Biography

I received my Bachelor's degree in Plant Physiology at the University of Potsdam (Germany) in July 2011, and my Master's degree in Plant Physiology at the University of Rostock (Germany) in Sept 2013. Since Jan 2014, I have been a PhD student in Molecular Plant Biology in Academician Prof. Eva-Mari Aro's photosynthesis group. From Jan 2014 - Sept 2017, I had a fellowship in the FP7 Marie Curie ITN "Calcium and light signals in photosynthetic organisms" (Calipso).

Research

My research is focused on calcium signalling events in the filamentous and nitrogen-fixing cyanobacterium Anabaena sp. PCC 7120. We found that calcium is involved in maintaining intracellular carbon:nitrogen balances. A novel calcium-binding protein has been described and may be involved in regulating the carbon:nitrogen balance by controlling light-harvesting in the photosynthetic electron transfer chain or heterocyst formation for nitrogen fixation under nitrogen-limiting conditions.
