I work in Cornwallis group here at the department of biology. My PhD program deals with ecological factors affecting the transition between uni- and multicellularity. We use freshwater green algae system to study this question. We created a database to identify ecological correlates on the presence and abundance of multicellular algae in Swedish lakes; we also do comparative experiments to better understand the role of macronutrients on the coexistence of multicellular and unicellular algae. Future plans include studying the developmental bases of multicellular life cycle and the role of sexual reproduction in the evolution of multicellularity.
