About Me

As an environmental scientist, my research interests span broadly across disciplines whilst being mostly centred around biogeochemistry. I am fascinated by the reciprocal interactions between the abiotic world and living organisms. Trying to understand this interplay is a beautiful challenge.


In my PhD project I am applying this interdisciplinary perspective to one of the largest lakes on earth: Lake Tanganyika. Primary productivity in Lake Tanganyika is mostly nitrogen-limited which is unusual for a lake ecosystem. I am interested in finding out how the seasonal and regional differences in lake circulation affect (i) the biogeochemical cycling of nitrogen, (ii) the community of primary producers, and (iii) the migration and feeding strategies of the major pelagic fish species.


Our team is tackling these objectives by a diverse set of measurements – during different seasons and from the North to the very South of Lake Tanganyika. Our analytical toolkit includes wet chemical methods as well as high-resolution sensor applications and isotopic analyses (from nutrients up to fish tissue).
