Impact Officer for horticulture and natural environment sectors at Scotland’s Plant Health Centre of Expertise.

Sit on the International Plant Sentinel Network (IPSN) Research & Development Committee.

Research focusses primarily on providing evidence for applied solutions to plant health and biosecurity issues for stakeholders in both the horticulture sector, and the natural environment sector. A significant element of this work is investigating effective ways to carry out plant health monitoring and surveillance, including utilising citizen science, so that issues can be identified early and managed quickly.
