When handedness becomes an optical variable.
I model chiral silver-nanowire films coupled to dye molecules and connect the electromagnetic modes to circular-dichroism signals measured in the lab.

Computational nanophotonics, plasmonics & metasurfaces.
I build full-wave electromagnetic models of nanoscale optical systems, test them against analytic theory and measured spectra, and use the physics to design devices that control light.

Physics first. Then the device.
The common thread in my work is a simple one: understand the electromagnetic mechanism well enough that the simulation becomes explanatory—not just predictive.

Active & switchable metasurfaces
With phase-change materials such as Sb₂S₃ and VO₂, I design flat optical structures whose resonances—and therefore color, absorption or detection response—can be actively reconfigured.

One-way light at telecom wavelengths
An optical-diode concept for the 1550 nm band that transmits about 88% in one direction and less than 3% in the other, independently checked with RCWA and FDTD.

Selective thermal emission
Nanoantennas that place strong absorption where it is useful while suppressing emission in atmospheric windows used by thermal cameras. One design targets 1.5, 2.3 and 6 μm.

Light-driven chemistry
I contributed electromagnetic modeling to a 2D MXene photocatalyst that uses plasmon-generated hot electrons to drive hydrogen-producing surface reactions under red-light irradiation.

Simulations you can trust
Before a design goes to fabrication, I test mesh convergence and benchmark the electromagnetic solution against analytic theory. I wrote a core–shell Mie solver in MATLAB and automate large FDTD/FEM parameter studies.
