I am a postdoctoral researcher in the numerical analysis group at the STFC Rutherford Appleton Laboratory. I finished my PhD in 2015 at the Université Paul Sabatier Toulouse III on Task based multifrontal solvers for heterogeneous architectures and it was conducted in the context of the qr_mumps solver under the supervision of Alfredo Buttari.
My research interests lie in the domain of numerical linear algebra and high performance computing. I am particularly interested in the development of direct solvers for solving large sparse linear systems of equations. I am currently involved in the NLAFET project, a EU-funded Horizon 2020 project, aiming at improving the performance and scalability of linear algebra software for the emerging extreme-scale systems.
