I contribute to graduate and undergraduate teaching and student supervision at PhD and MSc level.
Visiting Professor (2016-present), Department of Entomology, Agriculture and Forestry University, Nepal.
My work focuses on devising practical strategies and decision support tools – e.g. ippm.shinyapps.io/server – to enhance the compatibility of IPM (concerning weeds, insects, and disease) and pollination and biocontrol ecosystem services to crops. This work has recently culminated in production of a novel framework for ‘Integrated Pest and Pollinator Management’.
Past research has included the study of 'reward' and 'resistance' traits in crop wild relatives, the effects of crop domestication on nectar/pollen chemistry and pollinator health, and modelling the response of invasive pest plants and functional biodiversity to climate change.
Extension activities include:
1. contributions to advancing IPM systems for Swedish strawberry production, working in conjunction with advisors and growers.
2. consultancy work with UNESCO, UN FAO (Nepal Office), and IUCN for the production of research reports and policy briefs on climate change adaption solutions, particularly for smallholder cropping systems.
