January 2003 - December 2007  Friedrich-Alexander-Universität Erlangen-Nürnberg

Januar 2008 - September 2013 Postdoctoral Fellow at the Friedrich-Alexander-Universität Erlangen-Nürnberg (Work on molecular and physiological mechanisms of sugar transport and vascular trafficking in Arabidopsis, Plantago, and sugar beet)

October 2013 - October 2016 Postdoctoral Fellow at the Leibniz Institute of Plant Genetics and Crop Plant Research, Department of Physiology and Cell Biology, Gatersleben, Germany (Studying the molecular and genetic backgrounds of nutrient-efficiency and boron transport in rapeseed)

November 2016 - present Research Associate at the University of Kaiserslautern, Plant Physiology Department

MAJOR RESEARCH INTEREST:

Plant carbohydrate and nutrient transport and the long-distance translocation of both via the phloem from source to sink tissues.

Molecular and physiological responses of crop (sugar beet, rapeseed, cassava) and model plants (Arabidopsis, common plantain) to abiotic stress and nutrient deficiency, with focus on the role of transport proteins during such conditions.
