The interplay of coupling, gain, loss, and symmetry gives rise to optical phenomena that extend beyond conventional Hermitian descriptions. Among these are exceptional points: degeneracies where eigenvalues and their associated eigenvectors coalesce, producing distinctive wave dynamics and responses to perturbations. These phenomena open new possibilities for understanding and controlling the propagation, scattering, and polarization of light.

Our research examines the physical principles underlying non-Hermitian behavior across diverse photonic systems, with interests spanning exceptional-point topology, modal interactions, and optical sensing. Particular attention is given to how enhanced responses relate to noise, measurement precision, and practical device performance. Connecting fundamental theory with physically realizable platforms guides our exploration of new approaches to light control and sensing.
