My work focuses on the effect of different environmental stressors for marine phytoplankton physiology and ecology. I am thereby mainly interested in the effect of climate change related stressors such as ocean acidification and ocean warming and the effect of trace metals e.g. from volcanic eruptions on marine phytoplankton and the implications for higher trophic levels of the food chain. I also work on biomechanical properties of diatom frustules and how they are affected by environmental conditions.
