That Chomchuen is a research assistant at NARIT (since March 2025), developing software for astronomical photometry and spectroscopy: Python- and .NET-based control of CCD and CMOS cameras, plate solving and star tracking, and the observing software for the team's instruments. He holds a BSc in Statistics (first-class honors, 2021) from Chiang Mai University, where he is now an MSc student in Computer Science.

He is first author of the SPIE 2026 paper on the unified software architecture for real-time autoguiding and robotization of the LRS and CoLoRS spectrographs at the TRT and TNT.
