Christophe Grojean

Theoretical particle physics

Christophe Grojean is Lead Scientist in the DESY Theory group and Professor of Theoretical Physics at Humboldt University in Berlin. Throughout his career, he has addressed numerous topics in particle physics beyond the Standard Model. He is an expert in the physics and dynamics of the Higgs boson and its possible manifestations depending on the underlying theory. To establish the profile of the Higgs boson, he works closely with experimentalists. He is also involved in various working groups dealing with the physics case for the next colliders after the Large Hadron Collider (LHC).

Christophe Grojean started his research work in theoretical high-energy physics at the French research organisation CEA in Saclay and got his PhD from Orsay University in 1999. After two years at the University of California in Berkeley, he returned to Saclay, followed by a visiting professorship at the University of Michigan in Ann Arbor and a seven-year employment at CERN. In 2012, he joined the Institut de Física d’Altes Energies at Universitat Autònoma de Barcelona as an ICREA Research Professor, before relocating to DESY and Humboldt University in Berlin in 2015
