I am a Ph.D. student in the Natural Language Processing and Representation Learning Lab (NRL) at VISTEC, Thailand, supervised by Assoc. Prof. Sarana Nutanong and co-advised by Assoc. Prof. Attapol Rutherford.
Ph.D. Thesis: Resource-Constrained Named Entity Recognition. My research focuses on developing NER systems under limited-resource settings. I contributed a Thai fine-grained nested NER dataset and a bilingual (Thai–English) financial NER dataset, analyzed the generalization of encoder-based and large language model (LLM)-based NER methods to unseen entity types and domains, and studied the robustness of multilingual text normalization in informal and noisy text.
Currently, I am working on LLM-based retrieval-augmented generation (RAG) systems for the medical domain. My work involves supervised fine-tuning (SFT) and preference optimization methods (e.g., DPO, GRPO) for multi-turn medical question answering, as part of the ThaiLLM project.
