My research interest uses nuclear magnetic resonance (NMR) to probe the local environment of defects in crystals of CdF 2 :Ga and CdF 2 :Ga,Y which have been reduced in a cadmium vapor. These defects exhibit unusual metastable properties that can be explained by a "negative U" model. In my dissertation work, temperature dependent relaxation measurements were done on 113 Cd in both crystals and 19 F in the gallium doped crystal. The relaxation of 19 F was attributed to shallow donors while the relaxation of 113 Cd was attributed to the concentration of electrons in the conduction band. In addition, NMR was used to observe the gallium impurity in and unreduced crystal.
My interest in teaching physics started during my graduate work at Oregon State University. White at OSU I built upon my teaching assistant experience by teaching classes for the Saturday Academy and Adventures in Learning, two outreach programs. I was also a Fellow for the GK-12 program sent me to teach, and by taught by, Carroll Nelson, a middle school algebra teacher in Corvallis, Or. My tenure as a GK-12 Fellow found me collaborating with Dr. Michael Rogers (Ithica College) and Matthew Stephens (Highland View Middle School, Corvallis, Oregon). We expanded upon Mr. Stephen's Physics and Roller Coaster Curriculum and have created a set of four manuals, three for student use (concepts, problems, and activities) and one for teachers. My current plan is to implement these activities here at Duquesne.
