Research

My research mainly focuses on processing-microstructure-property correlation in metallic alloys. In specific, I am actively working on following research topics.

  • Deformation mechanisms during high strain rate deformation of alloys.
  • Mechanical and microstructural characterization of additively manufactured alloys.
  • Deformation mechanisms in high entropy alloys.
  • Microstructure based probabilistic modeling for fatigue life estimation.
  • Friction stir welding/processing and solid-state processing.
