Dr. Krause is an expert in non-destructive testing (NDT) of materials using eddy current and ultrasonic techniques.

Thomas W. Krause received the B.Sc. degree from the University of Calgary, Calgary, AB, Canada, in 1987, and the M.Sc. and Ph.D. degrees from McMaster University, Hamilton, ON, Canada, in 1989 and 1992, respectively, all in physics. He was with the Applied Magnetics Group, Queen's University, Kingston, ON, Canada, from 1992 to 1996. In 1996, he held a position as Physicist with Canadian Nuclear Laboratories, developing non-destructive testing technology for the nuclear industry. In 2006 he accepted a position as Associate Professor with the Royal Military College of Canada. In 2008 he was promoted to full professor. He has 24 years of research and development experience on advanced NDT technology including pulsed eddy current, eddy current, magnetic Barkhausen noise, and ultrasonic testing of materials and structures.

R&D in NDT includes laboratory experimentation and computer modeling in the area of:

  • Eddy current testing
  • Multi-frequency eddy current testing
  • Pulsed eddy current
  • Remote field eddy current
  • Probability of detection
  • Ultrasonic testing
