Stephan Völker is Professor and Chair for Lighting Technology at Technische Universität Berlin. His research includes investigations into brightness perception, light and radiation measurement, light and thermal comfort and the characterization of daylight. Völker studied electrical engineering and lighting engineering at Technische Universität Ilmenau and holds a PhD from that institution. He has previously held posts at University College London, Universität Paderborn and Technische Universität Ilmenau as well as industry experience at the firm Hella KG. Völker has received research grants from the Federal Ministry for Traffic and Digital Infrastructure, the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety, the Federal Ministry for Economic Affairs and Energy and the Federal Ministry for Education and Research as well as a fellowship from the Konrad-Adenauer-Foundation. His innovative research has been recognized through prizes including the “Deutscher Verkehrssicherheitspreis” (German Traffic Safety Award) and the Helwig Award for Professorial Dissertation. Völker is a member of the German Society of Lighting (LiTG), the LiTG Technical Scientific Committee, the LiTG expert forum “External Lighting,” the Technical Committee‚ Mesopic Vision (J-TC 1), the Society of Light and Lighting (SLL in GB) and chair of Technical Committee‚ Discomfort Glare TC 4-33 of the CIE.
