I am Ph.D. student at the Informatics Institute of UFRGS - Federal University of Rio Grande do Sul. I am working under the supervision of Prof. Marinho Barcellos. I have a bachelor degree in Computer Science by UFRGS (2019).

I have dual citizenship: Italian and Brazilian


My research interests are networked systems, mainly focusing on Internet measurements, Internet cartography, and network analytics. In the past, I have worked with Software Defined Networking (SDN) and data-center networks. I am currently investigating the main connectivity characteristics and evolution of the Brazilian IXP ecosystem, focusing on identifying, quantifying, and analyzing the adoption and impact of remote peerings in different IXPs over the country. My plans for future research include investigating ways to evolve the Internet cartography of peering interconnections leveraging the opportunities enabled by IXPs, increasing knowledge about network redundancy and coverage.


  • IPÊ Analytics

    Transforming raw monitoring data to generate valuable information for network management. Theadoption of multiple monitoring techniques increased the availability of raw data. However, stateof the art is still limited in terms of in-depth analysis and inferences about network behavior, giventhe scale and complexity of WANs and the volume/heterogeneity of data. This project investigatesmethods to analyze, in a longitudinal way, datasets that have been collected from the IPE backbone(Brazilian academic network) for many years. A concrete product will be a web-based system thatwill provide inferences from the combination of multiple large datasets available, internal and exter-nal to the organization. The inferences will help improve performance and security of the backbonenetwork operation, traffic engineering and planning

  • Phoenix SDN Survavibility

    SDN separates control and data planes, but independency between forwarding devices and remotecontrollers introduces challenges on survivability that is, how to preserve network functionalityunder failures and attacks. This project conducts research based on five main pillars: (a) a compar-ative study of existing mechanisms and the subsequent creation of a taxonomy of related literaturestrategies; (b) novel algorithms for controller placement; (c) resilience mechanisms for communi-cation between the control and data planes via alternative channels; (d) development of recoverymechanisms to ensure compliance with high-level policies; and (e) incorporation of security mech-anisms to the control plane. These mechanisms are intelligently combined into a novel and robustarchitectural model.
