Investigating high-precision optical wave phenomena and structural nanophotonics applications.
Optical Coherence Tomography
Optimizing sub-surface non-invasive diagnostic scanning resolution inside biophotonics structures and cash-crop agricultural cell tissues using advanced SD-OCT signal processing routines.
Diffractive Optics
Modeling, simulation, and micro-mask fabrication of customized diffractive optical elements (DOEs) for custom beam shaping setups and high-contrast light-sheet microscopy engines.
Metaoptics
Engineering planar, sub-wavelength flat dielectric metasurface structures utilizing Silicon Nitride resists to produce aberration corrections for compact microendoscopes.
