Thierry Vrain長期研究土壤生物學，十年前在分子生物學學系主任職位上退休。他的研究計畫是把抵抗線蟲的基因轉殖到農作物。退休後在園子種東西；五、六年前才真正領悟到土壤生態系是怎樣地運作。此後致力於宣導其理念，因而發現圍繞他身旁有很多人害怕吃到有害身體的食物，而他自己又身懷遺傳工程的技術。他覺得不應該再漠視這些人的需求，因此致力於民間運動，要把近來科學文獻所報告的，可能危害身體健康的內容，拿來教育消費者。

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
