About

I am Louis Touzalin, also known as at0m741. My background comes from low-level programming, systems work, and the École 42 environment, with a strong focus on understanding how software behaves close to the hardware boundary.

I work primarily with C and C++, SIMD-oriented code, high-performance computing, compiler infrastructure, and numerical methods. My current work includes Tensorium_lib, compiler and DSL experiments for tensor calculus, and MLIR-based explorations around lowering, vectorization, and backend design.

Research direction

I am interested in numerical relativity, general relativity, black hole simulations, tensor calculus, and the engineering required to make these ideas executable at high performance.

A recurring theme in my work is building tools that connect theoretical physics with practical computation: data structures, kernels, compiler passes, and workflows that can scale from experiments to serious numerical code.

Systems work

I use systems programming as a way to make numerical and compiler ideas concrete: data layout, memory behavior, vectorization, runtime constraints, and the engineering details that decide whether an implementation remains practical.
