About
Dr. Sauer, in addition to teaching physics courses, has an active research program in low-field magnetic resonance, including nuclear quadruple resonance and radio-frequency quantum magnetometers.
Current Research
The Magnetic Resonance Laboratory (MRL) is directed by Dr. Karen L. Sauer, of the Department of Physics and Astronomy. The research of MRL seeks to understand and exploit spin-dynamics in such systems as nuclear quadrupole resonance and optically pumped atoms. In addition, we conduct research to push the noise in such systems to their fundamental limit, to reveal the full capability of magnetic resonance at low-fields both as an analytic tool and for the detection of contraband substances.
Teaching Focus
Dr. Sauer teaches a variety of courses in Physics. http://physics.gmu.edu/~ksauer/teaching.htm
