Prapit visited us from the Rayong Field Crops Research Center in Rayong, Thailand, as a trainee of IPGRI (now Bioversity International) and the Generation Challenge Program. Within a three-month visit, she not only learnt the techniques, but also analysed most of the nearly 500 cassava samples waiting for her. Prapit came back for another 9 months in 2005 to continue our work in cassava as part of the Generation Challenge Program
