PROFILE
Xin Kai Lee
Over a two-month period, contributed to the CliMA/Oceananigans.jl repository by enhancing diffusion modeling and distributed grid reconstruction. Developed clock-based time-stepping for TriadIsopycnalSkewSymmetricDiffusivity, introducing a closure-field builder and updating inline functions to improve simulation accuracy and reproducibility. Implemented the with_number_type utility to enable correct reconstruction of distributed grids using local and global parameters. Addressed a stability issue in the diffusive Gent-McWilliams model by refining the tapering function and adding targeted tests to prevent NaNs in buoyancy fields. Demonstrated expertise in Julia, scientific computing, and numerical modeling, with a focus on robust testing and code review practices.

Dec 1, 2025December 2025 monthly summary for CliMA/Oceananigans.jl: Delivered substantive enhancements to diffusion modeling and distributed grid handling, with a focus on correctness, stability, and reproducibility. Key features implemented include: clock-based time-stepping for TriadIsopycnalSkewSymmetricDiffusivity with a new closure-field builder, updates to inline functions to use clock, and validation tests for the diffusivity; added with_number_type to correctly reconstruct distributed grids using local grid parameters and global arguments. Major bug fix: corrected the clock argument in TriadIsopycnalSkewSymmetricDiffusivity's explicit_R₃₃_∂z_c function (#4780). Overall impact: improves numerical stability and accuracy of diffusion simulations, increases reliability of distributed reconstructions, and strengthens test coverage. Technologies/skills demonstrated: Julia, clock-based timestepping, closure-field patterns, distributed grid reconstruction, and test-driven development.
