Klaas Wierenga

Klaas Wierenga invented eduroam, which provides free, secure, international wi-fi roaming service to academic and research communities when they travel to participating institutions all over the world. 

Available in over 100 countries on every continent, eduroam has helped increase collaborative initiatives among universities and schools. 

Wierenga started eduroam in 2002 while at SURFnet, the Netherlands’ National Research and Education Network (NREN), where he also built the first generation of federated identity systems

Following a successful pilot, eduroam was adopted by GÉANT, the pan-European research and education network, as an international roaming service for academics and researchers.

Built on the most secure encryption and authentication standards in existence today, eduroam has empowered institutions to provide global access without globally-centralized identity management. 

Wierenga, who currently serves as chief community support officer at GÉANT, is the co-author of Building the Mobile Internet (Cisco Press, 2011) and Wireless Networking in the Developing World (2013), as well as three Requests for Comment (RFCs). He also holds five U.S. patents.
