Research

We build and support multidisciplinary teams focused on:

Interpretability

Makes the decision-making processes of AI systems transparent and understandable to humans

Robustness

Pertains to the resilience of AI systems facing adversarial attacks or novel environments

Governance

Delves into the frameworks, policies, and regulations guiding AI development and deployment

Current Projects

Jailbreaking vision language models

We examine how fine-tuning Vision-Language Models for downstream tasks increases vulnerability to adversarial attacks and jailbreaking across text-only, image-only, and multimodal attack vectors. We investigate which specific tasks create greater attack surfaces, identify unique failure modes post-fine-tuning, and explore connections between representational drift and adversarial robustness. The work aims to develop alignment steering approaches that can recover robustness without sacrificing task performance.

Investigating the bystander effect in multi-agent systems

We empirically investigate whether LLMs exhibit social psychology phenomena like the bystander effect, conformity, and diffusion of responsibility when deployed in multi-agent scenarios with ethical dimensions. We aim to understand collective dynamics beyond individual LLM behavior, particularly focusing on responsibility attribution and moral judgment failures that could cause harm in high-stakes applications.
