Scientific interests in a nutshell:
My main research interests lie in plastic and adaptive responses to climate change by calcifying and non-calcifying algal species that live at the margins of their distribution. In calcifying algae, I study how, during the process of biomineralization, the distribution of magnesium and trace elements are modified by climate change and how this in turn affects the structural integrity of the thallus. The main research activities are conducted through experimental ecological studies, conducted in the field and in a controlled environment.
