Position

Center for Ecological and Evolutionary Synthesis, Department of Biology, University of Oslo, Oslo, Norway.

Thèmes de recherche

His main scientific interest is to study major transition in history of eukaryotes. He is mainly interested to resolve the evolutionary relationship between major lineages of eukaryotes in order to infer the evolution of cell structures, organelles and genomes. Currently he is exploring the possibilities of using techniques for studying uncultivated eukaryote genomes and transcriptomes and relate the diversity of genes and genomes to the evolutionary history of these enigmatic eukaryote lineages and their ecological adaptations.
