About Me

After graduating from the University of Freiburg, Germany, I joined NICTA and Griffith University, Australia, in the beginning of 2007 as a PhD candidate. My PhD advisors are Dr. Charles Gretton, Dr. Malte Helmert, and NICTA group leader Prof. Abdul Sattar. My main research interests are in AI planning and search.

    Note: After publication, we found a bug in our implementation that affected the results in the columns "CG heuristic/local" and "blind heuristic/local" of Table 1. The version of the paper available for download here corrects these errors.
