Minjia Shi earned his Ph.D. from the Institute of Computer Network Systems, Hefei University of Technology, China, in 2010. From August 2012 to August 2013, he was a visiting researcher with the School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore. From July 2016 to August 2016, he was a visiting researcher with Telecom Paris Tech, Paris, France. Later, he visited the Sobolev Institute of Mathematics in 2020. He has been a Professor at the School of Mathematical Sciences, Anhui University, since 2017. He is the author of more than 100 journal articles and two books. His current research interests include algebraic coding theory and cryptography.Patrick Solé received the Ingénieur and Docteur-Ingénieur degrees both from École Nationale Supérieure des Télécommunications, Paris, France, in 1984 and 1987, respectively, and the habilitation à diriger des recherches from Université de Nice-Sophia Antipolis, Sophia Antipolis, France, in 1993.He has held visiting positions at Syracuse University, Syracuse, NY, from 1987 to 1989, Macquarie University, Sydney, Australia, from 1994 to 1996, and Lille University, Lille, France, from 1999 to 2000. Since 1989, he has been a permanent member of the CNRS and became Directeur de Recherche in 1996. He is currently a member of the CNRS lab I2M, Marseilles, France.His research interests include coding theory (codes over rings, quasi-cyclic codes), interconnection networks (graph spectra, expanders), vector quantization (lattices), and cryptography (boolean functions, secret sharing schemes). He is the author of over 300 journal articles and 3 books.
