannes attended the University of Basel, Switzerland, where he earned his M.Sc. in 2012. After research stays in the group of Prof. Dr. Donna G. Blackmond at The Scripps Research Institute and the Institute for BioMedical Research at Novartis, Basel, he moved to Munich to pursue his Ph.D. with Prof. Dr. Thorsten Bach at the TU München. His doctoral endeavors dealt with pyrrole synthesis and their application as a directing group for C-H alkylation. Upon completion of his graduate studies, he moved to Indiana University to work with Prof. Dr. M. Kevin Brown on natural product synthesis as a DFG-funded post-doctoral fellow. During that time, he completed the first enantioselective synthesis of the sesquiterpene hebelophyllene E. Johannes started his independent career at the Universität Münster.
