I am a Post Doc in the project MIXSTRUCT, which as a primary objective aims to decipher the impact bacterivorous phytoflagellates have on the structure of the microbial food web.

In order to achieve this, I work on developing an approach suitable to quantify and identify mixotrophy in controlled laboratory experiments and natural marine microbial communities. Moreover, I am interested on whether elevated organic carbon content as a consequence of increased run-off from land and thwaing permafrost soils, affects mixotrophic organism´s performance and impact.
