Ruben Snellings obtained his Ph.D. in Sciences (Geology) at KU Leuven; afterwards he joined the Magnel Laboratory for Concrete Research at UGent as a post-doc and the Laboratory of Construction Materials at EPFL as a Marie Curie IEF Fellow. He specialized in X-ray powder diffraction and electron microscopy analysis of cementitious materials. From 2014 to 2022 he worked at VITO as a researcher in a wide range of mineral residue upcycling projects. Since 2022, he is associate professor of Applied Mineralogy at KU Leuven. His main field of expertise is the development of low-carbon binders incorporating primary and secondary resources. In 2016, he received the RILEM Colonnetti medal.

Simon Mudd obtained his Ph.D. in Environmental Engineering at Vanderbilt University in 2006, and joined the University of Edinburgh as a lecturer in the School of GeoSciences in 2007. He was promoted to Professor of Earth Surface Processes at the University of Edinburgh in 2016. He has studied tectonic geomorphology, basin sedimentation, hydrology, coastal processes, soil science and application of terrestrial cosmogenic nuclides. He was awarded the Arne Richter Award for outstanding young scientists by the European Geosciences Union in 2013, the Gordon Warwick Medal by the British Society for Geomorphology in 2014, and became a fellow of the Royal Society of Edinburgh in 2020.

Andrew Binley was awarded a Ph.D. in Civil Engineering at Aston University in 1986. He then moved to Lancaster University as a post-doc, working on new approaches for assessing uncertainty in hydrological models. In 1989 he was appointed as lecturer in groundwater hydrology, also at Lancaster University. During the 1990s he initiated research into hydrogeophysics, with a primary aim of utilising geophysical methods to constrain conceptual and numerical models of subsurface flow and transport processes. Much of his current research remains focused on this goal. In 2004 he was promoted to Professor of Hydrogeophysics. He has served as Head of Department and as Faculty Associate Dean since this appointment. In 2012 he was recipient of the (SEG/EEGS) Frank Frischknecht Leadership Award for near-surface geophysics. In 2013 he was elected at Fellow of the American Geophysical Union.
