High Temperature Corrosion

"We combine fundamental research with the real conditions in industry. Our many years of experience and understanding of processes and mechanisms enable us to quickly plan and develop solutions for our customers."


since 2017

Member of the Institute Directorate of the DECHEMA Research Institute


Habilitation at the University of Bayreuth, Germany; Lectures on corrosion, high-temperature corrosion and coating technology

since 2012

Head of the working group "High-Temperature Materials" of the DECHEMA Research Institute, Frankfurt am Main, Germany


Junior scientist in the working group "High-Temperature Corrosion" at the Karl-Winnacker-Institut of DECHEMA e.V., Frankfurt am Main, Germany


PhD at the University of Bayreuth, Germany "Influence of Temperature on Friction and Deformation Mechanisms in Artificial Knee Joints" (1.0 - Magna cum laude)


Degree in materials science at the University of Bayreuth, Germany

Main Areas of Research

  • High temperature corrosion (sulfidation, metal dusting, coating and molten salt corrosion)
  • New materials for high-temperature applications (chromium-based, titanium aluminides, abrasion-resistant high-temperature coatings)
  • Development of diffusion coatings (pack cementation, slurry coatings)
  • Lifetime prediction/modeling of coatings
  • Innovative concepts for protection against aggressive atmospheres such as vanadates and solar salt melts
