Curriculum Vitae

Full Profile

Research Interests:

  • 3D Printing/Additive manufacturing of advanced materials.
  • Laser & electron beam melting technologies.
  • 3D materials science.
  • Nanoparticle health effects; especially soots, fullerenes, carbon nanotubes.
  • Materials aspects of ballistic and hypervelocity impact & penetration phenomena.

Research Description:

    Specialty powders and advanced alloy powders are used to fabricate complex, 3D monolithic components using electron and laser beam melting systems where CAD models selectively melt progressive powder layers. Special emphasis on open-cellular structures (mesh and foam products) which are being explored as next generation orthopedic implants having bone-compatible properties and conducive to bone-cell ingrowth. Microstructure-property relationships utilizing optical and electron microscopy and X-ray diffraction analysis are rendered in 3D image-property constructions. Research involving ballistic and hypervelocity impact and penetration, especially metal and alloy systems, has been a decades-long programmatic area. Recent research has focused on impact/penetration induced nanoparticulate debris, and respiratory health effects of inhaling this debris. Related studies of nanoparticulate soots, including fullerenes and multiwall carbon nanotube respiratory health effects have also been pursued over the past decade. Especially notable has been transmission electron microscope studies of nanoparticle and nanoparticle aggregate morphologies and corresponding cytotoxicity studies using human lung cell models.
