My research focuses on optical waveguide gratings (fiber Bragg and long-period gratings), multimode and interferometric structures, photonic time crystals, and non-Hermitian photonic concepts such as exceptional points to achieve enhanced sensitivity and robustness. A significant part of my work involves mode engineering, dispersion control, and temperature-insensitive sensor design, along with advanced signal demodulation and data-driven techniques for parameter decoupling. More broadly, my interests lie in developing high-performance photonic devices and integrated photonic systems for precision sensing and emerging applications.
