Wilfried started his involvement with the IT industry in 1974 when becoming employed by Technical University Vienna as a software engineer for real-time data acquisition in the Physics Department.
After taking on different responsibilities in the Computer Center, he became a member of the group set up to establish the Austrian National Research and Education Network, "ACOnet".
This group eventually was relocated to Vienna University (as a dedicated group within Vienna University's Central IT Department), which in 1996 also established the "Vienna Internet eXchange" (VIX).
After coordinating connectivity of the national research community to EARN and BITNET, and to HEPnet (the high-energy physics network), he became involved with the emerging, IP-based, Internet.
In the late 1980s and early 1990s, he was coordinating the Operations Team of "Ebone" and established the Local Internet Registry for ACOnet in 1993. Iin 2001/2002, he became coordinator of WP3 (WP3: Basic Network Services) in a large-scale research project - "6NET" - launched to assess and to prove the relative maturity and applicability of IPv6 for the next generation of the Internet (and to find out about the open issues).
Wilfried was a long-term co-chair of the RIPE Database Working Group (DB-WG), was a member of the initial Executive Board of the RIPE NCC and is a member of the Team of Arbiters to support the RIPE NCC Conflict Arbitration Procedure.
Other past activities include participation in Government Roundtable, GAC, and Law Enforcement Collaboration meetings, and in the DB-WG'S Data Protection Task Force.
Wilfried is a member of the Address Council since the establishment of the Address Supporting Organisation for ICANN. Other ICANN-related activities include membership in RT4 (whois Policy Review Team) and in the NomComs for 2010 and 2011.
Within the Austrian NREN environment, Wilfried is a member of ACOnet's operational security team "ACOnet-CERT" and was involved in the establishment of and serves on the Advisory Council for the Austrian National CERT "CERT.at".
Wilfried’s current and past training activities include teaching various modules in TRANSITS courses, DNS technology and management, and for more than a decade being being a lecturer (master courses) for various aspects of network technology (including logistics and resource management, DNS, LAN technology, encryption and security) at the University of Applied Sciences in Wiener Neustadt.
Private interests include spending as much time as possible with a partner who is also working in the IT Industry, traveling in Latin America and other nice places around the world. Exposure to South America has led to a growing interest in Latin-American Music and learning Spanish and Brazilian-Portuguese.
The remaining spare minutes are spent on digital photography, raising and nursing plants from warmer regions than Central Europe and on inviting friends to sessions of creative cooking.
