Dear Esteemed Colleagues and Distinguished Guests,

It is with great honor and enthusiasm that I extend a warm invitation to STT51, co-hosted by Faculty of Science, Chulalongkorn University. This year's congress holds special significance as it coincides with several momentous celebrations.

The theme "Collaboration Across Frontiers" embodies our commitment to transcending boundaries in scientific research and innovation. In an era where global challenges necessitate unified solutions, fostering partnerships that span disciplines, cultures, and nations is imperative. STT51 aims to serve as a platform where scientists, researchers, and academicians from around the world can converge to share knowledge, exchange ideas, and forge collaborations that will drive scientific advancement and address pressing global issues.

This conference also provides an opportunity to honor the remarkable contributions of Her Royal Highness Princess Maha Chakri Sirindhorn to science and education, celebrate the enduring friendship and collaborative achievements between Thailand and China over the past five decades, and reflect on the rich history and academic excellence of our Faculty of Science over its 108-year journey. Furthermore, aligning with UNESCO's International Year of Quantum Science and Technology, STT51 will spotlight the transformative impact of quantum research and its potential to revolutionize various scientific domains.

I wholeheartedly invite you to join us in this celebration of science, collaboration, and shared progress. Together, let us transcend frontiers and pave the way for a future where scientific endeavors are boundless and inclusive.

We look forward to welcoming you to STT51 at Chulalongkorn University.

Warm regards,

Professor Pranut Potiyaraj, Ph.D.
Dean, Faculty of Science, Chulalongkorn University
