Shaping Sound with Acoustic Metamaterials and Metastructures
We create acoustic structures and metastructures that guide, confine, and block sound in ways not possible with ordinary materials. This research opens new opportunities for compact noise insulation, sound control, and advanced acoustic devices.

Light Trapped Beyond Conventional Limits through Bound States in the Continuum
We study bound states in the continuum, a remarkable class of optical modes that remain strongly confined while coexisting with radiating waves. By harnessing these unusual states, we create ultrahigh quality resonators, efficient nanolasers, nonlinear optical devices, and highly sensitive photonic sensors that push light confinement far beyond conventional limits.

Singular Physics of Exceptional Points and Non Hermitian Systems
We investigate exceptional points and other non Hermitian singularities where waves display striking and counterintuitive behavior. This research explores how gain, loss, and non Hermitian interactions can dramatically reshape light and sound, leading to new concepts for sensing, lasing, topological effects, and wave control in open systems.

Nanophotonics for Future Optical Chips
We develop nanoscale photonic components that generate, guide, and manipulate light on a chip. Our work brings together resonators, waveguides, metasurfaces, and nanoemitters for applications in communications, sensing, and next generation information technologies.

Artificial Intelligence for Next Generation Nanophotonics
We use machine learning and inverse design to discover photonic structures with functionalities beyond standard intuition and trial and error approaches. This direction accelerates the creation of smarter metasurfaces, compact devices, and new paradigms of intelligent photonics.
