About
Hello, thank you for visiting my site! 👋
I am a third-year Ph.D. candidate (doctoral researcher) funded by the European Research Council, affiliated with the project: Individualized Interaction in Discourse, led by Prof. Dr. Vera Demberg at Saarland Informatics Campus, Saarland University. I was a visiting Ph.D. student at the University of Edinburgh from February 2024 to August 2024, working under the guidance of Prof. Dr. Mirella Lapata. To contribute to the NLP community, I joined the ACL Rolling Review Team as a technical support member, primarily responsible for ARR website updates. Prior to my Ph.D. studies, I earned a Master’s degree in Computer Science at the University of Amsterdam, under the supervision of Prof. Dr. Khalil Sima'an at the Institute for Logic, Language and Computation (ILLC).
My Ph.D. research is devoted to abstractive summarization, with a consistent focus on discourse-driven and planning-based approaches. I have constructed two large-scale resources to support this line of work: a long lay summarization dataset (LREC-COLING 2024) and a scientific video-to-text dataset (ACL 2025). Methodologically, I have investigated discourse-aware modeling by integrating discourse uncertainty into LLMs (ACL 2023, NAACL 2024), and designed discourse-driven planning techniques for structured summary generation (ACL 2025, TACL 2025). These two core directions—discourse modeling and content planning—are brought together in my TACL 2025 study, which represents a sustained and in-depth effort to improve the faithfulness and interpretability of summarization process.

More about me:
- I was born in the southernmost city in China: Sanya.
- Originating from a peasant family, my parents ventured to Sanya City as migrant workers. Throughout my upbringing, they have showered me with immeasurable love, for which I will forever remain deeply grateful.
- Over time, I came to understand the complexities of life and the fact that not everything is black and white. This realization led me to make peace with myself and cultivate a more open-minded perspective.
Life pursuit:
I have long aspired to make a meaningful contribution to society, dreaming of a research or work that could positively impact many people around the world.
