Biography: 

Vaso Tileli is a Marie Curie Intra-European Fellow at Imperial College London. She has extensive experience at nanomaterial characterization using advanced transmission electron microscopy techniques. Currently, her research, funded by the People Programme (Marie Curie Actions) of the European Union's Seventh Framework Programme (FP7/2007-2013) under REA grant agreement n° [301838], focuses on electron probing of functional oxides. Ferroelectric and multiferroic materials have become technologically important due to their wide range of applications including high frequency electronics, microwave tunable devices (i.e. phase shifters, filters, delay lines), and memory based devices. Attributes such as defects density, stoichiometry, chemical bonding, and space charge distributions of oxides like barium titanate and cobalt ferrite are investigated using negative spherical abberation imaging, electron energy-loss spectroscopy, and electron holography.
