Worked extensively on the glotzerlab/hoomd-blue simulation framework, delivering nine features and four bug fixes over eight months. Focused on improving rigid-body dynamics, parallel consistency, and simulation accuracy, the work included enhancements to MPI-based communication, GPU-accelerated routines, and mass handling for molecular dynamics. Leveraged C++, Python, and CUDA to implement new collision methods, configurable simulation parameters, and robust error handling for zero-mass constituents. Emphasized code maintainability through documentation updates, code refactoring, and comprehensive test coverage using pytest. These contributions improved simulation fidelity, reproducibility, and performance, supporting both CPU and GPU environments for high-performance scientific computing workflows.
