Yvonne Maria Jose worked on the glotzerlab/freud repository, focusing on refactoring the density module to enhance its API surface and improve memory management. She updated CMake exports for CorrelationFunction and GaussianDensity, aligning the Python interface for more robust downstream integration. Using C++, CMake, and Python, Yvonne introduced a new toNumpyArray() method to streamline data access and return, while also reducing the memory footprint in key components. Her work emphasized software refactoring and build system improvements, laying a foundation for future performance optimizations and maintainability. The changes addressed API stability and usability, supporting more reliable scientific workflows.
