About our research:

We want to unravel how animal multicellularity emerged from our common unicellular ancestor. In order to understand this transition, we study our unicellular phylogenetic-siblings, the holozoans, which hold the key to discerning what we have inherited from our ancestor and what is unique in us. To conduct our research, we use genomics (comparative, functional), cell biology, proteomics and phylogenetics. Given there is no appropriate model organism for studying this transition, we are developing tools to convert these organisms into experimentally tractable model systems.
