Curriculum vitae
Riccardo received his bachelor’s degree in biology at University of Cagliari in 2016, with a thesis entitled “Colocalization of alpha-2A adrenegic receptors in the ventral tegmental area”, supervised by Prof. Saturnino Spiga. The thesis was focused on the putative noradrenergic control on the mesolimbic system in the rat brain. In particular, he took part to the neuroanatomical surveys, working on the 3D confocal reconstructions.
He earned his master’s degree in marine Bio-ecology with the highest honours from the University of Cagliari in 2018. Prof. Saturnino Spiga supervised the thesis titled “Effects of Caulerpa cylindracea (Sonder, 1845) withdrawal in diencephalic neurons of Diplodus sargus (Linneus, 1758) brain.” This thesis study was inspired by the well-known behaviour of the omnivorous fish D. sargus, which can become a selective feeder of the algae C. cylindracea, an invasive species of the Mediterranean Sea that has a negative impact on the D. sargus. Notably, the study focused on the neuroanatomical effects of C. cylindracea withdrawal on a specific group of dopaminergic neurons implicated in the fish’s reward system, explaining a part of the mechanisms involved in this food seeking and intake. Riccardo did not limit himself to marine biology for the duration of his internship. He gained experience in histology procedures by interning in the old neuroanatomy laboratory, which ranged from the smallest fish brains to the largest human brains, taking part in a collaboration between University of Cagliari and USA research group (NeuroDigiTech).
After the graduation, he presented his thesis work at the project’s concluding conference, “Impact of invasive alien species on Sardinian ecosystems,” in which his supervisor was a co-author.
In 2019 won a research scholarship for the project “New methods for visualization and characterization of human neurons (post-mortem)”, supervised by Prof. Saturnino Spiga. This project focused on using long-preserved human brain tissue in formalin to combine the Golgi staining and immunofluorescence, making these tissues accessible for the study of human brain diseases. The obtained results were presented during the conference “Italian Group for the Study of Neuromorphology (2020)”. The presented scientific contribution was awarded with a price for one of the best young researcher’s lines.
Since 2022, he has been a collaborator for the Italian “National Inter-university Consortium for Marine Sciences”, participating to the collecting of meristic data in research fishing campaigns in the seas surrounding Sardinia (GSA 11), linked to the MEDITS european program.
Nowadays, Riccardo is a PhD student at Cagliari University, under the supervision of Prof. Maria Cristina Follesa and Prof. Saturnino Spiga. His current research focuses on the neuroecology of cartilaginous fish, with particular interest on the brain pituitary gonadal system, with the main aim of characterizing the anatomical changes in the reproductive cycles.
