I am currently a Visiting Scholar at AI Singapore (through June 2026), supervised by Peerat Limkonchotiwat. I am a Ph.D. student at VISTEC in the Natural Language and Representation Lab (NRL), School of Information Science and Technology (IST), under the supervision of Assoc. Prof. Sarana Nutanong and Asst. Prof. Ekapol Chuangsuwanich.
My research primarily focuses on Multilingual Distillation and Tool-Integrated Reasoning.
Beyond my core research, I serve as a mentor for the SEACrowd 2026 Apprentice Program, collaborating with Samuel Cahyawijaya on Multilingual Agentic Systems for Underrepresented Regions.
Previously, I contributed to the Thai LLM community through the WangchanX Project. My contributions include MT-Bench Thai, a multi-turn benchmark featuring culturally-aligned instructions and a “Knowledge III” category, along with the release of WangchanGLM and the WangchanX Toolkit.

Background
Prior to entering Computer Science, I earned my M.Sc. and B.Sc. (Distinction Program) in Physics at Mahidol University under Asst. Prof. Warit Mitthumsiri, focusing on astroparticle physics. During this time, I held research internships at CERN (CMS) with Kaori Maeshima and the University of Pisa with Francesca Spada. I later transitioned into industry, where I developed my foundations in ML and NLP solving real-world problems with Vipas Sutantayawalee at Backyard.
