Founded in 1409, Leipzig University is one of Germany’s largest universities and a leader in research and medical training. With around 30,000 students and more than 5000 members of staff across 14 faculties, it is at the heart of the vibrant and outward-looking city of Leipzig. Leipzig University offers an innovative and international working environment as well as an exciting range of career opportunities in research, teaching, knowledge and technology transfer, infrastructure and administration.

Information processing by the nervous system is based on communication between neurons and their partner cells. While different neuronal communication pathways vary significantly in signalling distance and speed, they also share a common feature: they are adjustable. This important property enables signal transfer to be tuned in an activity-dependent manner and in response to changing physiological demands. The Research Training Group NeuroTune studies molecular mechanisms that modify the way information is transmitted and received by neurons. By investigating different communication pathways, the synergistic goal of this collaborative initiative is to identify general structural and functional plasticity principles and to uncover molecular adaptations specific to species, cell types, and signalling modes.

NeuroTune is a joint initiative of the Faculty of Life Sciences and the Faculty of Medicine at Leipzig University. This collaborative spirit, woven into the fabric of the programme, distinguishes the Research Training Group from traditional pathways to a doctoral degree and provides doctoral researchers from both faculties with an understanding of how basic research and translational research are tightly interconnected.

Within this framework, we offer two PhD positions investigating the molecular and cellular mechanisms of circadian tuning of synaptic communication. Specifically, the projects investigate how neuronal circuits dynamically adjust presynaptic architecture, interneuron coupling and transmitter signalling across the circadian cycle. The project therefore combines neurogenetics, molecular biology, advanced imaging, neuropeptide signalling, adhesion GPCR biology and behavioural neuroscience to understand how neuronal circuits dynamically adapt their communication across the circadian cycle.
