I study how seismic waves scatter in the heterogeneous crust, and how a hidden anomaly can be told apart from the random clutter around it. My path into geophysics started in electrical engineering: a B.Eng. in Electrical Engineering & Automation, then a year keeping the mission-critical power systems of a national government data center running. That background in signals, hardware and fault diagnosis shapes how I approach wave physics today.

seismic-model A 2D P-SV elastic finite-difference framework for wave scattering in random heterogeneous media, built from scratch in Python/NumPy. 4th-order staggered-grid solver with convolutional PML FFT-based stochastic media (von Kármán / Gaussian) P/S energy separation and coda analysis Independent Monte Carlo radiative-transfer model Energy conserved to within 0.6%; CI-tested and reproducible Findings: behind an 8 × 8 km anomaly, late coda energy rises +43% and S energy +54%; the P→S energy ratio grows ~50× as heterogeneity increases.
