Evolution of the nervous system in bilateria
Research in the Developmental Biology Unit is focused on understanding the origin, development, and evolution of organisms and their communities.
Our goal is to explore the rich diversity and complexity of living systems, taking into account their natural context.
Using a highly interdisciplinary approach, we study a wide range of organisms, including collectives of bacteria, unicellular and multicellular eukaryotes. We integrate cutting-edge experimental tools, such as quantitative live imaging, -omics technologies, and functional genetic perturbations. Combined with computational analysis, modelling, and conceptual theory this allows us to address the mechanisms and principles that underlie the complexity of living systems.
Research topics in the unit include:
Living systems are characterised by their ability to respond to internal and external cues with changes in form, function, and/or behaviour. A dynamic balance between plasticity and robustness underpins this responsiveness in the ecological context. To analyse response strategies across temporal and spatial levels of organisation we use and establish model organisms that enable molecular and mechanistic investigations.
For a holistic understanding of living systems, we also focus on the role of time, the temporal coordination (timing), and transitions between developmental processes. A temporal perspective on organisms is critical at multiple scales – development, the organisms’ entire life cycle, and its evolution.
Living systems can only exist as open, far-from-equilibrium processes that consume energy. We need to study how metabolic activities are organised, in time and space, and functionally linked to cellular and developmental programmes for a better understanding of ‘life in context’.
