Loïc Chaumont was educated at Université du Maine (Le Mans) and Université Paris 6 and is currently a professor of mathematics at Université d'Angers. He published over 50 research papers on theory of stochastic processes, both in discrete and continuous times. His main domain of research concerns Lévy processes. He was the director of LAREMA, the CNRS mathematics research unit in Angers, from 2012 to 2016. Andreas E. Kyprianou was educated at the University of Oxford and University of Sheffield and is currently a professor of mathematics at the University of Bath. He has spent over 25 years working on the theory and application of path-discontinuous stochastic processes and has over 130 publications, including two graduate textbooks on Lévy processes. During his time in Bath he co-founded and directed the Prob-L@B (Probability Laboratory at Bath), was PI for a multi-million pound EPSRC Centre for Doctoral Training and is currently the Director of the Bath Institute for Mathematical Innovation.
