Werner Backes received his Computer Science degree in February 2000 in Germany at the University in Saarbruecken; he was working on Lattice Basis Reduction and the Shortest Vector Problem. Backes received an offer to do his PhD at the Max-Planck Institute for Computer Science in Saarbruecken. He worked on Abstract Interpretation of Intermediate Codes and developed the tool xGCC for the analysis of XRTL. After his PhD (January 2005), Backes started to work again on Lattice Basis Reduction at Stevens Institute of Technology with Prof. Wetzel. He still works on the xGCC tool whenever he has the time. It's a kind of hobby.
