Portrait of Timothy

Profile

Bridging AI research and adoption.

I help shape applied AI programmes, prototypes, and roadmaps with academic, government, and industry partners. My work spans foundation models, multimodal AI, agents, accelerated computing, and sovereign AI. I did my PhD at SUTD, focused on paraphrasing, semantic similarity, dataset reliability, and sentence-pair classification for NLP generation, classification, and testing.
