Dr Kalfagiannis is a Marie Curie Fellow under the Intra-European Fellowship scheme (supervised by Dr D Koutsogeorgis) hosted by the Electronic and Photonic Materials Research Group. His project, LASER-PLASMON deals with the LASER processing (and in particular nano-structuring) of metals and metal / dielectric complexes.

The main research topic lies on the cutting-edge field of plasmonics, which is one of the most dynamic and developing research fields, arising at the intersection of multiple fields: condensed matter physics, materials and physical chemistry, and electrical engineering, creating new capabilities for various applications. The group seeks to establish laser process as a tool for nanostructuring of metals and metal/dielectric complexes and create an experimental library of materials and processes that will be suitable for specific applications. These materials are of great interest for a number of forefront research areas (chemical and biomedical sensing, information and communication technologies, solar cells and lighting, cancer treatment, environmental remediation, optical encoding to name a few) due to their Localized Surface Plasmon Resonance (LSPR).
