About

I work as Staff Scientis at Lawrence Livermore National Laboratory. I also serve as a Director of the Materials Genome Foundation along with Richard Otis and Zi-Kui Liu.

I am interested in many things, but mostly I love building tools and solving problems. An (infrequently updated) CV can be found here.

Projects I work on

  • PyCalphad: PyCalphad is a computational thermodynamics library that I co-lead with Richard Otis and is the foundational computational engine for our PyCalphad software ecosystem.
  • ESPEI: ESPEI is a tool for developing Calphad-type models that I developed during my Ph.D. and continue to lead. We use it to investigate approaches for model parameterization and calibration such as uncertainty quantification and gradient-based methods.
  • phasediagrams.org: a project I was inspired to start after seeing Bengt Hallstedt's binary dataset collection paper. It is a PyCalphad-powered site to freely provides Calphad databases and phase diagrams.
  • try.pycalphad.org: a JupyterLite deployment where anyone can try out the PyCalphad ecosystem without installing anything. All content and notebooks run locally through webassembly. Repo is open source.
  • TAOS: a GUI-based materials design and selection software commercialized by LLNL. Led by AurĂ©lien Perron.
  • LLNL's Materials Acceleration Platform: I lead development of this proprietary LLNL tool for deploying ICME design tools to HPC systems.
