As AI becomes embedded everywhere in everyday life, I study how intelligent systems can act safely, protect privacy, and remain reliable over long horizons. My research spans multi-turn attacks, timely defenses, and state-aware safety for tool-using agents; privacy in physical and interactive environments; and the evaluation and training of long-horizon agents. These directions come together in the research initiative Everywhere Safety.

Agent post-training, safety, privacy, and retrieval

Generate diverse, stateful agentic RL environments with verifiable rewards by deriving both dynamics and evaluation from solved mechanisms.

Introduce CKA-Agent, a framework that reformulates jailbreaking as an adaptive tree search over the target LLM’s correlated knowledge, achieving 96-99% attack success rates against state-of-the-art commercial LLMs.

A comprehensive evaluation benchmark for assessing privacy awareness of large language models in physical environments, revealing significant gaps when privacy is grounded in real-world contexts across four evaluation tiers.

With increasing demands for efficiency, information retrieval has developed a branch of sparse retrieval, further advancing towards inference-free retrieval where the documents are encoded during indexing time and there is no model-inference for queries. Existing sparse retrieval models rely on FLOPS regularization for sparsification, while this mechanism was originally designed for Siamese encoders, it is considered to be suboptimal in inference-free scenarios which is asymmetric. Previous attempts to adapt FLOPS for inference-free scenarios have been limited to rule-based methods, leaving the potential of sparsification approaches for inference-free retrieval models largely unexplored. In this paper, we explore ℓ0 inspired sparsification manner for inference-free retrievers. Through comprehensive out-of-domain evaluation on the BEIR benchmark, our method achieves state-of-the-art performance among inference-free sparse retrieval models and is comparable to leading Siamese sparse retrieval models. Furthermore, we provide insights into the trade-off between retrieval effectiveness and computational efficiency, demonstrating practical value for real-world applications.
