PhD studentship in the field of synaptic physiology

Position: Ph.D. Student

Deadline: 18 June 2023

Employment Start Date: 1 July 2023

Contract Length: three years

City: Bonn

Country: Germany

Institution: University of Bonn

Department: Institute of Cellular Neurosciences


A neuroscience PhD studentship in the field of synaptic physiology is available in the laboratory of Prof. Christian Henneberger at the Institute of Cellular Neurosciences (University of Bonn, Germany). The three-year position is part of a larger effort to understand how the precision of information transfer at excitatory synapses is controlled. We will explore how non-neuronal cells determine if glutamatergic synapses are spatially precise or show synaptic crosstalk. Specifically, we will investigate how astrocytes, their structure and their ion signaling modify the spread of the neurotransmitter glutamate in the hippocampal neuropil. This will be achieved by using state-of-the-art optical and electrophysiological methods such as intensity and lifetime based multiphoton fluorescence microscopy of genetically encoded and organic indicators primarily in acute hippocampal brain slices.

The project relies on an extensive experimental toolset for monitoring and manipulating synaptic function, astrocyte structure, extracellular glutamate dynamics and intracellular signalling. In addition, a broad spectrum of imaging approaches and electrophysiological methods is available to dissect the topic further.  Additional information about our research, research methods and recent publications can be found at

The position is available from the 1st of July 2023 on. The contract initially runs for three years. The salary will be according to the German salary scale (65% TV-L E13). The University of Bonn is an equal opportunities employer.


Applicants should have a Master of Science (M.Sc.) or equivalent academic degree in a relevant field of science. In addition, applicants should ideally have experience in some of the mentioned techniques.

How to apply

Applicants should send their application in a single pdf file (max. 5 MB), including motivation letter, CV, scanned academic degrees, list of publications and the contact details of two references.
