Karen Sauer’s research interests

The Magnetic Resonance Laboratory (MRL) is directed by Dr. Karen L. Sauer, of the School of Physics, Astronomy, and Compuational Sciences. 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.
