My primary scholarly activities are magnetic materials research and physics education. In particular, I have recently been using magnetic domain imaging and magnetometry to investigate nanostructured ferromagnets, including granular Co-Ag, granular Ni-Al2O3, and Nd-Fe-B.

Physics Education

  • Co-developer of the Just-in-Time Teaching (JiTT) instructional method
  • Studies of personal response systems, online forums, online homework, and other educational technologies
  • Faculty professional development
  • Director, Bridges to the Baccalaureate in Central Indiana
  • Curriculum development


Condensed Matter:

  • Design and development of an advanced thin film deposition system for materials research.
  • Magnetic domain imaging as a microstructural probe in Nd-Fe-B magnetic materials.
  • Dynamic Magnetic domain imaging for development of amorphous magnetic materials for transformer applications.
  • Development of a magnetron sputtering based nanoparticle source for high resolution Bitter microscopy.
  • Magnetometry, x-ray diffraction, and other probes of nanostructured metal-insulator and metal-metal composites and multilayers
