Biography

My name is Thibault Cimic, I’m a research engineer in applied Mathematics specialized in linear algebra and PDE solvers. My job consist of getting maths ideas into computers.

My last position was at CEA (ending in August 2024) as a HPC research engineer at Laboratoire Genie Logiciel, where I’ve distributed a high order spectral finite element code called Ondo for wave propagation modelisation on distrubuted memory architecture.

Before that I’ve been working in the ALPINES team at INRIA in Paris, France, lead by Laura Grigori. It’s a team both conjoint with INRIA (INRIA’s website here) and Laboratoire Jacques Louis Lions (LJLL) of the Sorbonne Université, science division (LJLL’s website here). There, I have developped 2-lvl precondionning techniques for an astrophysic problem called the map-making problem for the cosmic microwave background (CMB for short), you can find more details about that on my dedicated page : B3DCMB.

I’m not currently employed and looking for a position close the research field as a research engineer. You can download my resume just below. I’m right now working on open source projects I started for fun and practice like Lina or ECG.
