Our research focuses on Electro-Chemo-Mechanics of materials for next-generation applications in energy storage, electronics, and multifunctional devices. The question driving our research concentrates on how the structure and chemistry of materials at the atomic/molecular level control their performance in practical applications. To address this, we employ various modeling and simulation methods ranging from Quantum Mechanical Methods (e.g., Density Functional Theory), Molecular Dynamics, Monte Carlo, Machine Learning, using massively parallel computing facilities.
Our current research interests are in the area of modeling of energy storage systems such as rechargeable batteries, mechanics and electronics of nanomaterials (e.g., graphene) and other two-dimensional materials such as Transition Metal Dichalcogenides (TMDs), modeling of imperfections in crystalline materials, and nanomaterials for biological problems.
