Jens Harting
Helmholtz Institute Erlangen-Nürnberg (HI ERN), Germany
Prof. Dr. Jens Harting is Head of the Research Department Dynamics of Complex Fluids and Interfaces at the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy (HI ERN), where he leads advanced research on simulation and modeling techniques for complex fluid systems and thin-film manufacturing technologies. His research focuses on the development of computational and theoretical approaches for printing and coating processes aimed at optimizing the production of high-performance solar cells and electrocatalytically active thin films. His work combines fluid dynamics, soft matter physics, statistical mechanics, and materials science to address fundamental and applied challenges in renewable energy technologies. Prof. Jens Harting has made significant contributions to the modeling and simulation of structure formation processes occurring during printing, drying, and post-processing stages. His research encompasses wetting and spreading phenomena of liquids, dispersions, and emulsions through thin-film equations and mesoscale simulation methods, as well as the rheological behavior of highly filled dispersions. A major aspect of his work involves the application of statistical mechanics to understand the dynamic evolution of interactions between molecules and nanoparticles, which govern aggregation, self-organization, and the rheological properties of complex thin films. His investigations also include coupled heat and mass transfer processes during deposition and drying, with particular emphasis on defect generation and crack formation mechanisms. In addition, Prof. Jens Harting studies the influence of post-processing treatments on defect states under various environmental conditions, contributing to the development of more reliable and efficient functional materials for energy applications. Through his interdisciplinary research activities, Prof. Harting has established himself as a leading scientist in the fields of complex fluids, thin-film physics, and computational materials engineering, fostering innovative solutions for next-generation renewable energy technologies.

Paulo Cesar Philippi
Pontifical Catholic University of Paraná (PUCPR), Brazil
Prof. Paulo Cesar Philippi is a distinguished Brazilian researcher in the fields of Thermofluid Sciences, Computational Fluid Dynamics, and Kinetic Methods. He earned his degree in Mechanical Engineering from the Federal University of Santa Catarina in 1973, followed by a Master’s degree in Aerospace Engineering and Technology from the National Institute for Space Research in 1975, and a Ph.D. in Fluid Thermophysics from the University of Provence in 1980. From 1975 to 2016, he served as faculty member at the Department of Mechanical Engineering of the Federal University of Santa Catarina, becoming Full Professor in 1993. He currently holds the position of Full Professor at the Pontifical Catholic University of Paraná. Prof. Paulo Cesar Philippi has played a pioneering role in the development of advanced courses in Thermodynamics, Porous Media, and Kinetic Methods in Fluid Mechanics at both undergraduate and graduate levels. His research activities are centered on multidisciplinary problems at the frontier of science, requiring rigorous physical modeling and mathematical formulation. Since 1997, he has been actively engaged in the theoretical development of discrete forms of the Boltzmann equation and advanced lattice Boltzmann methods. He has authored or co-authored more than 200 peer-reviewed journal and conference publications and supervised approximately 80 graduate and undergraduate research works, including Ph.D. theses and Master’s dissertations. Prof. Paulo Cesar Philippi is also a member of the International Scientific Committee of the annual Discrete Simulation of Fluid Dynamics Conference (DSFD), recognized worldwide as one of the leading forums for researchers working on cutting-edge developments in discrete and kinetic approaches to fluid dynamics. His current research project focuses on phase transition phenomena and immiscible displacement processes in microcavities and porous media. This long-term research line, developed over nearly three decades, involves the numerical simulation of complex multiphase flows through the development of high-order lattice Boltzmann models, addressing discretization challenges and fluid-fluid and fluid-solid interaction mechanisms in microgeometries.
