My research advances the understanding, design, and discovery of materials through computation and AI, targeting critical materials problems that limit high-impact technologies such as energy storage, conversion, and computing. Our computational modeling delivers fundamental physical insight and the ability to rationally design new materials.

Accelerated materials design and discovery through computation and AI/ML. We combine high-throughput first-principles computation with machine learning to design and discover materials, evaluating the full set of properties — phase stability, electrochemical stability, interface compatibility, synthesizability, thermal and moisture stability — that determine whether a material actually works in application. This approach has led to the discovery of new solid-electrolyte chemistries, including mixed-anion oxyhalide Li-ion conductors and Na-ion-conducting chloride families, several of which have since been confirmed experimentally and, in one case, patented industrially.

Understanding and designing materials interfaces in energy storage systems. Interfaces are often the limiting factor in battery performance and processing. We use first-principles thermodynamics and large-scale atomistic simulation to reveal how solid-electrolyte/electrode interfaces degrade, how Li stripping and plating proceed and fail at the atomic scale, and how protective coatings can stabilize these interfaces — with several predictions (interfacial amorphous Li layers, amorphous-to-BCC Li deposition pathways) since confirmed by experiment.

Large-scale atomistic modeling of complex materials phenomena. Large-scale atomistic simulation captures materials behavior governed by long length and time scales that are inaccessible to first-principles methods alone. We apply this to Li/Na/Mg/Zn metal-anode failure and crystallization mechanisms, disorder-to-order transitions in high-entropy nanoparticles, and mechanical deformation and friction at interfaces.

Trustworthy, interpretable AI/ML for materials science. Rather than treating machine learning as a black box, we develop AI/ML methods that are rigorously tested, physically interpretable, and capable of revealing new mechanisms — including application-oriented benchmarks for machine-learning interatomic potentials and our Density of Atomistic States (DOAS) framework for quantifying disorder and frustration in ion transport.
