Dr. Kaspar joined PNNL as a graduate student in 2000. After graduation, she remained as a post-doctoral researcher, and was hired as a full-time staff scientist in Scott Chambers' Oxide Epitaxy group in 2007.

Dr. Kaspar's research interests include the epitaxial growth (via oxygen-plasma-assisted molecular beam epitaxy or pulsed laser deposition) and structural characterization of metallic and metal oxide films. Structure-property relationships can then be made with physical phenomena such as magnetic and electronic properties. Previous work focused on the magnetic properties of transition-metal-doped TiO2 and ZnO as potential dilute magnetic semiconductors. More recent work has investigated the electronic, photoactive, and magnetic properties of doped binary and complex oxides. Other recent research areas have included the structural characterization of lattice-mismatched epitaxial metal films on oxide substrates for radiation damage studies, electronic characterization of ZnO-based materials relevant for solar photovoltaics, and pulsed laser deposition of complex oxides for solid oxide fuel cell applications.
