Member of the Howard Lee Nanophotonics LabPrincipal Investigator: Professor Ho Wai (Howard) Lee Vertical Cavity Surface Emitting Laser (VCSEL) Sony Project: Collaborated with Sony researchers to use epsilon-near-zero metamaterials and metasurfaces to enhance the functionality of VCSELs. Applied machine learning optimization techniques to optimize the metasurface geometries and materials for enhanced efficiency.Metamaterial Inverse Design with Machine Learning:Built a Residual Neural Network in Pytorch to optimize a metamaterial for broad perfect absorption of light and experimentally characterized its performance. Machine Learning Ellipsometry: Programmed a convolutional neural network in Tensorflow/Keras to analyze the optical properties of materials.Metamaterial Fabrication and Optical Measurement: Fabricated thin film stacks using Atomic Layer Deposition (ALD) and built an optics setup for characterization

Pasadena, California, United States

Metasurface Fabrication: Received training on a variety of measurement and lithography equipment formetasurface fabrication at Caltech

Member of UCLA's Particle Beam Physics LaboratoryPrincipal Investigator: Dr. Pietro MusumeciGraduate Student Mentors: Paul Denham, Eric Cropp, Andrew Fisher, Youna ParkSuper Resolution Ghost Imaging:Wrote MATLAB scripts to generate high-quality cathode maps using computational ghost imaging methods.TESSA 266:TESSA is a highly efficient free electron laser created by using tapered magnets arranged in a helical pattern. I worked on the construction of the undulators, performed simulations of the magnets, and measured/ tuned the undulator's magnetic field profile.Ultrafast Electron Microscopy:Designed and assembled parts of UCLA's PEGASUS beamline as well as performed optic simulations in Python and permanent magnet quadrupoles (PMQ) simulations in Mathematica. Pulsewire Experiment:Measured and recorded oscilloscope readings of an oscillating electrically charged wire threaded through a magnetic lens and analyzed the data in Python to gauge the misalignment of an electron beam.

Principal Investigator: Dr. Franklin DollarGraduate Student Mentor: Matthew Stanfield Self Phase Modulation Dispersion Scans:Built and trained a Convolutional Neural Network (CNN) for analyzing self-phase modulation scans to determine the pulse duration of a femtosecond laser. Programmed a bash script to generate tens of thousands of non-linear physics simulations on UCI's supercomputing cluster, Green Planet, for the training data set.
