Research Interest

Optical Physical Unclonable Functions (PUFs) leverage the intrinsic randomness of nanostructured materials to generate unique, tamper-resistant optical signatures for secure authentication and anti-counterfeiting applications 

Adaptive optical filters control the transmission or reflection of specific wavelengths of light through engineered nanostructures, enabling precise color tuning, spectral selection, and advanced photonic device functionality, with applications spanning computer vision, sensing, imaging, and display technologies. 

Functional plasmonic metasurfaces manipulate light at the nanoscale through engineered resonances, enabling enhanced performance in sensing, imaging, spectroscopy, and other photonic applications.
