Biographical Sketch

Robert Preissl is a postdoctoral scholar in NERSC's Advanced Technologies Group and works closely with physicists at the Princeton Plasma Physics Laboratory to optimize and analyze parallel magnetic fusion simulations.

Originally from Austria, Preissl earned a doctorate degree in computer science from Johannes Kepler University in Linz. While pursuing his doctorate, Preissl contributed to research on automated source-to-source transformation and program analysis of MPI parallel applications as a research intern at the Lawrence Livermore National Laboratory. Prior to that internship, he worked on performance analysis tools for JAVA multithreaded applications at the IBM Haifa Research Laboratory in Israel, and ported physics applications to virtual machines by using the Berkeley Open Infrastructure for Network Computing (BOINC) at CERN in Switzerland.

In his spare time, Preissl enjoys spending time outdoors cycling, playing soccer, running and hiking.
