In a collaborative effort, David Ainley (penguin ecologist, USA), Grant Ballard (penguin ecologist, USA), Stacey Kim (marine ecologist, USA), Jennifer Burns (seal ecologist, USA) Melanie Massaro (avian ecologist, Australia), Joseph Levy (permafrost geologist, USA), William Davison (fish physiologist, New Zealand) and we are exploring the diversity of viral communities in the Antarctic.

Darren Martin (author of the most widely used recombination detection software RDP; South Africa) and I have set up a wide collaborative network of scientists world-wide to study viral evolution though recombination, viral phylogeography and global viral movement patterns of the plant-infecting geminiviruses and nanoviruses. While initially our research was based in Africa and South America, recently we have also focused on the Pacific region. As a team, Philippe Roumagnac, Pierre Lefeuvre, Darren Martin and I are attempting to identify drivers of plant viral emergence in ecosystems.


In collaboration with various scientists around the world, we are unraveling the viral diversity in arthropod  viromes in various ecosystems.

We have an active avian circoviurs disease research program with the Department of Conservation of New Zealand, Parc Zoologique et Forestier (New Caledonia), Bethany Jackson (Murdoch University, Australia), Tomasz Stenzel (University of Warmia and Mazury, Poland) and Tomasz Piasecki (Wrocław University of Environmental and Life Sciences, Poland).
