My research has primarily focused on the theory of quantum materials, particularly rare-earth-based systems for unconventional and frustrated magnetism. I have explored single-ion anisotropy, crystal field effects, and thermomagnetic properties in rare-earth systems such as garnets (Tb₃Ga₅O₁₂ and Tb₃Fe₅O₁₂) and pyrochlores (Ho₂Ti₂O₇, Dy₂Ti₂O₇, and Pr₂Sn₂O₇). My contributions include studying the timescales of emergent 'monopoles' in classical and quantum spin-ices, investigating the role of non-collinear single-ion anisotropies in spin-wave models for iron-based rare-earth garnets, and supervising studies on one-dimensional models exhibiting phase-transition-like thermodynamic signatures. My work also involves strong collaborations with experimentalists, particularly in inelastic neutron scattering and synchrotron X-ray experiments on magnetic quantum materials.

At the University of Catania, my research is expanding into plasmonic excitations in quantum materials (Modelling quantum material nanostructures for innovative plasmon-based approaches). Working with Francesco M. D. Pellegrino, I am studying plasmonic phenomena in topological materials, particularly in systems where spin-orbit coupling (SOC), strain, and Berry curvature influence collective electronic excitations. This new direction connects with my expertise in correlation effects and symmetry analysis, while introducing me to research about electronic transport, plasmonic response, and optoelectronics in 2D topological materials. As part of this research, I familiarised myself with electromagnetic wave propagation in inhomogeneous media and the physics of Weyl-semimetals waveguides, particularly plasmonic effects at the Weyl-air interface.
