I work in the Group for Genetic and Epigenetic evolution at Max Planck Institute for Plant Breeding Research under the supervision of Ales Pecinka. My research is focused on the genetic and molecular evolution of transposable elements ("mobile" repetitive DNA elemts) in Brassicaceae species under ambient and challenging conditions.

The evolution, stability and maintenance genomes in photoautotroph organisms is one of my mayor research interests. This includes impact on and by coding, as well as non-coding DNA regions and elements driven by environmental changes.

Research topics and interests

My main scientific interests spans from the origin of life to the evolution and natural variation of photoautotroph organisms. This led me to do my PhD on a topic regarding genome and epigenome evolution under ambient and challenging conditions. With this, I was introduced into the role of transposable elements in genome maintenance and evolution. During my two years I got more and more interested about TEs, including their function, evolution and influence on genome stability and evolution.

Beside that, I am interested in muscular physiology and metabolism. This includes also interest in the molecular biology and physiology of muscular and metabolic disease.Further, I like to understand the function (molecular and physiological) of steroids, supplements and drugs. Thereby, I wanna know how abuse of these can lead to muscular and metabolic dysfunction (most likely by organ insufficiency).

It is and was always a pleasure for me to teach young students. During my studies I have had numerous possibilities to do so and getting experience. In my opinion, it is always necessary to do science and also teach new students in theory and practice.
