Work

  • 2022.01 - Present

    Los Angeles, CA, USA

    Graduate Research Assistant
    Levenson-Falk Lab (LFL), University of Southern California
    • Lead developer of SQuADDS, an open-source platform for quantum device design, simulation, and fabrication-readiness; accelerated design iteration from weeks to minutes and adopted across multiple labs.
    • Developed and validated custom high-yield fabrication processes for nanobridge-SQUID resonators (15 nm features), increasing functional device yield from <2% to >90%.
    • Designed and fabricated superconducting circuits including nanobridge-based resonators, offset-charge-sensitive transmons, and custom Josephson parametric amplifiers for probing quasiparticle dynamics and enhancing qubit readout.
    • Engineered full-stack experimental systems, including cryogenic infrastructure (Oxford Instruments, BlueFors), filtering and microwave chains, CPW PCB design, mounting, and advanced packaging techniques.
    • Built automated measurement infrastructure using QUA, Labber, and AlazarTech acquisition systems; integrated parametric sweeps and custom calibration routines across multiple platforms.
    • Created a highly accurate Hidden Markov Model (HMM)-based inference pipeline to extract real-time quasiparticle occupation states from I/Q trajectory data, enabling detailed dynamic modeling of QP trapping and release.
    • Leading experiments on Andreev bound state spectroscopy and nanoSQUID-based QP traps to investigate and mitigate quasiparticle-induced decoherence in superconducting qubits.
    • Extended SQuADDS to support interpretable ML workflows using Kolmogorov-Arnold Networks (KANs) to learn mapping between device geometry and target Hamiltonians.
    • Mentored undergraduate researchers, master's students, and junior PhD students on quantum circuit design, measurement automation, and fabrication processes.
  • 2020.06 - 2020.08

    Nashville, TN, USA

    Summer Research Intern
    Institute for Software Integrated Systems (ISIS), Vanderbilt University
    • Built a full-stack calibration pipeline for microscopic traffic models, addressing parameter identifiability and stochastic noise under multi-objective constraints.
    • Parallelized simulation-optimization workflows using Ray; achieved 10x+ speedup in sweep-based calibration experiments.
    • Designed tools to convert simulation output from the Intelligent Driver Model (IDM) into radar-style datasets for validation against real-world aggregate metrics.
    • Contributed to the Flow RL framework, enabling closed-loop learning in calibrated traffic environments; supported end-to-end tuning and evaluation.
    • Co-authored a peer-reviewed conference paper on microsimulation calibration using aggregate measurements.
    • Supervisors: Daniel Work, PhD. & George Gunter, PhD.
  • 2019.01 - 2020.06

    Lubbock, TX, USA

    Undergraduate Research Assistant
    Texas Tech Multidisciplinary Research in Transportation (TechMRT)
    • Developed an open-source simulator for heterogeneous AV/HV traffic using an extended Nagel-Schreckenberg CA model; supported both rule-based and learning agents.
    • Designed AV control strategies for shared-lane mobility and dynamic lane switching; revealed emergent behaviors like intelligent herding and platoon formation.
    • Integrated reinforcement learning for AVs to adapt to local density gradients; demonstrated benefits in flow stability and throughput in multi-lane networks.
    • Analyzed macro-scale flow metrics derived from microscopic simulation rules; co-authored a journal paper identifying system-wide effects of AV/HV composition.
    • Supervisor: Jia Li, PhD
  • 2018.11 - 2021.08

    Lubbock, TX, USA

    Undergraduate Research Assistant
    Advanced Particle Detector Laboratory (APDL), Texas Tech University
    • Led end-to-end design of optical system upgrades for muon telescopes; developed custom Winston cones that improved signal efficiency from 20% to 78%.
    • Co-designed and assembled both SiPM- and PMT-based muon telescopes; built DAQ systems using Arduino, CAMAC crates, and custom PCBs with wireless synchronization.
    • Wrote real-time data acquisition and analysis software, converting raw readout into muon flux maps; deployed automated pipelines on the university HPC, with cloud-style report generation.
    • Built and validated full Geant4-based Monte Carlo simulation of the experimental system, including physics modeling of photon scattering and muon interactions.
    • Developed a custom ML architecture that inferred photon time-of-propagation to reconstruct 3D tomograms from 2D detector arrays.
    • Actively involved in multiple data-taking campaigns, including first experimental run; maintained 24/7 operations and emergency response support.
    • Presented work at national conferences, winning multiple awards for technical talks and posters on detector design and reconstruction algorithms.
    • Co-authored peer-reviewed publications on both the initial prototype and next-generation telescope design.
    • Supervisors: Shuichi Kunori, PhD. & Nural Akchurin, PhD.
