Academic qualifications

PhD: ‘Increasing crop species and genetic diversity in organic wheat systems to improve weed reduction and yield’ 2014: PhD programme in AgroBioSciences, Scuola Superiore Sant’Anna, Pisa, Italy.

MSc in Agricultural Sciences 2009: University of Pisa, Italy.

Main roles and responsibilities

Managing the Crops programme
