Senior Lecturer

My Profile at University of Waikato

I am a Senior Lecturer at the University of Waikato 2019–now. In the past, I have worked for different academic institutions: INF/UFRGS in Brazil 2010–2019, PUC-RS University in Brazil 2008–2009, University of Manchester/BT Labs 2003-2004 in the UK, UNISINOS University in Brazil 1993–2008.

My research has addressed a range of challenges as technology evolved, covering the non-functional properties of performance, security and resilience of networked systems and their underlying protocols (see research outputs). My key research interest has been on Internet measurements and network security. I have regularly contributed to the scientific community by serving in multiple committees.

I am fortunate to have supervised many bright students. Contact me if you are interested, but to be sure I am a good fit for you, please first read my recent work.

Why are you receiving connection attempts from this host?

These connections are part of a computer science research project at the University of Waikato, School of Computing & Mathematical Sciences. This research involves making a small number of harmless connection attempts to every publicly accessible computer on the Internet. Similarly to so many other scientific studies, this allows us to methodologically measure the Internet and analyse trends in technology deployment and security.

As part of this specific investigation, every public IP address in the Aotearoa’s cyberspace receives a handful of packets on IANA standard and non-standard ports. These consist of conventional connection attempts followed by RFC-compliant protocol handshakes with responsive hosts. We use only tools that have been used in dozens of other scientific studies worldwide (e.g. ZMap, Masscan, ZGrab2 and LZR). We never attempt to exploit security problems, guess passwords, or change device configurations. Furthermore, we only receive data that is publicly visible to anyone who connects to a particular address and port.

This project was ethically approved by the University and follows the widely accepted best practices for Internet scanning measurements.

Why are we collecting this data?

The data collected through these connections consists only of information that is already publicly visible on the Internet. It helps us, computer scientists, study the deployment and configuration of network protocols and security technologies. We may be able to detect vulnerable systems and responsibly report the problems to the network operators.

This research helps the scientific community accurately study the Internet.

How to opt out of these measurements

The data is sometimes used to detect security problems and to inform operators of vulnerable systems so that they can be fixed. If you opt out of the research, you might not receive these important security notifications.

If you wish to opt out, please use research-abuse@wand.net.nz to let us know. We will promptly exclude your network from the set of measurements.

Teaching Awards

In Brazil, there is typically one graduation ceremony per semester, with students graduating in Computer Science or Computer Engineering programs. Each of these undergraduate programs select, by vote, two professors they considered the best/most influential in their 4-5 years of study. This is a very prestigious distinction, specially when the faculty is in the order of 60-70 professors and lecturers. I have been fortunate enough to be awarded several times in my career, spanning different higher-education institutions.
