Work interests

My research interests focus on the macroevolution of chondrichthyans (cartilaginous fishes including sharks and rays) on the basis of their fossil remains. Part of my research relates to the study of Meso-Cenozoic chondrichthyan faunas with special emphasis on palaeoenvironmental and palaeogeographic constraints triggering the distribution and evolution of their diversity. Another part of my research focuses on tooth histology (enameloid microstructure) and its phylogenetic and adaptive signal among chondrichthyans. To a greater extent, I am interested in the understanding of macroevolutionary patterns of various “fish” groups (chondrichthyans and osteichthyans) and other marine vertebrates. This is based on the analysis of the fossil record with the aim of understanding the biotic and abiotic factors underpinning the evolutionary history of these groups over the past 250 million years.
My teaching activities include palaeontology, evolution and geology at all levels from 1st year B.Sc. to M.Sc.
