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

Research interests

Crop breeding and management for sustainable agroecosystems, including multi-actor, collaborative research and innovation in research approaches. Works so far have mainly focused genetically diversified crops and crop species mixtures and their outcomes in terms of weed suppressive ability, yield and resilience in arable systems.
