Thomas Wriedt studied Electrical Engineering in Kiel and Bremen, Germany. He received his Dr.-Ing. degree in Microwave Engineering from the University of Bremen in 1986. From 1986 to 1989 he was a postdoc researcher at the University of Bremen's Department of Process Engineering, working on optical particle characterization. He has been the head of the Powder and Particle Measurement research group at the Stiftung Institut für Werkstofftechnik (IWT) (from January 2018: Leibniz-Institut für Werkstofforientierte Technologien (IWT) ), Bremen since 1989. His current research focuses on the Null-field method with Discrete Sources (NFM-DS) for simulation in optical particle characterization and generally light scattering by particles. He has authored and co-authored four books and 170 peer-reviewed papers.Yuri A. Eremin graduated from the Physics Faculty of Lomonosov Moscow State University (MSU), Russia in 1972. He received his Ph.D. in Mathematical and Theoretical Physics from Lomonosov Moscow State University (MSU) in 1976. From 1975 to 1982 he was a research scientist at the Research Computing Center (RCC) of MSU. From 1982 to 1992 he was a senior researcher at the Computational Mathematics and Cybernetics Faculty of MSU. He obtained his Dr. Sci. degree in Mathematical Modeling from MSU in 1989. Since 1993 he has been the head of a research group at the Computational Mathematics and Cybernetics Faculty of MSU. His current interests are direct and inverse light scattering problems. He is the author of the Discrete Sources Method that enables the construction of effective computational models to simulate light scattering. He has authored more than 215 papers in scientific journals and four books.
