Maurice S. Fabien

Maurice S. Fabien is an Assistant Professor in the Department of Mathematics at the University of Wisconsin-Madison and a SIAM-MGB Early Career Fellow. In 2025, he will join MIT's Schwarzman College of Computing as an MLK Assistant Professor while on leave from UW-Madison. His research focuses on computational mathematics with specialization in partial differential equations, high-performance computing, and numerical methods including discontinuous Galerkin formulations and multigrid solvers.

Research interests span:

• Development of structure-preserving discretizations for hyperbolic systems
• GPU-accelerated computational algorithms
• Hybridizable discontinuous Galerkin (HDG) frameworks
• Multiscale modeling in porous media and biomechanics
• Numerical analysis of nonlinear PDEs

Publications demonstrate strong focus on:

• High-order methods for conservation laws
• Efficient solvers for elliptic/parabolic systems
• Applications in fluid dynamics and materials science
• GPU-based performance optimization
• Error analysis of energy-stable schemes

Awards & Honors:
SIAM-MGB Early Career Fellowship (2025)

Research Team:

• Austin Anyanwu (Undergraduate) - Finite precision arithmetic
• Alexis Liu (Alumni) - GPU-accelerated elliptic solvers
• Patrick Li (Undergraduate) - GPU-based mesh refinement
