I am a Neuroscientist working at the Charité University Hospital as well as the National Metrology Institute in Berlin, Germany. My research investigates the detailed functionality of neuronal oscillations and neural circuits for perception and neuronal plasticity using brain imaging technologies such as EEG, SQUID-MEG and OPM-MEG with brain copmuter interfaces.
Neural Oscillations orchestrate the transfer and integration of information in the brain, realized by large populations of neurons joining into synchroneous activity. They are crucial for nearly all brain-related processes, such as cognition, perception, memory and sleep. Despite more than 100 years of research on neural oscillations, a lot of questions remain. My goal is to uncover the mechanism underlying neural oscillations and explore the potential of non-invasive brain stimulation for treating oscillatory deficits in neural deseases.

paper alert! Alpha oscillations gate downstream information transfer
For a long time it was thought, that alpha oscillations apply gain control in visual areas, exerting inhibition to incoming sensory information. We challenge this notion, showing that increased alpha inhibition enhances downstream signal transfer with a RIFT (rapid-invisible frequency-tagging) paradigm. A replication using SQUID-MEG and fMRI scans to perform source analysis, confirmed our results.…

paper alert! OPMs outperform EEG and SQUID-MEG in signal-to-noise ratio
Optically pumped magnetometers (OPMs) are a recent technology for magnetoencephalography. While it has many advantages over SQUID-MEG, such as the possibility to adapt to any head shape or to allow for slight movement, it is unclear how well OPMs perform compared to traditional brain imaging methods such as EEG and SQUID-MEG. When playing high-frequency auditory…
