Trond Saue, born 1964 in Norway, is a CNRS senior scientist (DR1). After obtaining a PhD in theoretical chemistry at the university of Oslo in 1996, he did postdocs at the University of Odense (Denmark) and Université Toulouse III -  Paul Sabatier (France) and worked as associate professor at the University of Tromsø (Norway) before joining CNRS in 2001. He first worked at the  Laboratoire de chimie quantique in Strasbourg before moving to Toulouse in 2010 to join the Laboratoire de Chimie et Physique Quantiques. He is an expert in relativistic quantum chemistry and initiated the [[http://www.diracprogram.org/doku.php|DIRAC]] program for relativistic molecular calculations, of which he today is one of five main authors. Since 2011 he is director of the [[http://www.esqc.org/|European Summerschool in Quantum Chemistry (ESQC)]]. In 2016 he was elected member of the [[https://www.iaqms.org/index.php|International Academy of Quantum Molecular Science]].

Johann Pototschnig, born 1987 in Austria, obtained his PhD (entitled //A theoretical study of metal containing diatomic molecules: Quantum chemical studies on selected systems featuring electric and magnetic dipole moments//) in technical physics at the Graz University of Technology in 2016, under the supervision of [[https://www.tugraz.at/institute/iep/institut/homepage-mitarbeiter/prof-ernst/|Wolfgang E. Ernst]] and [[https://www.staff.tugraz.at/andreas.hauser/index.html|Andreas W. Hauser]]. He then did postdocs at the Max Planck Institut für Kohlenforschung in Mülheim (2018) and at the Vrije Universiteit Amsterdam (2019-2020). His main task in the HAMP-vQED project will be to work on the two-electron interaction, going beyond the instantaneous Coulomb two-electron interaction.

Maen Salman, born 1994 in Lebanon, obtained a bachelor degree in Physics at the Lebanese University in 2015. He next obtained a Master degree at the Aix-Marseille university in 2018 and then his PhD (entitled //Quantum Electrodynamic Corrections in Quantum Chemistry//) at the Toulouse III - Paul Sabatier University in 2022. His main task in the HAMP-vQED project will be to work on a variational formulation of QED, including regularisation and renormalization in coordinate space.

Gabriele Fabbro, born 1998 in Pordenone, Italy, obtained a bachelor degree in chemistry at the University of Trieste in 2020 and is currently pursuing a Master of theoretical chemistry at the same institution. 
His internship, associated with HAMP-vQED project, was to work on analysis and accurate calculations of the electric field gradient at nuclear position, used in combination with experiment to extract nuclear electric quadrupole moments, but also providing information about chemical bonding. Starting Nov 2022, he has embarked on a PhD-thesis on closed-shell coupled cluster response theory.

Ryan Benazzouk, born 1999 in Paris, is currently pursuing a double diploma between [[https://www.isae-supaero.fr/en/|ISAE-Supaero]], studying engineering, and Université Paul Sabatier, studying theoretical physics. His internship, associated with HAMP-vQED project, was to study vacuum polarization within a finite basis approximation. During his thesis he will attack the much harder problem of regularization and renormalization in the finite bases of quantum chemistry.
