I am a Ph.D. student at the Computer Networks Group at the Institute of Informatics of the Federal University of Rio Grande do Sul (UFRGS), Brazil. Currently, I'm a Visiting Graduate Student at CAIDA (Center for Applied Internet Data Analysis) in San Diego, California working under the supervision of Dr. Kimberly C. Claffy (+ Bradley Huffaker, Matthew Luckie). Previously, also on the academic background, I received my M.Sc. (UFRGS/2014) and B.Sc. (UNISC/2010) degrees, both in Computer Science. My Ph.D. advisor is Prof. Marinho Pilla Barcellos. In my research activities the problems that I tackle often involve the intersection of theory and practice with particular emphasis on large-scale networked systems.

I study problems in the Internet interconnections, global Internet routing, information control, and the performance of the networks infrastructure. My previous research experience was with network infrastructure planning and optimization inline within the Software-Defined Networking paradigm and, also with Peer-to-Peer systems focusing on monitoring the Torrent universe to pinpoint sharing of illegal files (e.g. child pornography) and copyrighted content (e.g. movies, software, music, books, games). As an Assistant Professor I taught classes that range from Computer Networks, Management of Computer Networks to Operating Systems and Web Applications Development. Before joining the academia, I was a developer and a team coordinator during 10+ years for the computer industry in Brazil.

Research Projects

Currently, I am mostly working on the following projects:

  • Dynam-IX: Dynamic Interconnection eXchange: Dynam-IX enables IXP members with a high-level interconnection intent abstraction to express their business policies and establish interconnection agreements in short time frames (started: 2016).
  • GT-IPÊ Analytics: Transforming raw monitoring data to generate valuable information for network management: Develop a system to analyze large volumes of network monitoring data and offer inferences to aid network operation, traffic engineering, and planning. Funded by RNP (started: 2017)
  • Uncovering the Hidden Dynamics of Changing Internet Interconnections: investigate the dynamics of network peering infrastructures to better understand how it impacts Internet performance, funded by Microsoft Research (Microsoft Azure Research Award) (started: 2017)

In the past, I had been involved in the following projects:

  • Phoenix: towards a robust and survivable SDN architecture: This research project proposes to investigate and develop an architecture that strengthens current guarantees and coordinates mechanisms to improve survivability, funded by MCTI/CNPq (2014–2016)
  • Towards Better Networking Design and Maintenance: This project aims at developing optimization techniques that can be applied both at network design and during its lifespan in order to improve network performance, funded by Microsoft Research (Microsoft Azure Research Award) (2014–2016)
  • SecFuNet: Security for the Future Networks using trusted components, funded by FP7 and CNPq (2011–2014)
  • SE-UNIT and GT-UNIT: Experimental Service Observing the BitTorrent Universe Through Telescopes, funded by RNP (2010–2013)
