Research Interests

My research interests lie in optoelectronic devices, photonic crystals, and nanophotonic structures, with emphasis on the design, modeling, and characterization of photonic crystal–based sensors and integrated optical devices. I work on understanding light–matter interaction, electromagnetic wave propagation, and band-gap engineering in periodic optical media for sensing and communication applications. My research combines theoretical analysis, numerical simulation, and experimental validation to develop efficient photonic architectures. I am also interested in advanced optical materials, nano-structured devices, and emerging applications of photonics that bridge fundamental research with practical optoelectronic systems.
