Scalable Software Development for Predictive Atomistic Simulations

Scalable scientific software linking electronic structure, dynamics, and community methods development.

Why it matters

Predictive atomistic science depends on software that is scientifically rigorous, algorithmically efficient, and usable by a wider research community. Method development only becomes influential when it is implemented in codes that other researchers can adopt, test, and extend.

What I’ve done

My work includes scalable method development in FHI-aims, including real-space electron-phonon coupling, superconductivity workflows, phonon linewidths, and MPI-parallel friction tensor calculations. These efficient implementations are designed to make advanced methods practical for larger unit cells, more complex materials, surfaces, and low-dimensional systems. I also contribute to the broader software ecosystem around atomistic simulation, with an emphasis on maintainable implementations, interoperability, and tools that connect electronic structure to dynamics.

What I aim to do in the future

I want to treat software as core research infrastructure rather than support work. The long-term goal is to build open, high-quality platforms that make advanced real-space electron-phonon, superconductivity, and nonadiabatic-dynamics methods routine for surface chemistry and materials discovery, and to integrate them with AI and ML acceleration so that key observables can be computed at realistic scale without giving up physical transparency.
