Current position

Research engineer at ISAE-SUPAERO in the Applied Mathematics group of DISC since September 2016.

Past position

Senior scientist in the Parallel Algorithms Project at CERFACS.


  • We have organized the workshop "Massively parallel methods for data-driven modelling and simulation in computational mechanics" in September 2020. A big thanks to all the speakers and (virtual) attendees !
  • Congratulations to Dr. Thibaut Lunet for the Paul Caseau PhD prize !

 Research interests

My primary research interests are related to scientific computing and concern the design and analysis of parallel algorithms for the solution of partial differential equations and related high-dimensional linear algebra problems.

  • Fast iterative solvers for large systems of linear and nonlinear equations
  • Krylov subspace methods and preconditioning
  • Multigrid and domain decomposition methods
  • Parallel computing including parallel in time methods

A summary of these activities is given in my Habilitation thesis (HDR manuscript) of June 2016.

My current research deals with high performance and large scale computations with a focus on the analysis of data from scientific simulations.


A complete list of publications is available on my ORCID page.

 Current project

  • PhD thesis of Alexandre Scotto di Perrotolo with Youssef Diouane and Michel Salaün. (starting November 2018). Funding from ISAE-SUPAERO.

 Past projects

  • TTIL project (September 2019 - December 2020) with Youssef Diouane and Michel Salaün (ISAE-SUPAERO), Robin Bouclier (INSA Toulouse) and Jean-Charles Passieux (INSA Toulouse) on numerical methods for Digital Image Correlation with application to mechanics.
  • INFIDHEM ANR-DFG project on port-Hamiltonian systems. (February 2017 - December 2020).

 Teaching activities at ISAE-SUPAERO (academic year 2021-2022)

I am involved in the following lectures for the third year SXS students (Master 2) :

  • D-SXS313 - High Performance Computing

for the second year students (Master 1) :

  • TCS3-MA - Applied mathematics - Partial Differential Equations : theory and numerical simulation.

I am also the contact person for the PIE (Projet Ingénierie et Entreprise) for the third year SXS students.
