Prof. Sergiy Antonyuk is the Head of the Institute of Particle Process Engineering at the University of Kaiserslautern-Landau (RPTU), Germany. He studied Process Equipment and Engineering at TU Donetsk, Ukraine, and earned his first Ph.D. in Ecological Safety from TU Kyiv in 2004. In 2006, he completed his second Ph.D. in Process Engineering at the University of Magdeburg (Germany) under the supervision of Prof. Jürgen Tomas, continuing his research in Particle Technology as a postdoctoral researcher in the same group. From 2008 to 2014, he served as a Junior Professor for Multiscale Simulation of gas–solid technological processes at TU Hamburg. In 2014, he joined RPTU as a Full Professor of Particle Technology. Since 2024, he has been the spokesperson for the DFG Research Training Group 2908, "Recyclable Wastewater (WERA)," which focuses on recovering the critical raw material phosphorus from wastewater. His research encompasses filtration, aerosol technology, cold spray additive manufacturing, contact mechanics and particle breakage, powder flow behavior, and multiphase flow simulations.
