Research focus

In my PhD project I investigate the variability of plant phenology and plant functional traits with a special focus on floral traits. As part of the PhenObs Project I´m mainly working in Botanical Gardens in Germany (Halle, Berlin and Jena). One goal of my project is to examine possible relationships between phenology and floral traits including pollinator resources like nectar and pollen.

Furthermore, I am interested in phenological shifts and the variation of floral traits under future climate conditions. To investigate this, I´m working within a large global change experiment in Bad Lauchstädt, Germany (Global Change Experimental Facility).

As my focus is on floral traits and the quantity and quality of floral resources I am also interested in plant-pollinator interactions and how these are affected by climate warming.
