Biography

Stephan Volkher Roth is a Professor at KTH Royal Institute of Technology, engaged in research on functionalized polymeric materials based on bio-sources. His work is framed within the sustainability framework, focusing on renewable materials that facilitate greener processes and energy harvesting, employing principles of green chemistry and machine learning. His current research includes the development of novel hybrid materials for optoelectronic applications derived from advanced bio-derived core-shell colloids and flexible solar cells for thermoelectric applications. Roth also investigates advanced biosensors using (bio)polymer-inorganic colloid hybrid materials for lithographic applications, emphasizing self-assembly for nanostructuring. His research employs X-ray and neutron scattering at large scale facilities to establish the nanostructure-function relationship of hybrid materials through real-time in-situ operando experiments. His work spans various deposition methods of thin films such as spray coating and vacuum deposition.
