I did my PhD on the restoration of species-rich grassland on ex-arable land, while based at CABI's centre in Switzerland. Also at this centre, I worked on projects on the impact of the Harlequin ladybird in Switzerland. Before starting to work for CABI in the UK, I was a postdoc at Royal Holloway for two years, initially working on mycorrhizal fungi in grassland ecosystems and then on fungal endophytes in creeping thistle. At CABI in Egham (UK), I worked on the monitoring of the release of the psyllid Aphalara itadori, the biological control agent against Japanese knotweed in the UK. I was also involved in a project about the effects of reduced cattle grazing on plants, insects and grassland birds in the UK.


In 2011, I moved to CABI Switzerland and am working on, among other things, the assessment of risks associated with the trade in plants for planting, a major pathway for the introduction of forest pests and diseases.

No policy or measures to avoid their introduction and spread were therefore implemented. Recently, monitoring sentinel plants in exporting countries has been proposed as a valuable tool to...
