Jean Christophe Glaszmann initially focused on plant breeding and ecological genetics, significantly influencing rice variety classification at the International Rice Research Institute (IRRI) and advancing sugarcane genetics through genome studies. After spending five years at IRRI (1982-1987), he returned to Montpellier, achieving his HDR in 1993. He served on the Board of Directors at Cirad from 2007 to 2010 and directed AGAP, a research unit on plant genetic improvement, from 2010 to 2014. He also led a sub-program on crop genetic diversity for the CGIAR Generation Challenge Programme from 2004 to 2010. In recognition of his contributions, he received the Prix Jean Dufrenoy from the French Academy of Agriculture in 2008.
