I am a geographer and ecologist who studies various aspects of freshwater ecology and biodiversity. Although I study distinct organismal groups, diatoms are definitely closest to my heart. I have been working with diatoms since 2011 and gained a good knowledge on Finnish stream and lake diatom taxa. Part of my job is to participate in improving biological monitoring and assessment methods, mainly regarding diatoms. In addition to macroecological study topics, I am interested in how diatoms respond to anthropogenic stressors through changes in community structures, morphological features and cell contents.
