Research work, on-going projects and future interests

As a Ph.D student I began to study phylogeny and phylogeography of widespread springtail species with molecular markers to describe their relationships and population structure, and to evaluate the use of this organisms as a model to infer phylogeographic pattern. In recent years there has been increasing attention of the scientific community toward the remarkable diversity, evolutionary complexity, and conservation importance of the flora and fauna in the Mediterranean region, with emphasis on the three major peninsular refugia. With the collaboration of Dr Brent C. Emerson from the University of East Anglia (UEA), UK, I investigated the phylogeographic structure of six very common species of Lepidocyrtus (Collembola) in the North-Western Mediterranean basin. The study revealed an astonishing degree of geographic structure, with numerous deeply divergent genetic lineages, originating between 5 and 15 Mya, with no apparent gene flow among populations, even across close geographic distances. Taking a conservative but robust calibration approach, I revealed a remarkably ancient origin for the group, with long-term persistence of individual lineages over fine geographic scale. This study reveals long-term ecological stability within the region, thus raising new questions on the origin of the southern European fauna. In addition to this, our study highlighted the great phylogeographic utility of Collembola as a model group to reconstruct phylogeographic history within temperate forest regions at very fine geographic scales.
During my PhD I obtained a fellowship at the Smithsonian Tropical Research Institute (STRI) where I initiated a project to investigate and quantify the biodiversity of Panamanian springtails, a group for which virtually no prior data existed. This region, very important from an evolutionary point of view, was the key element in the closure of the Central American Seaway, profoundly affecting gene flow between populations of marine and land species. During my research fellowship at STRI, I sampled more than one hundred species, most of them new to science, all across the country. After my PhD I continued my collaboration with Dr Emerson from UEA and Prof. Pietro P. Fanciulli from the University of Siena. With the use of data from publicly available databases and new sequencing data, we quantified the evolutionary diversity and spatial organisation of Collembola, chosen as a representative of the tree canopy and soil mesofauna and, more importantly, as a compelling evidence of a paradox for its tremendous cryptic diversity and very low taxonomical richness.
During my first postdoctoral fellowship, I was part of SelMol, a national project funded by the Italian Ministry of Agriculture. The aim of SELMOL was the improvement of selective strategies in animal husbandry through molecular genetic methodology using high throughput genotyping of SNPs. My main task was the discovery and characterization of copy number variants (CNVs) within the complete genome of Bos taurus. CNVs are described as segments of DNA (>1kb) that are repeated and polymorphic for repeat number. They represent a major source of genetic variation within mammals, and probably within all animals. They occupy about 5–12% of the human genome and greatly influence phenotypic traits and disease susceptibility, such as in HIV infection, autoimmunity and autism. Using the 54K SNP signal intensities of Illumina bovineSNP50 BeadChip, I characterized the level and patterns of copy number variation among bovine animals to assess the CNV landscape over thousands of individuals.
Over the last two years, as a postdoctoral fellow at the “Sapienza”, University of Rome, I have greatly improved my knowledge of next-generation sequencing methodologies, mainly with the use of the Illumina system, quantifying and characterizing (discovering new transcripts and isoforms) the transcriptome (mRNA-seq and miRNA-seq) of a neonatal cancer, the Medulloblastoma, in collaboration with Prof. Gulino's group in “Sapienza”, University of Rome. Additionally, I also initiated a study on the complex dynamic of mRNA-microRNA interaction, through the identification of competing endogenous RNAs (ceRNA), a class of poly-A+ RNAs that should interfere with coding RNAs and microRNAs, regulating the microRNA action on transcripts.
This research experience with state of the art technology have been very important as it has given me the essential background to address cutting edge questions in evolutionary biology such as phylogeography, phylogenetics and molecular evolution at the scale of genomes.
