Biographie


V. Mauchamp is Professor at the department of Physics of the University of Poitiers. After a master’s degree in Condensed Matter Physics from the Univeristy Paul Sabatier (Toulouse, Fr), he received a Ph.D degree in materials science from the University of Nantes where he worked on the characterization of lithium-ion battery electrodes using Electron Energy-Loss Spectroscopy. After a post-doc at the INSA Lyon, he joined the Pprime institute in 2007 as an associate professor working on the electronic properties of MAX phases. He became Professor in 2019 and is now mainly interested in the electronic structure and electronic properties of 2D-dimensional transition metal carbides (so-called MXenes) as probed by different kinds of electron spectroscopies associated to Density Functional Theory simulations. He is head of the team ‘Physics and Properties of Nanostructures’ at the Pprime institute.
