He is the editor-in-chief of the Journal of Building Engineering, an associate editor of the European Journal of Environmental and Civil Engineering, a member of the editorial boards of 15 other international journals and a member of the CIB, FIB, RILEM, IABMAS and IABSE organisations. Carlos Thomas is an Associate Professor at the Materials Science and Engineering Laboratory in the Civil Engineering School of the University of Cantabria, Spain. He received his International PhD with cum Laude and Extraordinary Doctorate Award in 2013. His research activity has focused on the evaluation of construction, demolition and industry wastes for the manufacture of recycled mortars and concrete. In the last five years, he has participated as Principal Investigator in 5 R&D projects and as a researcher in another 10 R&D projects, with both public and private funding, related to recycled materials. He is the author of 20 JCR papers, one of them certified as one of the 25 most downloaded in ScienceDirect, and more than 80 congress communications and conferences. He has undertaken research stays in France, Germany, Brazil, and Portugal, and he is one of the promoters of the "Spanish Recycled Concrete Network". César Medina is a Full Professor of Civil Engineering at the University of Extremadura, Spain. He received his Doctorate in 2011 from the University of León.
