Research Interests:

I am interested in computer modeling of materials on an atomic or molecular level. The tools I am using are molecular dynamics and Monte Carlo techniques in order to study defect properties in solids. I am interested in force field development, algorithms for optimization and code development to optimally compute long-time processes such as diffusion or friction in solids (on the order of microseconds instead of nanoseconds). All simulations are performed on a Beowulf cluster with currently 32 CPUs, dedicated exclusively to this purpose.


Current Projects:

  1. Computer Model of interfaces under normal and shear stress.
  2. Defects in RDX:

Currently my work focuses on point defects in the molecular solid RDX. This is a powerful explosive with the caveat of a high sensitivity. Defects in the crystalline lattice provide places at which detonations seem to originate due to their energetically predisposed position. The crystals are produced from solution, and often defects are incorporated during the crystal growth. Limiting the amount of defects can help lower the sensitivity, hence our model studies how the defects are formed, which geometry they have, how easily they heal or diffuse, and how growth conditions influence their concentration. The project originates from an initiative from Lawrence Livermore National Lab, trying to solve the problem of stockpile of weapons from the cold-war era. The weapons are aging, and need to be dealt with. Rather than experiment with these stockpiles, a computational initiative has been started to model the materials and their behavior, hence helping to decide the best course of action. Take a look at the vibrational properties of the RDX molecule.
