Stephan Roth is a Senior Scientist at DESY (Deutsches Elektronen-Synchrotron) and a Professor at KTH Royal Institute of Technology in Stockholm, Sweden. His research focuses on sustainable materials, particularly bio-based polymer materials for applications in flexible electronics, photovoltaics, and energy generation. He integrates principles of green chemistry and machine learning for advanced data analysis to develop hybrid materials from renewable resources like lignin and cellulose. His work emphasizes structure formation through nanoscale self-organization, leveraging in situ and operando experiments at synchrotron facilities worldwide. Academic Career: 2023: Professor for Scattering-Based Characterization Techniques in Fibre and Polymer Science at KTH 2022: Lead Scientist for Sustainable Materials at DESY 2016: Adjunct Professor in Synchrotron Radiation Characterization at KTH 2006–2022: Staff Scientist and Beamline Responsible at PETRA III (P03/MiNaXS) 2001: PhD in Physics from TU Munich Research Interests: Hybrid materials development, green processes in thin film technology, machine learning for materials analysis, nanostructure characterization via scattering techniques, and applications in optoelectronics, actuators, and biosensors. Key Contributions: Investigations into nanocomposite production, bio-based colloids, and structure-property relationships in functional materials. His experimental methods include synchrotron-based grazing-incidence X-ray scattering and in situ monitoring of material fabrication processes. Grants and Collaborations: Leadership in DESY’s sustainable materials program and active collaborations with institutions globally on synchrotron-based research. His work bridges fundamental materials science with industrial applications in renewable energy and biotechnology.
