Nathalie FAGEL holds a diploma in Geology and Mineralogy of the University of Brussels and a PhD in Geosciences from the University of Lille (France). She is heading a research group AGEs (Clays, sedimentary and environmental geochemistry) at the Geological Department of University of Liège in Belgium. She has got an expertise on clay mineralogy and sedimentary geochemistry (traces and radiogenic isotopes) on marine and continental series. She is also active in applied research dedicated to the characterization and valorization of raw clays, especially with African colleagues in Morocco and Cameroun. She is currently coordinator of a research and development proposal in the valorization of local resources for the design and promotion of new efficient, accessible and eco-responsible building materials in the Sudano-Sahelian Cameroonian area. She is author or co-author of more than 125 peer-reviewed international papers and was promotor of several international research projects.

Noël Djobo is a chemist with focus on building and construction materials. He obtained his Ph.D in Inorganic Chemistry from the University of Yaoundé I. His research interests include the development of innovative low carbon cement-based building materials from locally available mineral resources (earth, clay, volcanic rock, lateritic soil, etc.) for a sustainable built environment. These involves, alternative cements (geopolymer, alkali-activated material, and phosphate binder) and their use in immobilization of toxic wastes, the development of earthen building materials (compressed earth bricks, earth concrete) as well as concrete blocks. The result of these research works has led to 32 research papers and 2 peer-reviewed conference papers with an h-index of 16 and 875 citations according to Scopus. He has recently been listed by Elsevier as the top 5 % most cited scientists in the world for the year 2020. He has received several prestigious fellowships including the TWAS-CSIR Postgraduate Fellowship in 2015 and the Alexander von Humboldt Postdoctoral Fellowship in 2018. Djobo is a member of many scientific societies: German Chemical Society, American Chemical Society and RILEM (The International Union of Laboratories and Experts in Construction Materials, Systems and Structures). He is also an Affiliate member of the African Academy of Science. He serves as reviewer for several high ranking SCI-journals and is member of independent review committee for two international funding agencies. He is also guest editor of the Frontier in Materials Journal Section Structural Materials.
