My main research focus is on the processes that influence the diversity in freshwater plankton populations. As main model system I use Daphnia. We study for example the influence of cyanobacteria on Daphnia populations and their parasites. Recently we sequenced the genome of Daphnia galeata. I see SIL, with its broad representation from countries all over the world, as the ideal organisation to support international collaboration among limnologists. As Swiss SIL representative I want to continue what I do in my work: integrate science and practice. Water is a very valuable good which is under threat even in Switzerland, as witnessed by ongoing discussions on, for instance, micropollutants or whether lakes are now “too clean.” With my contacts within Switzerland and abroad I hope to connect colleagues in such discussions.
