Foundation Models Security

Jailbreak defense, adversarial robustness, and internal safeguards for LLMs and multimodal models.

To protect foundation models against adversarial manipulation, jailbreaks, and misuse through principled internal and external defenses.

Overview

This research focuses on the security of large language and multimodal foundation models. Work includes internal neuron-level defenses against jailbreaks, adversarial robustness, and threat detection in AI systems.

Key topics

  • Multimodal jailbreak defense
  • Adversarial robustness for LLMs
  • Internal neuron-level safeguards
  • Threat detection and anomaly analysis
