At the Institute of Biomedical Engineering (IBT) of KIT, I contribute to the development of high-performance software tools for simulating cardiac electrophysiology. This work is part of the open-CARP and the European MICROCARD project, aiming to enable accurate, scalable simulations of the human heart in realistic three-dimensional geometries.
These simulations model the electrical behavior of cardiac tissue by solving reaction-diffusion equations; a computationally intensive task that requires modern high-performance computing (HPC) infrastructure. My focus is on bridging scientific modeling with software engineering to ensure that these tools are not only efficient, but also robust, maintainable, and reproducible.

My contributions include:
• Refactoring and optimizing core components of the C++/MPI simulation code;
• Implementing automated testing, performance benchmarking, and documentation workflows;
• Supporting GPU integration and exploring hybrid CPU-GPU execution models;
• Working with the openCARP community to improve usability and scientific transparency.

The overarching goal is to provide researchers and clinicians with reliable, scalable simulation tools that support advanced cardiac modeling, from individual studies to large-scale patient cohorts.
