A major strand of my work involves collaborating with key stakeholders in the online information ecosystem, such as journalists, fact-checkers, and the public, to address mis/disinformation and foster informed public discourse:
- Principles for human-centered NLP fact-checking (Liu et al. 2024, Das et al. 2023)
- AI-assisted multidimensional claim prioritization (Liu et al. 2025)
- Mitigate confirmation bias via LLM-generated multi-persona debate (Shi et al. 2024)
More recently, I have expanded my interests to AI-accelerated scientific discovery, examining how large language models (LLMs) and LLM-based agents may shape research activities (Xu et al. 2025).
In addition, building on my prior work, I continue to investigate service design for older adults’ tech literacy and health (Li et al. 2023, Liu et al. 2022, Liu et al. 2022, An et al. 2025) and information visualization (Colombo et al. 2023, Li et al. 2022).
