CABI, Bakeham Lane, Egham, Surrey, TW209TY, United Kingdom

I started working at CABI in October 2009 in the Invasive Species Management department. I first worked on an economic study into the cost of non-native species to Great Britain, whilst also researching the invasive potential of biofuel feedstock species worldwide and maintaining the CABI Biofuels Information Exchange website.

I continue to be involved in biofuels research and am now also part of the team investigating the potential for biological control of the invasive weed Himalayan balsam. I am also leading the Azolla control project, mass-rearing the weevil, Stenopelmus rufinasus, to be sold to land managers for the biological control of the invasive water weed, Azolla filiculoides.

I have had theoretical and practical training at BSc and MSc levels in various aspects of pest and weed management, and I have a particular interest in biological control.

Azolla control

One of the UK’s most invasive plants, the fairy fern or floating water fern causes problems for anglers and water managers. It forms thick mats on the water’s surface which can double in size in a few days, blocking out light and killing aquatic flora and fish. Fragmentation of the fronds makes control by...

Controlling wild ginger

Plants from the Hedychium genus are widely loved and cultivated as ornamentals but a few are threatening delicate ecosystems in Hawaii, New Zealand, the Macaronesian Archipelago (Azores, Madeira and the Canaries), Brazil, Australia and La Réunion. We are researching natural ways to manage the plants where...

Establishing the psyllid: field studies for the biological control of Japanese knotweed

Japanese knotweed is highly damaging. It spreads extremely quickly, preventing native vegetation from growing and has significant impacts on infrastructure. Current control methods rely mainly on chemicals. Research however has identified a tiny psyllid from Japan as a suitable and safe agent to control...

Unknotting Canada's knotweed problem

Originally from Japan, Japanese knotweed is a fast-growing plant species that is causing a great deal of damage in Europe and North America. This herbaceous plant forms dense, impenetrable thickets and its impacts are varied. Our scientists have already carried out a considerable amount of research in Europe...
