Giovanni completed his pre-university education in Bologna, Italy, before undertaking his undergraduate and Master’s degrees in Biology at the University of Oxford (2018-2022). His Master's thesis focused on the early evolution of chordates - the animal group comprising vertebrates and their closest relatives. He tackled this problem by integrating evolutionary and developmental evidence with the palaeontological record, describing new specimens of the enigmatic Cambrian fossils known as "vetulicolians" and leading a redescription of the iconic Cambrian chordate Pikaia. During his undergraduate degree, he also took part in research on the early Triassic fossil record of south-western England, reconstructing an insular ecosystem from the early beginnings of the age of dinosaurs.
Giovanni's doctoral research is continuing to map the Cambrian origins of major animal bodyplans. He is describing new fossil faunas from poorly known Cambrian environments, such as periodically desiccating lagoonal environments and highly productive shallow marine settings, through the lens of "Small Carbonaceous Fossils": organically preserved fossils too small to be visible on bedding planes, but too large and delicate to be recovered through standard palynological techniques. In addition, Giovanni is continuing his investigation on chordate origins by studying new fossil vetulicolians that clarify the origins of key vertebrate adaptations.
