I am Group Lead of AI for Transdisciplinary Science (AI4TS) and a Senior Research Scientist at CFAR, A*STAR, Singapore. I received my Ph.D. degree from The Hong Kong Polytechnic University in 2017. My research develops structure-aware and data-efficient learning methods for graph intelligence, foundation models, and AI-enabled scientific discovery.
My research develops structure-aware, data-efficient, and scientifically grounded learning methods for foundation models, graph intelligence, and AI-enabled scientific discovery.
Long-term research themes that define my broader research agenda.
I develop learning methods that incorporate relational, geometric, and structural priors into modern AI systems, with applications in graph learning, sparse computation, and structural attention.
I study data-efficient and structure-aware approaches for adapting foundation models, with interests in federated learning, multimodal reasoning, and scalable representation learning.
I apply machine learning and foundation models to scientific problems in materials, catalysis, biology, weather modelling, and environmental systems.
Current projects that connect methodological research with high-impact applications.
This project develops efficient foundation models and agentic AI workflows for accelerating discovery in surface science and catalysis, integrating multi-fidelity data, sparse learning, inverse design, and experimental validation.
FLASH develops spatiotemporal and multimodal AI methods for dynamic, zone-based lightning risk forecasting and decision support for airport operations.
