Marinho Barcellos is a Senior Lecturer at the School of Computing and Mathematical Sciences at the University of Waikato, NZ. His research focuses on Internet measurements and network security, some of which include IXPs as vantage points. More broadly, his research has addressed various challenges as network technology evolved, covering the non-functional properties of performance, security and resilience of networked systems and their underlying protocols.

Marinho Barcellos has regularly contributed to the network research community by serving in multiple committees, including the general co-chair of ACM SIGCOMM 2016 and the Program Committee co-chair of ACM CoNEXT 2022. He has been on several TPCs of conferences, including ACM CoNEXT, ACM IMC, IEEE INFOCOM, IEEE ICNP, ACM HotNets, and IFIP Networking. He was a member of the ACM SIGCOMM Executive Committee 2017-2021, and is currently a co-chair of the ACM SIGCOMM CARES committee. In addition, he was a member of the steering committees of ACM CoNEXT and the PAM Conference, and currently chairs the Advisory Board of the ACM PACM-NET journal.

Marinho Barcellos received his PhD from the University of Newcastle upon Tyne, UK, in 1998. While in Brazil, he was a PI of multiple research projects on network security (e.g. P4Sec) and Internet measurements. Before moving to NZ, he worked as an Associate/Adjunct Professor at UFRGS University (2010–2019), UNISINOS University (1993–2008), PUC-RS University (2008–2009), as well as an Invited Adjunct Professor at UNAL, Colombia. In 2003-2004, Marinho worked for the University of Manchester in a joint project with BT Research Labs (2003-2004) for multicasting large volumes of scientific data.
