About me
Hey there! I'm an Assistant Professor at Chulalongkorn University's Physics Department in Thailand. I teach fun stuff like "Physics in Films" and dive into deeper topics like Electromagnetism. I'm part of the Compact Muon Solenoid (CMS) crew, where we explore things like magnetic monopoles and use the CMS detector to seek out four top productions. Besides guiding my students through exciting projects at the Future Circular Collider and diving into machine learning, I also play a role in shaping the next phase of CMS software development. Back home, I take the lead in Thai-CERN research projects. Exciting times ahead!
