معرفی
Pierre-Antoine Absil is a Full Professor at the Louvain Polytechnic School (EPL), part of the Université catholique de Louvain (UCLouvain), affiliated with the Mathematical Engineering Center (INMA) and the Institute of Information and Communication Technologies, Electronics and Applied Mathematics (ICTEAM). His research spans Riemannian optimization, matrix manifolds, and low-rank approximation with applications in astronomical imaging, signal processing, and environmental data imputation.
His work emphasizes
- Riemannian optimization algorithms
- matrix and tensor completion
- geometric data analysis
- applications in astrophysics and bioinformatics
Recent publications focus on Stiefel and Grassmann manifolds, variable projection methods, and exoplanet detection via alternating minimization. While no explicit scientific awards are listed, his collaborations with institutions like IEEE and Springer highlight his impact in computational mathematics and engineering.
He has supervised researchers such as Simon Vary, Guillaume Olikier, and Valentin Christiaens through projects in direct imaging, economic dispatch, and graph-based data processing. His laboratory, INMA, drives methodological advances in manifold-valued data analysis and nonlinear optimization.
