I am now a final year Ph.D. student in THUIR, Department of Computer Science and Technology in Tsinghua University (THU), Beijing, China. I am fortunate to be supervised by Prof. Shaoping Ma, Prof. Yiqun Liu and Prof. Qingyao Ai. My major research interests include the following three aspects:
Information Retrieval: Traditional and neural approaches for retrieval and reranking.
LLM Applications: Leveraging IR techniques to enhance the capabilities and efficiency of LLMs.
Long-Context LLM: Adapting LLMs to efficiently and effectively handle long inputs and outputs.
I also served as a reviewer/PC-member for SIGIR, ACL, WWW, CIKM, COLING, AAAI, TOIS and etc.

I’m an enthusiast of a diverse array of craft beers, ranging from crisp wheat beers to robust IPAs and everything in between. I’m always on the lookout for exceptional brews from various corners of the globe. Whether it’s the refreshing notes of a Belgian Witbier, the hop-forward complexity of an IPA, or the subtle elegance of a Saison, I relish the opportunity to savor and discover the craftsmanship behind each unique flavor profile!🍻
