Welcome to the Internet presence of Jeroen Massar.
This website contains all kinds of tidbits that you might not want to know about me.
For the folks who don't know me from work, and thus ask what I do for a living, I'll typically answer "I play with the Internet".
A better summary could be "I design and build secure privacy centric tools for improving Internet communication between people and machines". The in-depth explanation can be discovered by browsing my publications, presentations and project pages because, there is quite a lot more to it. I am a helper and try to improve the state of the world, especially in communications.
Next to internet related hobbies like working on Mesyx and Massar's Network I also love seeing the world above by hike or bike and the world below with scuba.
