Nanoplasmonics for materials innovation

About me

My research career started in Italy at the Scuola Superiore di Eccellenza and University of Catania. I spent part of my Master studies at Boston University and completed my PhD at Imperial College London. My recognition on an international scale in the plasmonic community led to several awards (CSWP Woman Physicist of the Month from the American Physical Society and the 2014 ABTA Doctoral Researcher Award). I was a Postdoctoral Fellow in Cambridge and later on I became an independent group leader at the University of Cambridge, at the Cavendish Laboratory, after being awarded the prestigious Winton Advanced Research Fellowship in 2018. I was appointed as Lecturer in Device Materials at the Department of Materials Science & Metallurgy at the beginning of 2020.

Research interests

My research links the fields of low-energy nanoscale device engineering and plasmon-enhanced light-matter interactions by implementing optically-accessible memristive devices. My research group uses the ultra-concentration of light to develop innovative fast ways to study real-time movement of individual atoms that underpins this new generation of ultra-low energy memory nano-devices, thus overcoming the limitations of traditional investigation techniques and opening up new routes to sustainable future IT.
