Research interests
At the core of my research lies the complex and dynamic connectivity of plants linking them to their environment. I am particularly fascinated by mutualisms between plants and insects and their structural adaptation and reciprocal interaction. Currently, I am working on plants living with mutualistic ants (myrmecophytes) and investigating (a) the intriguing role of fungi as third partner in ant-plant associations, and (b) the sophisticated forms of communication between host plants and their inhabiting ants. The model systems I am focusing on are the Cecropia spp.-Azteca spp. ant-plant mutualism and Piper spp.-Pheidole bicornis system.
Besides ants and plants, the functional aspects of accessory fruit structures are still fascinating to me. Specifically, I address the structural background and radiation processes in several Dipsacaceae groups.
