Prof. Nicola Spence (Chair)
Nicola is Defra’s Chief Plant Health Officer and is the Head of the National Plant Protection Organisation for the UK. The role of the Chief Plant Health Officer involves advising ministers, industry and others about the risks posed by plant pests and diseases, and ensuring that measures are in place to manage those risks and minimise their impact, as well as leading the operational response in the event of a disease outbreak. Although plant health is a devolved matter; the CPHO co-ordinates the UK response to European and International plant health matters and takes the lead on national plant health emergency response.
Nicola is an experienced research plant pathologist and worked on virus diseases of horticultural crops in the UK and internationally for over 20 years. She is an expert in plant health and international plant trade and was previously the Head of Plant Health and then Chief Scientist at the Food and Environment Research Agency.
She is a Fellow of the Royal Society of Biology, Visiting Professor at Harper Adams University, a member of Court at the University of York and a Trustee of The Yorkshire Arboretum.
She has a BSc in Botany from the University of Durham, an MSc in Microbiology from Birkbeck College, University of London and a PhD in Plant Virology from the University of Birmingham. The subject of her PhD was Bean Common Mosaic Virus in Phaseolus beans in Africa.
She is currently Vice-President of the British Society for Plant Pathology.
Dr. Lava Kumar (Co-Chair)
Dr Lava Kumar is the Head of the Germplasm Health, Virology and Molecular Diagnostics Units at the International Institute of Tropical Agriculture (IITA), Ibadan, Nigeria. He joined IITA in 2007 and his research work is focused on characterization, diagnosis, surveillance and control of plant viruses affecting important food staple crops such as cassava, yam, maize, soybean, cowpea, banana, in sub-Saharan Africa. He is also involved in the production of disease-free planting materials, seed health testing, surveillance of invasive transboundary pathogens, and development of diagnostic tools. Dissemination of knowledge and technology, and capacity development of national program partners through training courses and workshops in plant disease diagnostics and control, are among the key objectives of his program. His research also pioneering ICT-based tools for surveillance and seed quality assurance.
