Dr. Hamann has expertise in the areas of electrochemistry, photoelectrochemistry, nanostructured materials, and materials characterization. She has experience with general electrochemical methods as well as numerous materials characterization techniques including scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), atomic force microscopy (AFM), and X-ray diffraction (XRD).

Dr. Hamann is interested in applying this knowledge to understand and characterize corrosion and failure of materials, particularly at the nano-/microscale.

Dr. Hamann completed her doctoral work at Caltech where she developed light-directed electrodeposition techniques for the generation of highly ordered mesostructured semiconductors. As a National Science Foundation (NSF) Fellow, she expanded the materials accessible via the technique and investigated how optical inputs could be adjusted to direct the synthesis of unique and complex nanostructures with multidimensional anisotropy.
