Current Research:

Ecological interactions of N. attenuata's circadian clock regulation.- The research focus on two aspects, first the interaction of N. attenuata's flowers with its pollinator Manduca sexta and how the clock regulation allows a mechanical and ethological isolation of the floral traits and reproduction mechanisms, using our ecological platform in conjunction with a wind tunnel approach. The second part aims to the effects of an altered clock on the biotic and abiotic interactions under glasshouse and field conditions, to differentiate real clock-related effects from growth conditions.
Chemical characterization of different ecotypes or altered clocks plays an important way to understand their interactions. Flower volatiles profiling as well as nectar composition analysis provides an insight of the pollinator's attraction and reward.
