AI systems for evaluation, sustainability, and agentic research workflows.
I am a Research Scientist at Alibaba-NTU Global e-Sustainability CorpLab (ANGEL) and hold a PhD in Computer Science from Nanyang Technological University, Singapore. I build reliable AI systems across LLM evaluation and post-training, agents, recommender and embodied systems, and sustainability—connecting benchmarks, knowledge layers, model adaptation, and research infrastructure to real workflows.
