For each project, this section documents what limited interpretation more than my modeling ability.

Usually it wasn’t computation or resolution—it was identifiability, measurement averaging, or fabrication uncertainty.

Projects

  • AlN Electroabsorption
    Spatial averaging in UV-Vis prevented depth-resolved mechanism assignment

  • Inverse RCWA
    Parameter degeneracy let to many geometries producing nearly identical spectra

  • g-C₃N₄ Optical
    Structural non-uniqueness, implying multiple doping sites with similar absorption onsets

  • Alloy Sampling
    Finite configuration; sampling ~50 structures from >10⁶ possible

  • Port Metasurface
    Environment non-identifiability can’t separate metasurface gain from channel changes

Constraint types I’ve encountered

[Axiomatic]: Symmetry, conservation laws
[Measurement]: Resolution, SNR, averaging
[Statistical]: Finite sampling, rare events
[Fabrication]: Tolerances, defects, interfaces
[Computational]: Basis sets, functional choice, supercell size

Most projects hit multiple types simultaneously.

How these pages work:

  1. What was measured/computed
  2. What I claimed
  3. Which constraints mattered
  4. What survived vs. what remained ambiguous
  5. What would help resolve it
