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

Currently, I am responsible for over 60 staff and the running of CABI's UK centre in Egham, as well as strategy and activities for invasive species in Europe and the Americas. 

I started my career at CABI as a casual technician and have since gained comprehensive knowledge and experience in biocontrol programmes including project development, and project delivery. I have also had the opportuntiy to gain practical experience of field entomology, quarantine laboratory studies and have undertaken fieldwork in 18 countries.

I recently managed the Japanese knotweed biocontrol programme for the UK, USA and Canada which has culminated in the first officially-sanctioned release of a weed biocontrol agent in any EU Country.  I also continue to provide strategic leadership for three other biocontrol projects against Water Framework Directive weed targets on behalf of Defra.

My career has involved considerable overseas fieldwork, and coordination of collaborators and supervision of students, and am competent in natural enemy surveys, experimental design & implementation, data collection and analysis, running projects and managing staff and budgets and the eventual production of reports for international and governmental sponsors.

I am regularly invited to speak at national and international conferences on invasives and have served on the organizing committees and chaired sessions at events. I have had considerable interaction with the public and all parts of the media to make CABI's work known to a wider audience and make science accessible. 

I have also trained, supervised and taught up to and including post-graduate level on the Imperial College Pest Management MSc. Course and co-supervision of PhD students.

I am on the EC Working group for the development of the Invasive Species Strategy for Europe and on the editorial board of the journal Neobiota.

Controlling Japanese knotweed in Great Britain

Japanese knotweed is one of the most damaging invasive weeds in the UK, Europe and North America. Growing up to a metre a month, it can push through tarmac and concrete. The cost of control in the UK, if attempted, is estimated at over £1.5 billion. Current control methods rely mainly on chemicals and are...

Finding a biocontrol agent for Crassula

Crassula helmsii is an invasive water weed that dominates still or slow flowing water bodies. It’s spreading throughout the UK and has the potential to out-compete native flora and reduce oxygen levels by forming dense mats. Chemicals are not an option so CABI were commissioned by the UK government to...

Controlling floating pennywort in a safe and sustainable way

Floating pennywort is an invasive aquatic plant that can over-run water bodies in the UK, and is threatening habitats, native plants, fish and insects. Also a problem across much of Europe, this plant has rapid growth and can regenerate from small fragments. Management is mainly limited to mechanical...

Managing invasive rubbervine in Brazil

Invasion by the alien plant rubbervine (devil’s claw) is endangering native flora and fauna in northeastern Brazil. In the Caatinga the endemic Carnauba palm, with its highly valued wax, has come under threat. CABI, in collaboration with Brazilian counterparts, is seeking to evaluate the rust Maravalia...

Establishing a centre for crop health and protection in the UK

Breakthroughs in science and technology are helping overcome global food production challenges and changing the worlds’ agriculture. A new Centre for Applied Crop Science is ensuring the UK has the necessary capital needed to deliver a cutting edge platform to support agriculture in the UK and beyond. CABI...
