About me :

Currently serving as an Assistant Professor at the Department of Physics within the Faculty of Science at Chulalongkorn University, Thailand. My research pursuits primarily lie in collaboration with the Compact Muon Solenoid (CMS), exploring diverse research topics. These include searching for magnetic monopoles, searching for four top productions using the CMS detector. I also supervise students on searching for new physics at Future Circular Collider, and applying machine learning to CMS Data Quality Monitoring and flash simulation. My role at CMS is to convening Phase-2 software development as part of the Offline and Computing coordination area. As for research management in Thailand, I am the principal investigator (PI) for Thai-CERN research proposals for the funding agency, the Program Management Unit for Human Resources and Institutional Development, Research and Innovation.

The selected list here, I include only journal papers which I am an author or where I was involved during the very intensive peer review inside the CMS collaboration. I do not include any journal papers created because I am a member of CMS Collaboration.
