"It is in my nature to bring things together."


"As an environmental scientist, I want to explore relationships. To do this, it helps that I am not only familiar with biology and ecotoxicology, but also with statistics and modeling. I enjoy the numerics behind nature. That's why I already oriented myself towards quantitative ecology during my biology studies at RWTH Aachen University.
Based on these roots, I have also broadened my horizon towards sustainability topics. A very exciting experience in this context was my work as coordinator of the grassland renaruration project FLIP at RWTH Aachen University. Working at the university offered me another creative task: As a lecturer, I can pass on my knowledge and constantly improve teaching. Consequently, I am now responsible for the courses and training programmes at ToxRat.

Privately, I am also involved sustainability initiatives, for example in an aquaponics project. This is, so to speak, lettuce cultivation in an aquarium, i.e. crops combined with aquaculture. This creative implementation of ecological cycle principles is an example of "bringing things together" that shows: you don't have to instantly reinvent the world - just by combining what already exists, you can create a lot of new things.
This is exactly why I like working at the interface of statistics and biology. With ToxRat, I can apply my passion for linking methods and disciplines in a concrete way, think outside the box on a permanent basis, and moreover creatively implement various ideas for further development."
