Chenyang Lyu, Ph.D.

I am currently a Staff Researcher/Tech Lead at Alibaba Group (ATH), where I lead the Speech and Omni LLM Applied Research team. Previously, I was a researcher at the Mohamed bin Zayed University of Artificial Intelligence (MBZUAI), focusing on multilingual and multimodal large language models. I earned my Ph.D. in Machine Learning from Dublin City University's ML-Labs in 2023, following a Bachelor of Engineering from Northeastern University in China in 2018.

My research spans three main lines: speech and omni models, represented by Marco-Voice for expressive voice cloning and emotional speech synthesis, CVQA for culturally diverse multilingual visual question answering, and GPT4Video for unified video understanding and generation; LLM agents and reliability, including Trust No Tool on agents operating under untrusted tool feedback, Crayotter for traceable long-form video editing, and CoQuIR for quality-aware code retrieval; and multilingual models, including Marco-MoE for efficient sparse multilingual modeling, Marco-LLM for cross-lingual enhancement, and CulturALL for grounded multilingual and multicultural evaluation across 14 languages and 51 regions. My papers have been accepted at top-tier conferences, including NeurIPS, ICML, COLM, ACL, EMNLP, ICASSP, CVPR, and ACM-MM.

My work has received both research and personal recognition. CoQuIR was selected for an ACL 2026 SAC Highlights Award, GPT4Video was nominated for the Best Paper Award at ACM-MM 2024, and I won two championships and two runner-up prizes at the IWSLT 2025 speech translation competition. My open-source projects and contributions have collectively earned 4k+ GitHub stars. I have also received personal honors, including the German DAAD AInet Fellowship, the 2023 Young AI Role Model of the Year award at the Irish AI Awards, and an SFI PhD Scholarship. Individual projects have also received external coverage: CVQA was featured by MBZUAI News, Microsoft Research, and a Microsoft Research podcast; Marco-Voice was covered by Slator; and Marco-LLM was reported by Bloomberg, CNBC, and the South China Morning Post. My broader work and career have also been featured by RTÉ and Irish Tech News, including a podcast interview on LLMs. Before joining Alibaba Group, I held research and visiting positions at Tencent AI Lab, the National Institute of Informatics (NII), and IBM Research-China.
