Specially Appointed Assistant Professor at Nagoya University
Nagoya, Japan
Summary
👤
Senior🎓
Top SchoolJohannes Hörmann is a computational tribologist and data steward with a decade of experience bridging atomistic simulation, continuum modeling, and data infrastructure for materials science. His PhD work and MD/FEM models tackle friction and solvent effects at rough interfaces, while he has applied ML (GPC/GPR) commercially to predict surface finish performance as co-founder and CTO of a startup. He co-developed and maintains the community dtool & dserver ecosystem and has contributed backend and build-system improvements to high-profile open-source projects like LAMMPS and Fireworks, enabling parallel I/O and richer workflow tasks. Based in Nagoya, he blends hands-on code and scientific rigor with policy and reproducible workflows, and uniquely pairs tribology expertise with practical data stewardship across academic and entrepreneurial settings.

Role in this project:
Back-end Developer
Back-end DeveloperContributions:51 commits, 19 PRs, 12 comments in 1 year 9 months
Contributions summary:Johannes primarily contributed to the `fireworks` library's back-end functionality. They made changes to the `filepad` utility, modifying file access methods and adding sorting capabilities. In addition, the user introduced new filepad tasks like `GetFilesByQueryTask` and corrected typos, improving code quality and expanding the toolset. Furthermore, the user worked on integrating external code from a forked project to improve workflow.

Public development project of the LAMMPS MD software package
Role in this project:Back-end Developer
Back-end DeveloperContributions:6 commits, 2 PRs, 1 comment in 20 days
Contributions summary:Johannes primarily focused on modifying and updating CMake build files within the LAMMPS project. Their contributions involved finding and integrating NetCDF and Parallel NetCDF (PNetCDF) libraries for use within the LAMMPS build system. These updates enable the LAMMPS software to support NetCDF output for data analysis and visualization, as well as parallel I/O using PNetCDF. The changes included modifications to `FindNetCDF.cmake` and `FindPNetCDF.cmake` modules, and adjustments within `USER-NETCDF.cmake`.
