My interests include a variety of subjects, such as

  • quantum field theory, in particular lattice QCD
  • random matrix theory
  • mathematical physics
  • high-performance computing
  • supercomputer design and development

I'm the principal investigator of a project in the framework of the SFB/TR-55 in which we develop custom-designed supercomputers for QCD and similar applications. In the first funding period we developed the QPACE Computer in collaboration with IBM and other companies (Eurotech, Xilinx, Knürr) and academic institutions (DESY Zeuthen, Research Center Jülich, Wuppertal Univ., Milano Univ., Ferrara Univ.). The architecture of QPACE is based on the PowerXCell 8i processor and a reconfigurable network coprocessor implemented on an FPGA. QPACE was the most energy-efficient supercomputer in the world in 2009/2010 (No. 1 on the Green 500 list) and is currently used for the physics program of the SFB/TR-55. In the second funding period (starting in 2013) we will develop QPACE II, this time on the basis of Intel's MIC technology.

If you are interested in doing a master or doctoral thesis on one of these subjects, just contact me.
