We are a group of neuroscientists, physicists, biologists and engineers who develop and apply new optical techniques with the goal to study brain-wide neuronal circuits at unprecedented depth and scale. The lab is part of the NeuroCure Cluster of the German Excellence Initiative and is located on the Charité / Humboldt University campus in the centre of Berlin.

If all our bodies were as transparent as these jellyfish, the implications for biomedical science would be tremendous. Biologists could directly look at deep tissues to study their function and doctors could diagnose diseases such as cancer by direct observation.
Yet, when light propagates through most biological tissues, refractive index inhomogeneities cause diffuse scattering that increases with depth. This poses a major challenge to optical techniques, fundamentally limiting their biomedical usefulness to thin sections or cultured cells in vitro and superficial layers of tissue in vivo. As a result, despite many breakthroughs enabled by advances in optical imaging and optogenetics, these techniques are still severely handicapped by scattering.
The goal of our research is to address this challenge by developing new optical techniques based on wavefront engineering and optical time reversal. These approaches, in combination with functional imaging and electrophysiology, will enable us to study circuits of the brain that have thus far been inaccessible to noninvasive optical methods.
