My role at Kew is Senior Research Leader of Plant Resources. The Plant Resources team investigates the value and use of plant diversity for provisioning humankind with key resources, including food, beverages, timber, fuels, fibres and medicines.

My research background is in taxonomy and systematics but I cover other areas, including climate change, resilience and sustainability. I work mainly on coffee (Coffea) with a regional focus on tropical Africa, Madagascar and Asia.

My main activity for 2015/16 is the project 'Building a climate resilient coffee economy for Ethiopia', which aims to improve the capacity of Ethiopia’s coffee sector to deal with climate change. This is a Strategic Climate Institutions Programme (SCIP) – SCIP Fund – project, backed by governments of the UK (DFID), Norway and Denmark.
