We investigate how high-index, topological, and other emerging optical materials can be used to confine and manipulate light at deeply subwavelength scales. Their strong light–matter interactions and material-specific optical properties provide a rich platform for engineering resonant optical phenomena and developing new nanophotonic functionalities.

A central part of our research focuses on dielectric nanoresonators, and metasurfaces, from the response of individual resonators to the collective behavior of large arrays. We study how resonant nanostructures can control absorption, emission, scattering, polarization, phase, and the spatial distribution of electromagnetic fields.

We are particularly interested in high-index dielectric materials and topological insulators, as well as their integration with 2D, quantum, and other functional materials. These systems enable us to explore both fundamental resonant phenomena and new mechanisms for tuning and controlling optical response.

An important direction is the development of active and tunable metasurfaces and resonant optical structures, in which the optical properties can be modified by temperature, phase transitions, strain, electrical control, or other external stimuli. By combining resonator geometry with the intrinsic properties of advanced materials, we aim to develop compact and reconfigurable optical platforms for applications in flat optics, sensing, spectroscopy, imaging, and integrated photonics.
