CV / Scientific Career


PHD STUDENT at UFZ in the DFG project "Effects of plant diversity and resource availability on plant functional trait variation, plant interactions and community productivity" (Supervisor: PD Fr. Dr. rer. nat. habil. Christiane Roscher)

2004 - 2010

DIPLOMA Biology (Plant Physiology, Geobotany) at Martin-Luther-University Halle-Wittenberg;
Thesis at the Institute of Geobotany (Prof. Dr. rer. nat. habil. H. Bruelheide) "The relationship between distribution boundary and frost hardiness of characteristic woody species of Chinese subtropical forests" (part of DFG FOR891: BEF China SP3)

Forschungsschwerpunkte / Research interests

Plant functional trait variation in response to combinations of different levels in resource availability and biodiversity

- Plant ecophysiology, Stress physiology
- I am also interested in plant distributions/biogeography
