Biography

Mauro focuses on the mathematical, numerical and computational treatment of Partial Differential Equations (PDE) that arise from various applications, PDE constrained optimization and recently in uncertainty quantification. Mauro has extensive experience with the Galerkin finite element method for discretizing PDEs, and he has been also working on mesh-free methods, in particular on Smoothed Particle Hydrodynamics and Generalized Moving Least Squares. He is interested in the design and analysis of numerical methods and the mathematical analysis (existence/uniqueness results) of PDEs. Mauro is the lead of the Trilinos Discretization and Analysis product.

More recently, Mauro has been working on Scientific Machine Learning, with the goal of combining learning techniques with well established numerical methods.

  • Ice sheet dynamics: Development of a finite element multi-physics implementation (FELIX) of equations governing ice dynamics, including nonlinear Stokes-like equations for ice-flow and enthalpy equation for ice temperature . Solution of PDE constrained optimization to invert for unknown/uncertain parameters by minimizing the mismatch with observed data and climate forcings. The code is written in Albany application and relies on several Trilinos packages.
  • Meshless discretization: Analysis and development of consistent and compatible meshless discretizations using generalized moving least square methods. Main targets are elliptic and transport equations and data-transfer problems.
  • Intrepid2: Development of a finite element library that provides performant and portable high-order finite element discretizations spanning all the De Rham complex. The code is a refactoring and enhancement of the library Intrepid.
  • Physics Constrained Learning Machines: Investigating the role of deep learning in modeling (or enhancing current models for) scientific problems. Specifically targeting ice sheet modeling and designing surrogates based on neural operator networks.

Education

  • PhD in Mathematical Engineering at Politecnico di Milano, Italy, in 2009.
