Research overview

I investigate how virus infection influences interactions of plants with other organisms and plants’ ability to withstand environmental stresses. My research interests include viral subversion of plant resistance, viral gene expression, plant-virus-insect vector interactions, and the effects of virus infection on interactions of plants with beneficial insects such as pollinators. I collaborate extensively on these topics internationally, and particularly with colleagues in sub-Saharan Africa.
