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 in 2014. I was a Postdoctoral Fellow in Cambridge. In 2018, I became an independent group leader, founding the Di Martino Lab in the Department of Physics, University of Cambridge, after being awarded the prestigious Winton Advanced Research Fellowship. In 2020, was appointed Assistant Professor in Device Materials at the Department of Materials Science & Metallurgy and then became Associate Professor in 2023. I am now also Head of the Device Materials Group (DMG), which counts two other Principal Investigators. The Di Martino group's research is based on novel optical properties of nanostructured materials, including new physics and devices. My grants portfolio counts EPSRC, Leverhulme, Isaac Newton Trust, Royal Society grants and also an ERC starting grant.

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.
