My main research interests are biology ecology and management of invasive plants. How biological control be combined with other strategies to impact the bionomics of the invasive environmental and crop weeds. We are also studying the phenotypic plasticity and rapid evolution in invasive alien plants. Furthermore, we are interested to study the impacts of climate change on the biology and management of invasive alien plants, of particular interest is how competitive plants and biological control agents respond to the elevated CO₂.
