He was also Invited Researcher at the University of Montpellier (France) in 2016-2017.

His research interests are i) the chemostratigraphy of vertebrate-bearing sediments, and ii) the characterization of supergene ore deposits. This latter includes the petrography, mineralogy and geochemistry of ores associated to weathering processes, around the world. He is author of co-author of more than 130 papers, one book, 13 chapters of books, and more than 230 communications in congress. He was Laureate of the Suzanne Leclercq price (2009) and Laureate of the Price “Geology” in 2004 - Royal Academies for Sciences and the Arts of Belgium.
