Research focus:

Invasive plants cause negative ecological and/or economic effects on natural, productive and urban systems. In this regard, my research focuses on conducting studies in ecology, taxonomy and genetics of invasive plants, as well as studying their interaction with associated natural antagonists (arthropods and pathogens). These studies allow us to expand the knowledge on the biodiversity, the distribution of species, trophic associations in ecosystems of Argentina and to develop management strategies of the invasive species being studied by using biological control.

I am also interested in the effect of invasions and biological control in a context of global change. I lead a team of researchers focused on the effect of the interactions of herbivores and invasive plants in potential situations of climate change, temperature increase and CO2 concentration. On the other hand, we encourage citizen awareness to generate adaptive management strategies in urban and peri-urban systems, with educational institutions as the link in the communities.

Current research projects:

• Alternanthera philoxeroides, Alligatorweed
• Pontederia crassipes, Water hyacinth
• Solanum elaeagnifolium, Silverleaf nightshade
• Tamarix, Salt Cedar
