AI systems for evaluation, sustainability, and agentic research workflows.

I am a Research Scientist at Alibaba-NTU Global e-Sustainability CorpLab (ANGEL), with a PhD in Computer Science from Nanyang Technological University, Singapore (CCDS), and a BEng in Electrical and Electronic Engineering from NTU (EEE). I work on LLMs, post-training, AI agents, recommender systems, embodied AI, sustainability and ESG AI, climate adaptation, evaluation, and applied research systems. My work connects benchmarks, knowledge systems, model adaptation, and software infrastructure so AI systems become more reliable, useful, and reproducible in real workflows.
