Research Interests

Nuclear materials, advanced reactors, materials chemistry, atomistic simulation, multi-scale modeling, machine learning, energy storage and conversion.

My research group focuses on combining multi-scale chemical simulation, informed experiments, and advanced data analytics for the purpose of understanding chemical structure, reactions and property relationships. This includes the development of new computational tools to improve fundamental understanding of material properties, increase the prediction accuracy of simulations, and accelerate materials screening and discovery.

The group's interests include:
  1. supporting the development of energy technologies using high heat capacity ionic liquids including solar thermal storage, advanced fission reactors and fusion reactors,
  2. understanding corrosion processes in nuclear systems,
  3. predicting engineering properties and thermochemistry from first principles,
  4. applying machine learning methods to improve and accelerate modeling and simulation methods (e.g. interatomic potentials, image processing, etc.).
