Education
2007 - 2013
PhD (Doctor rerum naturalium) in Biology (Ecology) at the Humboldt University, Berlin (grade: magna cum laude). Topic: Interactive effects of nutrients and physical factors on the growth of phytoplankton.
2003 - 2006

Research interests
Topics: Ecology and physics of lakes and reservoirs, particularly the interactions between lake physics, phytoplankton ecology and biogeochemistry. Another core theme is how climate warming, eutrophication, and anthropogenic stressors affect lakes and reservoirs.
Methods: ecological and hydrodynamic modelling, minimal or conceptual models, statistical modelling, laboratory experiments (especially cultivation of phytoplankton), field campaigns and analysis of long-term data.
- Stratification and mixing of lakes
- Light and nutrient limitation of phytoplankton, including physiology and its mathematical description
- Influence of vertical mixing on phytoplankton
- Influence of phytoplankton and water transparency on mixing
- Influence of light pollution on biological interactions
- Oxygen and nutrient dynamics of lakes and reservoirs
- Climate change
