TheIMC2009programconsistedofthreeinvitedtalksfrominternational- perts, four tutorials on fundamental techniques related to the conference topics, nine regular paper sessions, and a short paper / poster session. We received close to 50 submissions from 15 countries world-wide. Based on the ano- mous reviews provided by members of the international Program Committee, the Steering Committee recommended accepting 50% of the contributions as regular papers and another 15% as short papers with poster presentation. To our regret there were a few interesting papers that we had to reject. However, the reviewing results showed a high quality as well as an interesting variety of submissions. We would like to thank all authors for carefully preparing the results of their worksubmitted to IMC 2009,thus enabling an interesting and high-quality c- ferenceprogram.Moreover,wearedeeplygratefultoallmembersoftheProgram and Steering Committees for their e?orts in quickly and thoroughly evaluating the papers. Finally, our special thanks go to the organizers Ulrike Lucke and Daniel Versick for their great work.They handled all the organizationaltasks as well as the communications, the electronic submission, reviewing, and publi- tion procedure in an e?cient and timely manner.
