2001 - 2006: Undergraduate studies of Biology at Mainz University, Germany. Majors in botany, zoology, and paleontology.  

2006 - 2010: Postgraduate studies at Greifswald University, Germany. My PhD thesis focused on population genetics and reproduction biology of Euphrates poplar (Populus euphratica) under the hyperarid conditions of the Taklimakan desert in Xinjiang, NW China.  

2011: Postdoctoral position within the project “FastWOOD” at Marburg University, Germany. Here, I worked on the development and optimization of molecular tools to identify and characterize poplar clones and varieties for use in short rotation coppices.  

2011 - 2014: Postdoctoral position at Greifswald University. In the course of my project here, we studied the effects of climate change on population genetics and reproduction dynamics of white spruce (Picea glauca) at arctic and alpine treelines in Alaska, USA. This project incorporated molecular markers, dendrochronological tools, and stable isotopes in order to understand how tree populations in these extreme habitats reacted to recent climate change during the 20th century and how ongoing climate change might shape future development of these populations.  

Since 2014: Postdoctoral position at the Thünen-Institute of Forest Genetics, Waldsieversdorf, Germany. My current project focuses on the production of high-quality forest reproductive material, i.e. forest tree seeds that are used to establish new forests or to rejuvenate existing ones. In this project, we study how different management strategies in beech forests affect the genetic composition and constitution of the harvest and, possibly, the adaptability of plants produced from such seeds to changing environmental conditions.

Since 2016 I also participate in the joint project FitForClim, a project that aims to lay the foundation for a sustainable supply of markets with high-quality forest reproductive material (i.e. forest tree seeds) which is able to ensure long term forest productivity under changing environmental conditions.
