AI/ML for Electronic Structure

Generative and surrogate models that accelerate GW/BSE workflows across heterogeneous materials platforms.

Quick Summary

Generative and surrogate models shorten the feedback loop between expensive many-body perturbation theory and design-ready predictions. I am combining reduced-order models for the screened Coulomb interaction with machine-learned mappings that predict quasiparticle corrections, excitonic responses, and dielectric screening for complex interfaces.

Current Focus Areas

  • Latent-space surrogates that approximate GW/BSE excitation energies across large chemical subspaces.
  • Uncertainty-aware models that flag regions requiring direct many-body calculation.
  • Workflows that couple PyTorch-accelerated inference with WEST/BerkeleyGW on leadership-class systems.

Selected Outputs

Next Steps

I am integrating data-assimilation pipelines that combine experimental photoluminescence spectra with theoretical priors, and extending the surrogate models to handle strongly anisotropic interfaces.
