Emmanuel Tsesmelis

Professor Emmanuel Tsesmelis Senior Physicist, Directorate Office, CERN Visiting Professor, Department of Physics, University of Oxford Emmanuel Tsesmelis is an experimental particle physicist with a career spanning scientific research, academic teaching, science communication, international relations and management at CERN and at several universities. He is a Senior Physicist in CERN’s Directorate Office and a Visiting Professor in Particle and Accelerator Physics at the University of Oxford. He is an elected Fellow of the Australian Institute of Physics and a supernumerary member of Jesus College, Oxford. He is fluent in English, French, German and Greek. He undertook his studies in Athens, Melbourne and Dortmund. He completed his Ph.D. studies in experimental particle physics at the University of Dortmund, where he worked on the search for the charged Higgs boson at experiments at CERN. From 1993 to 1998, he worked on neutrino experiments at CERN searching for quantum mechanical oscillations of one flavour of neutrino to another. In 1998 he joined the CMS Collaboration at CERN’s Large Hadron Collider (LHC), one of the two experiments that in 2012 announced the discovery of the Higgs boson, and for the period 2005-2008 he was Head of the LHC Experimental Areas. As a result of his research, he has co-authored a large number of scientific papers in refereed journals together with international collaborators. Emmanuel Tsesmelis heads the CERN Directorate Office, which plays a key advisory and support role for the Director-General and Senior Management, providing a source of policy and strategy counsel. As of 2004, he has also been providing strategic advice to CERN Directors-General on international relations of the Organization. In this capacity, he has been responsible for bringing into collaboration with CERN scientists from countries that are in the process of developing their particle physics communities. He also lectures in physics and organizes public engagement events in science, technology and innovation, most notably related to CERN’s Non-Member State Summer Student Programme and High School Teacher Programme and also in relation to the Royal Society’s Summer Science Exhibition in London.
