About myself

Born 1979 in Aachen, I studied Computer Science at RWTH Aachen University and obtained in 2007 the degree of Diplom-Informatiker. Since 2007 I pursue Ph.D. studies at the RWTH Aachen University at the Institute for Scientific Computing under the guidance of Prof. Christian Bischof and Prof. Martin Bücker. In Juli 2011 I went to the TU Darmstadt, together with Prof. Bischof.
