Experience

Chunky Post-training with Seoirse Murray, Sara Price, Collin Burns, John Schulman at MATS

Berkeley, CA2025

  • Framed LLM behavior as mapping input prompts to post-training data chunks.
  • Designed methods to probe decision boundaries between chunks using base models.
  • Assessed consistency in how language models rely on spurious prompt features.
  • Layered Unlearning for Adversarial Relearning with Prof. Dylan Hadfield-Menell at MIT CSAIL

    Cambridge, MA2025

  • Proposed Layered Unlearning (LU) for robustness against adversarial relearning.
  • Designed synthetic experiments and proposed theory to interpret results.
  • Evaluated LU on LLM unlearning benchmarks and showed robustness over existing methods.
