I am a post-doctoral researcher in the Lab of Ute Krämer at the Ruhr-University Bochum. Here, I am using my expertise in comparative genomics, transcriptomics, and repeatomics to investigate heavy metal tolerance in higher plants. My general research interest is the physiology, genetics, and evolution of abiotic stress response in photoautotroph organisms.

In addition, I have a huge interest and knowledge in fitness and bodybuilding. Here, I use my knowledge in muscular physiology and supplement science to educate and consult athletes and fitness enthusiasts.

Research topics and interests

My scientific interest span from the origin of life to the evolution, adaptation 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. Here, I was introduced to the role of transposable elements in genome maintenance and evolution. The work on my PhD thesis was bioinformatics and wet-lab biology as well. To this day, I use my scientific expertise in bioinformatics and wet-lab biology to investigate the trait of heavy-metal accumulation in plants. Our goal is to understand the mechanism, evolution and physiology of this trait and how we can use this to clean metal contaminated soils to avoid toxic metal contaminations in crops, vegetables and fruits.

  • Current research focus: "Comparative analysis of gene expression and regulation among heavy metal and non-heavy metal hyperaccumulators"
  • Previous Research focus: "Evolution and epigenetic regulation of Transposable Elements in Brassicaceae"
  • Ph.D.-thesis: "Repeated evolution of heat responsiveness among Brassicaceae COPIA transposable elements"
  • Diploma thesis: "Natural variation and its constraints: Comparison of chloroplast ascorbate peroxidases in higher plants"

Further Interests

I have a keen interest and huge knowledge in muscular physiological, training and supplement science.. As a dedicated scientist, I like to stay informed and educated in this field by critically reading the newest research articles within this field. I also use my knowledge to educate and consult people in training, nutrition and supplement science to build and remain a strong and healthy body.

Teachings

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.
