Associate Professor at the University of Cantabria

Carlos Thomas has been an Associate Professor at the University of Cantabria since May 2023. He holds a University Expert degree in Structures and Building Pathology, a PhD in Civil Engineering Models from the University of Cantabria, and a Bachelor’s degree in Science, specializing in Fundamental Physics.
His professional experience combines research, teaching, and industry collaboration. He has served as Assistant Professor, Contracted Doctor, and Coordinator of Industry Relations and Research at the School of Civil Engineering (ETS) at the University of Cantabria. Previously, he worked as a professor at the Gimbernat-Cantabria University Schools and as a contracted researcher at the University of Cantabria. He has also held technical and research roles in the private sector with companies such as CarbonTek SL, Mercedes-Benz, DaimlerChrysler, and Bosch-Siemens.
His scientific activity focuses on the development and evaluation of sustainable construction materials, with special emphasis on the use of recycled aggregates in structural concretes. He has led and participated in multiple publicly and privately funded projects, always centered on the valorization of construction and demolition waste. He is the author of over 60 scientific publications and has been a speaker at leading conferences.
He stands out for the quality and impact of his scientific output: one of his articles was recognized four times among the 25 most downloaded on ScienceDirect, and he has two Highly Cited Papers in the Clarivate 2021 ranking. He has conducted research stays in France, Germany, Brazil, and Portugal within programs such as Socrates-Erasmus, Leonardo, and José Castillejo.
In the editorial field, he is Editor-in-Chief of the Journal of Building Engineering (Q1, Elsevier) and a member of the editorial boards of Applied Sciences and Heliyon. He has been a guest editor of several special issues on eco-efficient concrete and structural repair materials. Additionally, he is co-editor of the books Waste and By-Products in Cement-based Materials, The Structural Integrity of Recycled Aggregate Concrete Produced with Fillers and Pozzolans, and Construction and Building Repair Materials.
He currently chairs the Scientific Committee of the ACHE International Structures Congress and maintains an active role in technology transfer and outreach in the field of materials engineering.
