Interest Areas

Expertise:
Electromagnetic NDE
EC
Research Interests:
Electromagnetic methods of NDE and the properties of electrically conducting composite materials. The work on electromagnetic NDE focuses on new and improved inspection methods for detection of cracks and corrosion in aircraft and nuclear power plants, and theoretical/computational models to support developments in eddy current inspection hardware.
