Major Research Interests:

The main focus of our research group is the identification of the molecular mechanisms controlling synapse formation, function and stability.

Neuronal circuits are formed through synaptic connections between defined populations of neurons. The regulated assembly and disassembly of synaptic connections ensures precise connectivity during development and during plasticity of the mature circuit. In contrast, the inappropriate loss of synaptic connections leads to a disruption of neuronal circuits and to progressive neurodegenerative disorders. Therefore, identification of the molecular mechanisms controlling synaptic connectivity is essential for our understanding of neuronal circuit function and plasticity in development and disease.

We are combining three complementary systems to gain insights into the principles underlying synapse and neuronal circuit development. We use the Drosophila neuromuscular junction (NMJ) as a model system to identify the molecular and cellular mechanisms controlling synapse formation, function and stability at the level of individual synapses. In addition, we use the adult taste circuit as a complementary model system to unravel how these synaptic mechanisms contribute to the assembly and function of complex neuronal circuits. Finally, we address the relevance of synaptic connectivity and function for learning and memory using olfactory conditioning in the adult fly as an assay.

Together these complementary approaches enable us to identify the cellular principles and mechanisms underlying synapse formation and plasticity with important implications for neuronal circuit function and ultimately animal behavior in development and disease. research pages
