Sascha Mehlhase is a postdoc at the Niels Bohr Institute in Copenhagen. While his current physics interests focus mainly on silicon detectors, searches for stable massive particles (R-Hadrons) and the W-boson mass measurement, he spends a lot of his spare time on outreach activities (not just including plastic bricks).

A small scale version of the ATLAS detector can be made available as an official LEGO® product, but I need people to vote for it at LEGO Cuusoo. We need 10,000 votes to be considered by LEGO®.
