I'm an IT professional and currently do researcher for the US government. I have been strongly interested in free softwares since I got into IT and use almost exclusively free softwares. My main areas of expertise are java and C#, and I love the gnome desktop. I also know a bit about video games, simulation and ontologies since those were subjects of my research projects. If you want to know more about the lasts things I have been working on, have a look at my blog at http://guillaumeradde.blogspot.com/ .
