Research Interests

Dr. Berrens’s research focuses on leveraging high-performance computing to apply advanced computational simulation methods-including classical molecular dynamics, first-principles electronic structure techniques, and machine-learning-accelerated models-to investigate materials under extreme conditions and at complex interfaces at the atomic scale. Her research is driven by the goal of developing a fundamental and predictive understanding of these systems to enable molecular-level interpretation of experimental results and guiding future experimental design. Specific examples include:

  • Performing large-scale molecular dynamics simulations to compute and interpret vibrational spectra of ice surfaces.
  • Investigating the structural, dynamical, and electronic properties of aqueous systems under extreme confinement within two-dimensional materials.
  • Benchmarking widely used equation-of-state and ionic transport models in the warm dense matter regime.
