Dr. József Nagy graduated from the Vienna University of Technology in Physics and finished his PhD in Chemical Engineering. For six years he held the position of a post-doc at the Johannes Kepler University, where he worked on polymer materials. He is the Chair of the Technical Committee for Tutorials and Documentation in the OpenFOAM Governance System. He has the biggest YouTube channel with specialized tutorials for learning CFD with OpenFOAM. Currently he is a CFD engineer at eulerian-solutions. His areas of interest are diverse, multiphase flows, complex materials, porous media, fire and species dispersion, Fluid-Solid Interaction (FSI) and model development and implementation as well as custom workflows for specific applications.

Dr. Eugene de Villiers is the Managing Director of Engys Ltd, a leading provider of open-source CFD for the enterprise sector and developer of the OPENFOAM-based HELYX suite. He received his Ph.D. from Imperial College London, where he worked in the group of Prof. David Gosman, one of the pioneers of commercial CFD and the co-founder of CD-Adapco. This was the same group that created FOAM - renamed OPENFOAM. He has made significant contributions to the code, particularly in the context of the grid generator now known as "snappyHexMesh". Currently, he leads a team of talented young developers working on a diverse set of topics, including (but not limited to!) multi-phase, immersed boundaries, advanced solver algorithms, adjoint optimisation, CHT, turbulence modelling, machine learning and mesh generation.

Mark Olesen moved to Germany after the PhD and worked for several years in the automotive industry (internal flows) with various commercial tools, in addition to integrating OpenFOAM into the development process. During this period (OpenFOAM-1.3 and later), multiple contributions were fed back into the OpenFOAM code base. Mark joined OpenCFD Ltd. as a core developer in 2016.
