Summary
👤
Senior🎓
Top SchoolNagaso Masaru is a research-focused software engineer with 11 years of experience building high-performance numerical codes for acoustics, seismology and statistical modeling, specializing in HPC and GPU-accelerated systems. Currently a Research Fellow at the Earth Observatory of Singapore and Nanyang Technological University, he leads development of TomoATT and eikonal-based adjoint-state travel-time tomography libraries optimized for Exascale workflows, MPI/GPU execution, and parallel HDF5. His background spans academic and industry projects—from SPECFEM3D I/O and full-wave inversion work for EU Exascale initiatives to spectral-element simulations for reactor acoustics—combining deep numerical analysis with pragmatic engineering (containerization, SIMD, MPI-SHMEM). Comfortable across C++, Python, parallel I/O and modern web stacks (React/MongoDB), he bridges research and production to run very large, realistic simulations on cutting-edge infrastructure. An unusual detail: he pairs scientific code development with hands-on web tooling for university services, reflecting a blend of low-level performance tuning and user-facing software delivery.

SPECFEM3D_Cartesian simulates acoustic (fluid), elastic (solid), coupled acoustic/elastic, poroelastic or seismic wave propagation in any type of conforming mesh of hexahedra (structured or not). It can for instance model seismic waves propagating in sedimentary basins or any other regional geological model following earthquakes. It can also be used for non destructive testing or for ocean acoustics.
