Dr Lava Kumar (Chair)

International Institute of Tropical Agriculture (IITA), Nigeria

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.

Prior to joining IITA, he worked from 1999 as a Scientist (Virologist) at the International Crops Research Institute for the Semi-Arid Tropics, Patancerhu, India. There his work mainly focused on viruses diseases of legume crops such as pigeonpea, groundnut and chickpea.

Some of the on-going research projects of Dr Kumar are on epidemiology and management of banana bunchy top disease, viruses of yam and cassava, maize streak and maize lethal necrosis; development of novel virus indexing methods for phytosanitation and virus indexing of vegetatively propagated crops. Controlling insect vector transmitted viruses are among his program priorities.
