Current Research Areas:

My team works on both fundamental and applied research and on both experimental and computational research related to metal additive manufacturing. Our current research areas mainly include:

Manufacturing

  • Improving the manufacturing capabilities of existing laser-based additive manufacturing (AM) processes.
  • Developing new manufacturing methods – hybrid AM processes – that incorporate secondary processes (e.g., micro-rolling) and/or heat resources (e.g., induction heating) to transform AM technologies.

Materials

  • In-situ synthesizing advanced metallic and metal-based materials using AM and hybrid AM processes.
  • Convergent manufacturing of dissimilar materials.
  • Resolving the metallurgical defects in AM-fabricated alloys and materials.

Physics-based simulations

  • Multi-scale microstructure modeling.
  • Crystal plasticity finite element modeling.
  • AM process modeling.

Data-driven modeling

  • Process optimization.
  • Defect control.
  • Material design.
