Professional Summary

I am an AI researcher and engineer working at the intersection of generative modeling, multimodal AI, and controllable visual generation. My research began with visual text intelligence—OCR, handwriting recognition, and mathematical expression recognition—and has evolved toward generative modeling, with recent work on one-shot handwriting generation using diffusion models. Alongside research, I have spent several years building production AI systems at Viettel AI, spanning OCR, eKYC, document processing, and generative data synthesis, which has shaped a research style focused on models that are both novel and practically robust. I am now interested in compositional and controllable generative AI: how generative models can compose multiple constraints at inference time, and how style, content, and structure can be represented modularly through diffusion models, energy-based models, and multimodal representations. My long-term goal is to contribute to generative AI systems that are high-quality, controllable, interpretable, and useful across real-world domains.
