Who am I? The group leader, advisor, and task master for the Molecular Ferroelectrics Laboratory in the UNL Department of Physics and Astronomy.

For how long? I have been at UNL since Harald V became King of Norway.

How did I get here? I am from Massachusetts, graduated from Leominster High School (birthplace of John Chapman) and earned a Bachelor of Science in Physics at the University of Lowell (now The University of Massachusetts at Lowell, birthplace of Jack Kerouac). While studying at U. Lowell (go River Hawks), I ventured out of New England for summer undergraduate research experiences in nuclear physics at Oak Ridge National Laboratory in Tennessee and in superconductivity at Argonne National Laboratory in Illinois.
I  headed west to the University of Southern California (go Trojans) where I earned the Ph.D. in Physics for work on photorefractive nonlinear optical materials with Jack Feinberg. I broadened my professional horizons with appointments working on chalcogenide glasses and High-Tc superconductors with Craig Taylor at the University of Utah (go Utes) in Salt Lake City and on organic nonlinear optics with W. E. Moerner at the IBM Almaden Research Center (go Big Blue) in San Jose, California. I  then joined the faculty of the Department of Physics and Astronomy and the Nebraska Center for Materials and Nanoscience at the University of Nebraska—Lincoln (go Huskers).
