Molecular Dynamics of Glasses & Soft Particles

Large-scale LAMMPS simulations of metallic glasses under deformation and of deformable particles clogging in hopper flows.

Overview

In Prof. Corey O'Hern's group at Yale, first as a 2018 summer research fellow and then as a Ph.D. student from 2019 to 2021, I used molecular dynamics to study how amorphous and granular materials behave.

Projects

  • Bulk metallic glasses: simulated glass-forming ability and phase transitions, and calculated particle-rearrangement statistics under cyclic deformation to characterize ductility. Presented as "Encoding Multidirectional Memory in Sheared Amorphous Solids" at the 2018 Leadership Alliance National Symposium.
  • Clogging in hopper flows: modeled deformable particles with a soft-particle model to study when and how hopper flows clog, working with experimental collaborators.
  • Infrastructure: built parallelized simulation workflows on HPC clusters for large-scale computation.
