Hello! 👋

I'm Ryo Ide

SciML Researcher · Physics-Informed Machine Learning

About Me

I'm a Physics and Data Science student at UC San Diego researching scientific machine learning, physics-aware deep learning, and computational physics. My work spans PINN and neural-operator surrogates for thermal simulation, characteristic-aligned operators for transport-dominated PDEs, and MCMC-based analysis of lattice field theory — with published research in AI Interpretability and on Computational Physics. I'm looking for roles in SciML research, physics-informed ML, or quantitative research, where rigorous math meets real systems.

Experience

Engineering Intern

Bucket Labs

Jun 2026 - Aug 2026
  • Built PINN and ResGRU surrogates for PC thermal simulation; Optuna hyperparameter tuning reduced RMSE from 20 to 4
  • Identified and fixed data-leakage bugs in a physics-informed neural operator; rebuilt the pipeline to achieve a fair 0.75°C RMSE
  • Conducted causal ablation study; concluded Performer attention added no real gain (+2.5%) and removed it to reduce model complexity

Undergraduate Researcher

Prof. Tajana Rosing Lab / SEELab, UC San Diego

Apr 2026 - Present
  • Developing characteristic-aligned neural operators for transport-dominated PDEs in fluid dynamics, learning only the residual kernel left after known transport is removed
  • Derived approximation lower bounds linking kernel rank to transport separation; experimentally showed effective kernel rank grew O(1) for characteristic-aligned architectures versus sub-quadratic growth for generic kernel methods

Undergraduate Researcher

Prof. Javier Duarte Lab, UC San Diego

Feb 2026 - Present
  • Characterized regime-dependent failures of independence-based models in lattice φ⁴ theory: sampled fields via Metropolis-Hastings MCMC and benchmarked Fourier, PCA, and normalizing-flow representations
  • Quantified mode coupling growth of ~3x (C: 0.06 to 0.2), defining 3 regimes for when nonlinear models are needed; released as an arXiv preprint and presented at the 2026 Conference on Physics and AI, Stanford

Adversarial Robustness for Deep Learning-based Wildfire Prediction

Built WARP, the first model-agnostic adversarial robustness evaluation method for wildfire smoke detectors (YOLOv8n vs RT-DETR). Global Gaussian noise cut transformer mAP to 86.5% vs 50.8% for CNN; adversarial inputs reversed ~50% of smoke detections. Published in Fire.
