Hi there!
I'm Thomas and I am a student of medical Biology at the Radboud University in Nijmegen, the Netherlands. My basic activity here on Wikipedia is to add further information to topics I get to do with during my study. You can figure out that this is a very sporadic activity. Sometimes I check articles on Wikipedia to get some more information on certain topics and find out that I actually know a bit more than what is here already, so I add that bit. It doesn't happen often, but I still like the idea to contribute to common knowledge :-)
Cheers, Thomas
