    Research Area: The Developmental and Interventional Neuroimaging Lab (DINLAB) aims to provide a central point of contact unifying functional and structural neuroimaging studies at the Division of Neuroradiology and Musculoskeletal Radiology. The DINLAB emerges from current and previous cooperations with various labs and groups within and outside of the Medical University of Vienna. The focus of the DINLAB centers on the investigation of the developing healthy, and diseased brain.

Research interests

My research interests include neuroplasticity and treatment-related effects as well as social aspects of chemosensory perception and resting states in particular. Within this endeavor, I try to leverage chemosensory perception as the basis to understand social and cognitive processes associated with olfaction in particular. Throughout the last years, I focused next to basic science on the application of multimodal data registration and analysis methods to various scientific problems within the domain of clinical, social, and cognitive neuroscience. Recently, I got interested in the gut-brain axis and started to work on longitudinal behavioral, functional, and structural brain changes induced by probiotic and symbiotic intervention and their influence on sensory processes, human cognition, and the resting brain. I also try to link advanced functional and structural neuroimaging data with microbiome data obtained through gene sequence analyses and/or high-throughput sequencing to obtain further insight into the bidirectional communication between the gut and the brain.Additionally, I am actively advocating Open Science following Responsible Research & Innovation principles as well as the FAIR principle. As a direct consequence of this, I try to make all my analysis pipelines transparent and reproducible using only freely available open-source products.
