Cardiac Nanosignalling

The Soeller Lab at the University of Bern

The Soeller Lab focuses on cardiac physiology while also having a strong interest in optical super-resolution imaging.

Current Openings


We have a number of positions at all levels to fill (postdoc, PhD).

We encourage anybody who is interested to look at the position descriptions. Please contact us for any inquiries.

The Laboratory

Our laboratory is based at the Institute of Physiology at the University of Bern.

We use advanced imaging approaches to address a variety of questions in cardiac physiology. Imaging in general, and fluorescence imaging in particular, is playing an increasingly important role in Biophysics and Biology. Our ability to come up with mechanistic descriptions of physiological processes depends to a large extent on our ability to see the components of a cell, an organism, etc. Our laboratory therefore applies and develops state-of-the-art microscopy methods to improve our understanding of the world around us.

cardiac biophysics


Our work is motivated by the goal to improve our knowledge of the physiology and biophysics of cardiac calcium regulation. Our primary focus is on cardiac ventricular muscle with a unifying theme to elucidate the relationship between nanoscale cell morphology and calcium signalling.

Advanced Imaging

Our understanding of how biological systems work is dependent on the ability to see these systems, ideally with a resolution that approaches subcellular and even molecular scales. This has become possible by rapid advances in fluorescence imaging. The holy grail of advanced imaging is fully quantitative microscopy, that allows us to count molecules in situ, fully spatially resolved, so that we can distinguish different populations, provide molecular statistics, and similar quantitative measures that link form and function. Such quantitative molecular imaging is now becoming a practical reality with the latest imaging modalities.
