It is my great pleasure to invite you to attend this 15^th International Symposium of the Protein Society of Thailand (PST). Since its foundation in 2006, PST has arranged annual symposia for protein researchers and students to exchange their knowledge, experience and expertise with invited speakers, overseas scientists, senior researchers, and young scientists.

PST also co-hosted conferences with the Asian Oceania Human Proteome Organization in 2014 and the Asia Pacific Protein Association in 2017. James R. K. Cairns and I have also served as President of APPA for 2017 - 2020. All this helps increase the international visibility of protein science in Thailand.

All abstracts and proceedings submitted conferences of the society, including this international symposium, have been critically reviewed prior to oral or poster presentations, and publications. The Organizing Committee also works with companies to arrange booths for the exhibition of equipment and supplies for protein research, as well as to provide Luncheon Lectures.

The Organizing Committee is very grateful to the Chulabhorn Research Institute and Mahidol University, as well as other organizations for their support. I hope that you will accept this invitation to attend this 15^th PST symposium, not only to learn about recent advances in protein research but also enjoy interaction with other protein scientists throughout Thailand.
