Qualifications

PhD in Biology

I first joined CABI's Swiss centre in 1989. Here, in collaboration with the University of Kiel, I completed my MSc and PhD in arthropod classical biological control. I then completed a post doc from 1996-97 at the University of California, Berkeley, USA. In April 1997, I was appointed as Head of CABI's Swiss Arthropod Biological Control research programme and became responsible for the development and management of several international agricultural classical biological research projects, as well as the supervision of numerous international MSc and PhD students. 


In parallel to this role, I built up the Integrated Crop Management Team at CABI. Today the team comprises a number of consultants across CABI who provide technical support and facilitate activities in various developing, transitional and developed countries to improve agricultural practices. The group uses a multi-stakeholder approach to promote the implementation of ICM, especially the use of biologically-based integrated pest management, as a sustainable agricultural solution. Since 2015, the ICM Team has also been running a Masters of Advanced Studies programme in collaboration with the University of Neuchâtel, Switzerland. 


From 2010-2015, I was the Regional Director, CABI, Switzerland as well as Plantwise Programme Executive. Plantwise is CABI’s first global programme, which works in close partnership with relevant parties to strengthen national plant health systems from within, enabling countries to provide farmers with the knowledge they need to lose less and feed more. 


In 2016, I was appointed as CABI’s Executive Director, Global Operations, responsible for overseeing the management and operations at CABI's 10 locations across Asia, Africa, Europe and the Americas. Within this role, I am also the professional lead for science within CABI worldwide.

Simulation - taking plant health training to the next level

People in developing countries depend on what they can grow and sell so require a lot of plant health knowledge. The CABI-led Plantwise programme delivers plant health advice to farmers. Trained plant doctors diagnose the problems and advise on ways to manage them. Simulations are a new way to deliver...

Providing IPM advice to farmers in Tanzania, Albania and Nicaragua

In Tanzania, Nicaragua and Albania pesticide misuse is a chronic problem in agriculture. Applying pesticides to vegetables just before they are sent to market creates problems. Integrated Pest Management (IPM) aims to rectify this situation. CABI is providing environmentally and economically sustainable IPM...

Strengthening research and knowledge transfer of IPM in Albania

Albania remains underdeveloped and so access to the latest agricultural information (either at farm or academic level) is difficult as government funding is low. This means knowledge on modern and environmentally-friendly approaches is poor. To combat this we want to anchor Integrated Crop Management (ICM)...
