Ties Behnke is leading scientist at DESY. He works in the field of experimental particle physics. For many years, he has been working in the field of weak interaction physics, including the measurement of Standard Model parameters with heavy quarks and the development of experimental methods and detectors. After experiments at the Tevatron, at the LEP storage ring and work at HERA, he focused on the future project of particle physics – an electron-positron accelerator at highest energies. The International Linear Collider ILC will complement and extend the findings of the LHC and thus provide deep insights into the fundamental nature of the universe. In this field, over the past years, he was head of an international workgroup that proposed a detector for the ILC, the ILD detector. The development of modern and powerful detectors for the ILC is a major challenge which led to many new and innovative technologies, also having an impact on other fields.
