Welcome messages

Dear Esteemed Colleagues, Distinguished Guests, and Participants,

On behalf of the Thai Physics Society and the Organizing Committee, it is my great pleasure to welcome all participants to the 21^st Siam Physics Congress 2026 (SPC2026). This annual conference continues to serve as Thailand’s flagship event for physicists, researchers, and professionals from across disciplines to share knowledge, exchange ideas, and foster collaborations that drive scientific and technological progress.

This year, SPC2026 is proudly co-hosted by Thai Physics Society, Synchrotron Light Research Institute (Public Organization) and Rajamangala University of Technology Isan from 20–22 May 2026, at the Dusit Thani Hua Hin, Phetchaburi, Thailand.

The theme of this year’s conference, “Empowering Physics for Creativity and Sustainability,” reflects our shared belief in the transformative power of physics to inspire innovation, enable interdisciplinary solutions, and promote sustainable development. In a world facing complex challenges, physics stands as a foundation for creativity empowering discoveries that can lead to a more resilient and sustainable future.

The scientific program of SPC2026 has been thoughtfully designed to encompass a broad range of topics in fundamental and applied physics, with particular emphasis on emerging research areas where creativity and sustainability intersect. The conference will feature plenary Keynote and invited talks, as well as oral and poster sessions showcasing contributions from established scientists, young researchers, and students. We hope this event will serve as a dynamic platform for learning, collaboration, and inspiration across generations of physicists.

As the president of Thai Physics Society, I am honored to welcome the physics community to Hua Hin a charming seaside destination known for its natural beauty and warm hospitality. We invite all participants to enjoy both the rich scientific program and the relaxing atmosphere that Hua Hin offers.

I would like to express my sincere appreciation to our organizing team, particularly the Synchrotron Light Research Institute (SLRI) and Rajamangala University of Technology Isan. I would also like to extend my gratitude to our sponsors and partners for their commitment and support in making SPC2026 possible. I am confident that this year’s congress will continue the long-standing tradition of excellence that the Siam Physics Congress has upheld over the years

Once again, welcome to SPC2026. I look forward to meeting you all in Hua Hin and to an inspiring, creative, and memorable conference experience.

Dear Esteemed Colleagues, Distinguished Guests, and Participants,

On behalf of the Organizing Committee, it is both an honor and a privilege to welcome you to the 21^st Siam Physics Congress (SPC2026), which will take place from 20^th to 22^nd May 2026, at the Dusit Thani Hua Hin, Phetchaburi, Thailand. As Chairman of SPC2026 and SPC2026 committees, we are very excited to bring together physicists, researchers, educators, and students from around the world for this premier gathering a platform where collaboration, innovation, and groundbreaking research in physics take center stage.
