  • Implemented a quantized integer-arithmetic training library for in-situ drift recovery on HZO FeFET analog hardware, recovering +45pp accuracy on MNIST after 1M cycles.
  • Built CrossSim UI, a full-stack Streamlit diagnostic framework wrapping Sandia National Labs’ CrossSim simulator to characterize analog neural network inference under realistic hardware conditions.
  • Integrated a Gemini LLM agent with function calling, enabling natural language control of simulation pipelines.
