Thin-film thickness from spectroscopic ellipsometry: a differentiable transfer-matrix forward model in PyTorch, a Levenberg–Marquardt baseline, and a learned inverse model with calibrated uncertainty benchmarked against the Cramér–Rao bound.

Physics-based framework for creep, fatigue, and creep–fatigue life prediction of Inconel 718, with calibrated models, finite-element simulations, and a lightweight app.

Generative molecular design of sustainable single-phase immersion cooling fluids with ML and physics-based validation.

A paper-to-digital-twin MVP for reconstructing materials-science battery experiments from research papers, simulating them, scoring replication, and exploring parameter changes in an interactive sandbox.

Molecular dynamics study of lithium diffusion in pristine and defective silicon–graphene composite anode models using LAMMPS.
