ABOUT
I am a Senior Scientist at IHPC, A*STAR, where I lead Semantic AI for Sustainable and Green Finance Domain. I spearhead strategic innovation initiatives across the department, driving our technological vision and long-term roadmap. With responsibility for identifying emerging technologies and market opportunities, I work with cross-functional teams in developing breakthrough solutions that align with our organizational objectives. My role encompasses fostering a culture of innovation, establishing strategic partnerships, and translating complex technological concepts into actionable strategies. I leverage my expertise in digital transformation to ensure our department remains at the forefront of innovation while delivering measurable business value through carefully orchestrated transformation initiatives. I graduated from Nanyang Technological University with a Ph.D. degree, under the supervision of Dr. Erik Cambria with specialization in Natural Language Understanding and Opinion Mining. I have been working in the field of Natural Language Processing and Opinion Mining for 7 years. My current research interest lies at the intersection of Sustainable and Green Finance, Explainability and Interpretability, and Generative AI. I am enthusiastic about collaboration and eager to offer guidance and support to startups and individuals. Explore my Google Scholar profile for a comprehensive list of my publications. Let's connect and explore the possibilities together!
