About
I am a PhD student in the CLAN Lab, Department of Computer Science at Aarhus University, Denmark, under the supervision of Akhil Arora. I am also affiliated with the Danish Pioneer Centre for AI (P1).
Prior to this, I obtained a Master degree in Computer Science from the University of Copenhagen, advised by Daniel Hershcovich and Maria Maistro. I was a visiting student at National Taiwan University, Taiwan in 2024 and a Researcher & Developer in Baidu Search during 2018-2022, and I received my BSc in Software Engineering at Dalian University of Technology, China in 2019.
My current research focuses on Human-Centric and Trustworthy NLP, including Human–AI co-evolution and the development of inclusive NLP for underrepresented communities. To achieve this, my work broadly spans areas such as RAG, memory, reasoning, and agents.
I would be happy to explore opportunities for collaboration and supervising student theses/projects. Please feel free to email me to stay in touch.
