My principal research interests lie in the field of plant-pollinator interactions. The Cape area of South Africa with its spectacular species richness and floral diversity provides a great opportunity to study the role of pollinators in plant reproduction reflecting evolutionary and ecological processes that form biodiversity.

Current research projects
I am currently investigating the role of pollinators in hybridsation at the example of South African Salvia species (Lamiaceae). In the Western Cape two hybrid swarms of three different Salvia species occur: between two bird-pollinated parents and between a bee-pollinated and a bird-pollinated parent. Birds and pollen collecting bees (mainly honeybees) contribute to the breakdown of reproductive isolation.

Furthermore, I am studying the rare phenomenon of small mammal pollination and the characters of plants being adapted to rodents and elephant-shrews. One example is the Pagoda lily Whiteheadia bifolia (Hyacinthaceae) on which I conducted the first observations of nocturnal rodent pollination under natural conditions in South Africa. I also could show that elephant-shrews consume nectar and are pollinators of this plant species.
