I study what hardware faults do to large language models, and how inference can defend itself. Undergraduate researcher at the TRUE (Trustworthy and Responsible) AI Lab, Oregon State University.

  • Cross-Scale Model Resilience for LLM Inference Under Hardware Faults

    2025

    Manuscript under review Co-author

    Hardware faults (bit flips in GPU memory) can silently corrupt LLM inference. This work studies how that corruption behaves across model scales and proposes a speculative-decoding-based defense: a smaller draft model and the target model cross-check each other. The verification step doubles as a fault detector and corrector.

    My contribution: mitigation implementations and the accuracy / fault-tolerance trade-off analysis, with experiments run on an A100 Slurm HPC cluster.

  • Defending LLM Inference Against Targeted Bit-Flip Attacks

    2026

    In preparation Initial investigation & results

    TRUE (Trustworthy and Responsible) AI Lab, Oregon State University

    Adversarial bit-flip attacks corrupt a handful of carefully chosen weights to degrade or hijack a model while its output still looks plausible. This direction asks when output-level monitoring can catch these attacks, and when it cannot.

    I ran the initial investigation and early results: I designed a draft-model-gated decoding defense and early-warning detection metrics, and benchmarked 7 fault-tolerance defenses against 2 attack classes (stealth and damage) on GSM8K. The work continues at the lab toward publication.

Code for both directions is lab-owned and private until publication.
