Christian Maire is a Professor of Mathematics at the University of Franche-Comté since 2007, based at the FEMTO-ST Institute. Previously, he held positions at Toulouse II University and Bordeaux I. His expertise lies in Number Theory, Algebraic Number Theory, and related fields, with a focus on Galois representations, pro-p extensions, and arithmetic geometry. He has been actively involved in international collaborations, including projects in Africa, such as the 'Arithmetic and Geometry in Central Africa' initiative, and has supervised numerous doctoral students across multiple countries. Education and Academic Background Ph.D. in Mathematics, University of Besançon, 1995 (under supervision of Georges Gras) Accreditation to Supervise Research (HDR), University of Bordeaux I, 2001 Research Interests Maire’s research focuses on algebraic number theory, including pro-p extensions, class field towers, ramification theory, and Galois module structures. He has contributed to understanding the structure of number fields and their extensions, with applications in cryptography and coding theory. His work often involves collaborations with researchers worldwide, particularly in developing countries, promoting mathematical education and research in Africa. Grants and International Collaborations Maire has coordinated and participated in multiple international projects, including: Co-coordinator of the 'Arithmetic and Geometry in Central Africa' project Visiting positions at Cornell University, University of Massachusetts, and Harbin Institute of Technology Organizer of events like the African Mathematics School in Brazzaville and the Gabonese Workshops in Arithmetic Doctoral Supervision He has supervised over a dozen PhD students, including co-supervision agreements with institutions in Gabon, Congo, Burkina Faso, and Mongolia. Notable current collaborations include the supervision of Copernic BounGouendji Lebouma (Gabon/Congo) and Karim Sankara (Burkina Faso) through programs like IMU-CDC and AFRIMath. Labs and Teams Maire is part of the Mathematics group at the FEMTO-ST Institute, actively contributing to projects like MASPIN (Maths at FEMTO-ST). His work integrates theoretical research with applied areas such as coding theory, leveraging algebraic structures from number fields.
