About
Sebastian XHONNEUX is a faculty member in the Department of Management Sciences at the School of Management, University of Namur. He actively teaches Mathematics for Economics and Management (EFASB231) for the 2023-2025 academic years, demonstrating his ongoing institutional engagement.
His educational credentials include a Bachelor's degree in Mathematical Sciences, a Higher Secondary Education Aggregation (AESS in Mathematics-Physics), and a Doctor of Science. These qualifications underpin his dual expertise in theoretical mathematics and pedagogical methodology.
XHONNEUX's research centers on nonlinear optimization and mathematics teaching, with distinctive focus on didactic transposition of mathematical concepts between disciplines. His work analyzes Lagrange's Theorem across mathematics and economics education, addressing challenges in secondary-to-university transitions and curriculum design. He emphasizes practical applications in management contexts through exercise collections and computational tools.
His 2009-2012 publications reveal consistent interdisciplinary themes: didactic analysis of Lagrange's Theorem, development of mathematical reasoning materials, and MATLAB programming education. These works demonstrate systematic efforts to bridge theoretical concepts with economic applications while improving pedagogical approaches in quantitative disciplines.
Though no formal awards are documented, XHONNEUX has supervised doctoral and master's theses while contributing to two major research projects. He served as researcher in proximal-type optimization methods (2004-2007) and institutional analysis of Lagrange's Theorem transposition (2007-2011), securing sustained project funding.
He maintains active community engagement through conferences including APMEP National Days and Belgian Mathematics Teachers' Congresses. His workshop participation in Groupe SUP initiatives focuses on secondary-university transition challenges, reflecting commitment to collaborative improvement of mathematics education in management training.
