Department ‘Ecological Genetics’

Since 2014: Postdoctoral researcher at the Thünen-Institute of Forest Genetics, Germany. My focus is on genetic diversity and genetic structures in forest trees. I investigate how human use affects the genetic diversity in forests and how we can realize a genetically sustainable use and management of our forest resources. In this context, I am interested in how genetic diversity in forests is passed on from one generation to the next and how forest management influences this process.

Genetic diversity is the foundation of all adaptive processes. This knowledge is needed to ensure that our managed forest retain their genetic diversity and their ability to adapt to future environmental changes.

I am further invested in the intensive long-term monitoring of local genetic processes and dynamics (i.e. at the level of individual stands) as well as in the large-scale study of genetic diversity and structure of ecologically and economically important tree species in Germany (i.e. on a nationwide scale).

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.

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.

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.

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