      • Worked on the LMI-SOM (light matter interaction in structured optical materials) team developing the MANTIS framework (machine accelerated nanoscale-targeted inhomogeneous structures) using high performance computing (HPC) • Used waveguide/metasurface modal decomposition to restrict parameter space searches to regions of interest, decreasing optimization times by a factor of two • Created artificial neural networks (ANN) to discover an angle and polarization independent active switchable metasurface mirror with speeds roughly a million times faster than using conventional CEM techniques (device spec: 95% reflectance and >80% transmittance between phase states) • Ran particle swarm optimization (PSO) to find durable and scalable/manufacturable broadband metasurface reflectors with >99% reflectance over >310 nm bandwidth at telecommunication wavelengths • Collected, cleaned, cataloged, and analyzed multivariable data sets (tens of thousands of files with millions of entries) with various structures and file formats (csv, txt, json, hdf5, npy, tar, zip, gzip) Show less

      1. Studied organic thin film fluorescence to create more efficient organic light emitting diodes:• Used molecular beam deposition to grow organic semiconductor thin films• Used high-powered ultrafast-pulsed Ti:sapphire laser to study exciton dynamics in thin films by using time-integrated and time-resolved photoluminescence• Modeled quantum mechanical singlet/triplet exciton lifetimes through coupled differential equations with Mathematica software2. Developed and studied various waveguides for photonic and optoelectronic devices:• Modeled, developed, fabricated, and experimentally tested organic multilayer waveguides that had phase matched transverse electric and magnetic mode polarizations• Modeled, developed, and experimentally tested magneto-optical waveguides that underwent mode conversion via Faraday Effect (active optical mode switch)• Modeled long-range surface plasmon polaritons in hybrid multilayer waveguides3. Developed new non-invasive technique to image depth-resolved microscopic objects through turbid media in real time:• Performed time-integrated photoluminescence measurements on quantum wells (QW) to study exciton population decay• Performed four-wave mixing on quantum wells to study exciton decoherence in QWs• Performed optical coherence imaging and contrast-enhanced holographic imaging of microscopic objects by recording hologram onto phase-coherent photorefractive QWs• Used near-field Fresnel diffraction to model holographic images recorded by QWs and read by a CCD camera Show less

    • Teacher Assistant
      • Aug 2011 - May 2018

      Included instructing and grading in-glass work and reports/homework for physics labs and small study group recitations (including algebra and calculus based first year physics, as well as second year intermediate physics). Also, I worked as a TA for large classes that followed a flipped-classroom format.
