Ivor Fleck was born in Hannover, Germany. He has studied physics at the Universities of Hannover and Munich and did his PhD at the University of Hamburg with the first data from the ZEUS experiment at DESY. He worked as a postdoc at the Universities of Glasgow and Tokyo and was a fellow at CERN before he went to Freiburg University, where he did his Habilitation. In 2005 he became Professor of Physics at the University of Siegen, Germany. He spent sabbaticals at the University of Cambridge and the University of Tokyo. Since 2015 he is Dean for Research of the School of Science and Technology at the University of Siegen and is Founding Chairman of the Center for Particle Physics Siegen.  He has worked at many of the large facilities for particle physics, namely DESY, CERN, KEK and Fermilab. His research fields are experimental particle physics and detector development. His analysis topics range from structure functions at ZEUS to search for Supersymmetry at OPAL andtop quark properties at D0 and ATLAS. He also works on developing detector components for the ILD detector at the International Linear Collider (ILC) and the International Axion Observatory (IAXO).  Maxim Titov was born in Kyiv, Ukraine on May 6, 1973. He received his Master Degree from the Moscow Institute of Physics and Technology and defended his PhD in 2001 in the Institute of Experimental and Theoretical Physics, Moscow, Russia. He completed his Habilitation as a Director of Research (HDR) in 2013 from University Pierre and Marie Curie (Paris VI), France. Currently, he is a Senior Scientist at CEA Saclay, Irfu, France. A nuclear and particle physics researcher for his entire carrier, Prof Titov has been involved in the development of novel detector technologies and analysis of physics data at collider experiments, inevitably within large international collaborations: HERA-B Experiment at DESY, Hamburg; D0 Experiment at FERMILAB, Chicago; ATLAS and CMS Experiments and RD51 Collaboration at CERN, Geneva; and International Linear Collider (ILC) He was Founding Member and served as the Spokesperson of the RD51 Collaboration at CERN (2007-2015). Nowadays, he is Member of CMS, RD51 and Particle Data Group (PDG) Collaborations and involved into science-policy preparation of the ILC project in Japan Claus Grupen Universität Siegen, Siegen, Germany Irène Buvat Unité Imagerie Moléculaire In Vivo, Orsay, France
