Research
I'm interested in scaling multi-agent approaches to improve downstream task performance and expanding the real-world use cases of agentic workflows, as well as exploring critical areas of LLM safety through interpretability.

code
RepIt isolates concept-specific representations of refusal that can be used to suppress refusal on target concepts while preserving the baseline model’s refusal on other concepts using steering methods in interpretability.
