Stefan Naumann received his diploma in chemistry from the University of Stuttgart in 2010, working on metathesis-derived conjugated polymers. This was followed by PhD studies under the guidance of Prof. M. R. Buchmeiser, investigating protected N-heterocyclic carbenes (NHCs) for thermally latent polymerization processes, which included applications for acrylate-based monomers, polyamide production, polyether and polyester synthesis, as well as the preparation of polysiloxanes and epoxy resins. Special emphasis was put on larger scale preparation and practicability, which resulted among others in novel methods to generate epoxy resin-based composite materials and “on demand” 1K polymerization systems. After finishing his PhD in 2014, he was granted a DFG research stipend and joined the group of Prof. Andrew P. Dove at the University of Warwick (UK). There, he focused on novel ways to catalyze polymerization reactions, including the development of N-heterocyclic olefins (NHOs) and high-performing dual catalytic setups. Returning to Stuttgart in 2015, he started a habilitation process embedded in the Buchmeiser group. His current research interests encompass polymerization catalysis (organocatalysis, dual catalysis, organometallic single-site complexes) and the preparation of mesoporous polymer/carbon materials for multiple purposes.
