Essential Duties and Responsibilities:
  • Advanced Simulation & Modeling
  • Develop and apply advanced simulation techniques, specializing in Reactive Force Fields (ReaxFF) and MD/DFT coupling, to model complex materials phenomena.
  • Conduct and analyze multi-scale computation projects, covering atomistic simulation up to mesoscale modeling.
  • Utilize and maintain advanced simulation tools, including VASP, LAMMPS, GROMACS, and CP2K, for high-fidelity simulations.
  • Perform rigorous physics-based validation on all simulation outputs to ensure accuracy and reliability.
  • AI Data & Workflow Development
  • Generate and validate high-quality atomistic and mesoscale datasets used for training ML potential and other scientific AI models.
  • Develop advanced simulation workflows and contribute to the creation of ML potentials and AI-driven materials discovery tools.
  • Coding & Collaboration
  • Apply strong coding skills (e.g., Python, C++, FORTRAN) to automate complex simulation workflows and enhance computational efficiency.
  • Maintain a solid understanding of battery chemistry modeling and collaborate effectively across computational and experimental teams.


Education and/or Experience:

  • Education: Ph.D. in Computational Chemistry of Energy Materials, Materials Science, or Computational Physics.
  • Core Simulation Expertise: Deep, demonstrated expertise in advanced physics-based simulation, including proficiency with DFT, MD, and Quantum Mechanics (QM) simulation tools.
  • Reactive Potentials: Proven experience with Reactive Force Fields (ReaxFF) and methods for MD/DFT coupling.
  • Coding & Tools: Strong coding ability in languages such as Python, C++, or FORTRAN, and deep practical experience with simulation codes like VASP, LAMMPS, GROMACS, or CP2K.
  • Domain Focus: Solid understanding of battery chemistry modeling and experience in generating and validating atomistic and mesoscale data.


Preferred Qualifications:

  • Machine Learning Integration: Experience with Neural Networks and Deep Learning, particularly in applying them to develop ML potential. Familiarity with geometric deep learning libraries like PyTorch Geometric is a plus.
  • Multiscale Methods: Experience with specialized methods like the Materials-Point Method.
  • Hybrid Literacy: Experience with experimental literacy, understanding characterization methods such as SEM, TEM, XPS, Raman, EIS, NMR, DSC, or TGA.
  • Background: Previous experience at advanced simulation labs, battery multiscale modeling groups, or in the computational chemistry of energy materials.
