In 1991 he moved to Rome and joined the International Board for Plant Genetic Resources (BPGR; later IPGRI and now Bioversity International), was among others director of the Germplasm Management Unit and from 1998-2006 director of the Genetic Resources Science and Technology Group. Thereafter, as the Genetic Resources Management Advisor he coordinated the global cacao genetic resources network (CacaoNet) and became coordinator of the virtual European genebank system initiative (AEGIS). In January 2012 he formally retired from Bioversity and was offered an Honorary Research Fellowship position. He also continued his AEGIS Coordinator responsibilities, on a consultancy basis.
