Research Interests

Since I started at LLNL in 2010, I've been involved in predicting the strength of metals using dislocation dynamics simulations. I've been developing the ParaDiS capability. ParaDiS models the evolution of dislocation lines into highly complex microstructures in response to an external load. Designed to run on massively parallel supercomputers, ParaDiS allows researchers to follow tens of thousands of simulated dislocations in a several micrometer-long cube over several seconds with periodic boundary conditions.
