Links and information related to my work. See Recent news & updates below.

Professional background · 17 December 2015

I am a research scientist in the Computational Engineering and Energy Sciences Group in the Computer Science and Mathematics Division at the Oak Ridge National Laboratory. I have adjunct faculty appointments with University of Tennessee Knoxville and UT Chattanooga. I work mostly on integration of computational models and experimental techniques for solving materials-related problems.

Research interests

  • Modeling and testing of materials and structures under impact loading
  • Damage, fracture, and failure in materials and structures
  • Strain-rate sensitivity in lightweight materials
  • Size effects, localization, scaling of strength and fracture
  • High performance computing
  • Modeling of multiphysics and multiscale phenomena
  • Modeling of heterogeneous chemically reacting flows
  • Modeling of carbon-fiber composites manufacturing
  • Thermodynamics of nuclear materials
  • Modeling of Li-ion batteries
  • Parallel time integration for power systems dynamics
  • Modeling of additive manufacturing
