Masiello’s interdisciplinary research group is best known for building simple yet rich theoretical models and numerical simulation tools to understand nanoscale optical, magnetic, electronic, and thermal phenomena mediated by surface plasmons. An overarching theme of their research is the fundamental science of light manipulation, especially in metamaterials capable of directing light towards desired pathways, such as optical-frequency magnetism, spatially-directed thermal patterning, room-temperature quantum information processing, and enhanced solar-energy conversion. The Masiello group is also known for elucidating cutting-edge electron microscopy experiments that use fast electrons as a spectroscopic probe of matter. This work in particular has provided significant insight into the optical-frequency responses of metallic and semiconductor materials from the nanoscopic down to the quantum-size regime, and their theoretical approaches are currently being used by the plasmonics and nanophotonics communities to direct the design of advanced materials with unprecedented functionality.
