Message from the chairperson | STT48
Message from the Chairperson
Professor Pranut Potiyaraj, Ph.D.
Chairperson STT48
WELCOME MESSAGE FROM THE CHAIRPERSON OF THE 48TH INTERNATIONAL CONGRESS ON SCIENCE, TECHNOLOGY AND TECHNOLOGY–BASED INNOVATION (STT48)
On behalf of the organizing committee, we look forward to welcoming you to Thailand and to the 48th International Congress on Science, Technology and Technology-based Innovation (STT48) which will be held at Walailak University based in Nakhon Si Thammarat during November 29 – December 1, 2022. Nakhon Si Thammarat, the second largest province in southern Thailand, locates 780 kilometers south of Bangkok along the Gulf of Thailand signified by pristine beaches as well as two national parks.
Since its first launch almost half a century ago as The Congress on Science, Technology and Technology, the congress, organized by The Science Society of Thailand under the Patronage of His Majesty the King, has been one of the long-lasting annual scientific meeting events in Thailand. The congress has recently transformed its name to The International Congress on Science, Technology and Technology-based Innovation to reflect its expanding participants from Thailand and overseas as well as the breadth of its scientific program. This year, the congress is arranged in collaboration with Walailak University.
The International Congress on Science, Technology and Technology-based Innovation (STT) is the largest congress of diversified fields in Science, attended by around one thousand local and oversea participants. The aim of the congress is to bring together Thai and overseas scientists from a wide range of areas in science, technology, and innovation, to provide them the opportunity to present their research work, obtain the update knowledge and exchange experiences. A certain number of researchers from overseas countries will be invited to join this congress.
We are most privileged and honored to have Her Royal Highness Princess Maha Chakri Sirindhorn graciously preside over the Opening Ceremony on November 29, 2022 at 9 am and attend the Keynote Lecture by a world-renowned scientist and the Plenary Lecture from the 2022 Outstanding Scientist of Thailand. During the congress, lectures from several invited speakers, and hundreds of contributed papers from various areas of Science and Technology will be presented orally (onsite or virtual) or in the form of posters. Exhibition on advanced scientific and technological knowledge or instruments/appliances from various organizations and several suppliers will be displayed.
The executive committee, the scientific advisory board, and the organizing committee hope to make STT48 an exciting and memorable scientific event. You will also have the opportunity to visit southern Thailand enriched with cultural and natural attractions.
With the re-connecting world, we would like to welcome everyone back after the difficult time of the pandemic for the three days of scientific content and in-person idea exchanges. We look forward to meeting all of you at STT48.
Professor Pranut Potiyaraj, Ph.D.
