About me

I am currently an algorithm engineer (2025 - present) in the Language Technology Lab at Alibaba Tongyi Lab, working mainly on multilingualism of multimodal large language models. Before that, I received my master and bachelor degree in Computer Science and Engineering from Shanghai Jiao Tong University (SJTU), under the supervision of Prof. Rui Wang.

I fortunately interned at ByteDance (2024), Microsoft Research Asia (2023 with Dr. Shujie Liu and Long Zhou), and Tencent AI Lab (2021-2023 with Dr. Lemao Liu).

🔬 Research Interest

Large Language Model: Multimodal Large Language Models, Speech Large Language Model, Video Understanding Large Language Model, etc.

Natural Language Processing: Multilingualism, Neural Machine Translation, etc.
