Alessandra Bellissimo's main research interest concerns the fundamental mechanisms governing electron interaction, generation, and emission from solid surfaces. Her current scientific focus lies in unravelling the electron dynamics of complex many-body processes, in particular of plasmon excitations, which play a pivotal role in secondary electron emission. With a background in Physics from the Technical University in Vienna (AT) and a PhD in Material Sciences, Nanotechnology, and Complex Systems from the University of Roma Tre (IT), Alessandra has explored the field using several spectro- and microscopic techniques; i.a. electron-pair spectroscopy to investigate the correlations between plasmon excitations and the ejection of secondary electrons; scanning field-emission microscopy, which enables to both image the surface topography, and detecting the spectroscopic signal of those electrons escaping the tip-surface tunnel junction. Presently, she leads a project at the Institute of Photonics at TU Wien where time-resolved photoelectron spectroscopy from solid surfaces is employed to establish the causal link between collective electron excitations and SE-emission channels.
