Hariprashad Ravikumar
Computational physicist building GPU-accelerated ML and simulation tools.
I turn large-scale physics simulations into software that engineers actually use. At Western Digital I derived closed-form models for heat-assisted magnetic recording from first principles and shipped HAMR DCSNR NIMBLE app, the simulator that the team now runs across sites in the US and Japan.
My PhD at New Mexico State University applies GPU-accelerated HPC and machine learning to lattice QCD with 30,000+ observables, CUDA C++ pipelines, and symbolic regression that recovers analytical structure from noisy Monte Carlo data using HPC (High Performance Computing).
Western Digital · San Jose, CA · Summer 2026
I built NIMBLE, a HAMR simulator now used by 40+ engineers across WD's US and Japan sites.
Over summer 2026 I derived closed-form analytical models for grain magnetization dynamics in Heat-Assisted Magnetic Recording from first principles, predicting adjacent-track erasure (ATI & xTI) without costly hardware experiments.
I shipped the physics as NIMBLE, a production Dash/Plotly simulation platform packaged as a modular Python library, deployed on Kubernetes with Jenkins CI/CD and adopted by sputtering and media engineering teams.
