Research interests

I work on investigations of dynamic interactions within marine food chains in terms of phytoplankton- zooplankton interactions. This includes experiments on processes affecting phytoplankton populations, for example bloom temporal dynamics. Furthermore, effects of phytoplankton dynamics on reproduction, growth and mortality of key zooplankton species (copepods: A. tonsa) are quantified. Moreover, I’m interested in finding triggers for the production of resting eggs of copepods.
