Research interests:

Arctic marine biology with special interest in biodiversity, cryo-pelagic coupling and food web studies. Strong background in sea ice fauna and flora, protist and phyto- and zooplankton. Experienced in molecular approaches (HTS, Sanger, TSA FISH, bioinformatics), microscopy, ecological studies and statistics.
