Core Team

The core team of the OpenINTEL project consists of the following people (in alphabetical order):

Anna Sperotto
Anna procures research funding for PhD and postdoctoral research projects that use OpenINTEL data. She supervises PhD students that work with OpenINTEL data for their research.
Mattijs Jonker
Mattijs manages the development on the Big Data side of OpenINTEL, which ranges from having designed the data schema, to building data pipelines to collaborating institutions. He also administers the OpenINTEL Hadoop cluster, oversees day-to-day operation with the rest of the team, and tutors colleagues and collaborators in data use and analyses.

Olivier van der Toorn
Olivier takes care of the monitoring of the OpenINTEL measurement infrastructure, when a measurement stalls he is the first to know. Additionally, Olivier is closely involved in maintaining this infrastructure.

Roland van Rijswijk-Deij
Roland designed the architecture of OpenINTEL, writes most of the core measurement code of OpenINTEL and takes care of continuously expanding the measurement with new TLD data sources. Next to this, he manages the funding of the OpenINTEL measurement cluster and Hadoop cluster.

Key Contributors

We thank the following people for their key contributions to the OpenINTEL project:

Alberto Dainotti
Alberto is a senior research scientist at the Center for Applied Internet Data Analysis (CAIDA) at the University of California San Diego. He initiated the collaboration between the OpenINTEL project and CAIDA and is responsible for the MADDVIPR project on the US side of the collaboration.

Alistair King
Alistair works at the Center for Applied Internet Data Analysis (CAIDA) at the University of California, San Diego. Alistair contributes to improving the operations of the OpenINTEL measurement cluster, and provides insight on new analysis methods for OpenINTEL data, other than Hadoop. Alistair also helps ensure OpenINTEL is safely replicated at CAIDA.

Cristian Hesselman
Cristian directs SIDN Labs, the research team of the .nl registry, SIDN. He helps fund the OpenINTEL Hadoop cluster and acts as an ambassador for the project, for instance towards other ccTLD operators. In addition to this, Cristian is the one who originally came up with the name 'OpenINTEL'.

Jeroen van Ingen-Schenau
Jeroen works in the Library, ICT Services and Archive (LISA) department at the University of Twente where he is a network specialist. Jeroen ensures that OpenINTEL has the network resources it needs to perform measurements and analysis on the Hadoop cluster.

Maarten Wullink
Maarten is a member of the SIDN Labs research team at SIDN, the registry for .nl. OpenINTEL benefited from Maarten's extensive expertise in operating Hadoop clusters. He helped write the hardware specifications for our cluster nodes as well as with the installation of the cluster and getting us started using it.

Paul Dekkers
Paul works for SURFnet, the National Research and Education Network in The Netherlands, where he is part of the Networking Department. Paul helps with his OpenStack expertise and has installed and configured the OpenINTEL measurement cluster.
