I have more than ten years experience in the biological control of weeds in temperate regions of the world. I have carried out field projects throughout Europe, Turkey and Russia. My main research targets include garlic mustard, perennial pepperweed and dyer’s woad. I am also involved in research on ecosystem impact and management of invasive plant species in Europe, in particular on exotic knotweeds (Fallopia spp.) and have supervised two MSc students.
Japanese knotweed (Fallopia japonica, also known as Reynoutria japonica and Polygonum cuspidatum) and giant knotweed (Fallopia sachalinensis, also known as Reynoutria sachalinensis) are rhizomatous perennial plants native to eastern Asia and were introduced into Europe as ornamental and fodder plants. Today, both species as well as hybrids between ...

Garlic mustard (Alliaria petiolata), is a biennial cruciferous plant of European origin. It is currently invading natural forest communities in 34 states in north-eastern and mid-western USA and four Canadian provinces, and is thought to be causing a decline in native biodiversity.

Dyer's woad, Isatis tinctoria, is of Eurasian origin and was introduced to North America by early colonists as a textile dye crop. Today, it is declared a noxious weed in ten western US states. Dyer's woad does not depend on disturbance to establish and can readily invade and dominate well-vegetated rangeland sites. In 2004, an initiative was start...

Perennial pepperweed (Lepidium latifolium) is a highly invasive mustard that spreads both vegetatively and by seed. It is particularly prevalent in mesic (moderately moist) habitats. Once established, it creates large, monospecific stands that displace native plants and animals and is difficult to remove. Pepperweed is declared noxious or proh...
