Matthieu Le Tacon (born 1980) studied physics in Orsay and obtained his PhD in 2007 from the University Paris Diderot. After a short postdoctoral stay at the Laboratoire de Physique des Solides in Orsay, he joined the ESRF to work on the inelastic x-ray scattering beamline ID28. In 2009, he was appointed head of the Inelastic Photon Scattering group in the Solid-State Spectroscopy Department of Prof. B. Keimer at the Max Planck Institute for Solid State Research. In 2016, he became Professor of Experimental Physics at KIT and Director of the Institute of Solid-State Physics, which was restructured in 2020 to become the Institute for Quantum Materials and Technologies.
