Research Focus: We focus on mapping brain functions and plasticity in typical development, neurodevelopmental disorders, and treatment with electrical and multimodal imaging (EEG-fMRI, MRS, with S. Brem). Clinical projects cover longitudinal brain mapping in common neurodevelopmental disorders like Attention-Deficit/Hyperactivity Disorder (ADHD), aggression and Dyslexia. We characterize timing, localization and genetics (with E.  Grünblatt) of compromised networks as endophenotypes as state dependent deficits during rest, attention, inhibition, reward processing, or print tuning etc.  For clinical translation we focus on neurofeedback and biofeedback training (with R. Drechsler), and evaluate potential biomarkers using multimodal approaches.

Keywords: ADHD, dyslexia, OCD, conduct disorder, development, plasticity, functional brain mapping, EEG, ERP, fMRI, MRS,  neurofeedback, biofeedback, longitudinal studies, reading, attention, genetics, gene x environment interactions.

Research Focus: Our goal is to understand how blood flow dynamics are regulated in the complex of the brain vascular network in health and disease.

A human brain is powered by ~650km of blood vessels which are compartmentalized into arteries, capillaries, and veins. This immensely complex network can easily fail during disease such as stroke and Alzheimer’s disease. In our projects, we focus on the regulation of blood flow through brain capillaries. Furthermore, we maintain an ongoing effort to develop novel in vitro and in vivo tools to study how to resolve obstructions in large vessels as well as in the microvasculature. We strive to find novel approaches to improve macro and microvascular function in order to keep the brain’s circulatory system functional.

Research Focus: My research team has developed a pioneering application of blood oxygenation-level dependent (BOLD) MRI using precise vasoactive respiratory challenges in order to interrogate brain blood flow control in patients with cerebrovascular ischemic disease and malignant cerebral glioma.

Since 2013, my team has built up a highly interdisciplinary international network, with special focus on cerebrovascular reactivity measurements to determine hemodynamic failure in ischemic stroke patients and to study novel concepts, such as hemodynamic brain tissue responses in chronic ischemia and stroke epiphenomena (e.g. diaschisis). In addition, for malignant cerebral glioma we are currently developing an additional BOLD contrast technique based on hypoxic tissue reactivity in order to investigate respective tissue responses of (peri-)lesional malignant cerebral glioma.

The main goal is to provide new insights in the current pathophysiological concepts of blood flow control in patients with ischemic stroke and malignant cerebral glioma, thereby aiming for clinical integration of this novel advanced BOLD MRI technique for improved therapy evaluation and efficacy.

Research Focus: As a neurosurgeon-scientist my research focuses on the complex pathophysiology of secondary brain injury after hemorrhagic stroke with the aim to develop new diagnostic and therapeutic strategies.

Since 2016, we have established an interdisciplinary scientific network to investigate the toxicity of cell-free hemoglobin in the brain. We were able to define delocalization of hemoglobin from the CSF into cerebrovascular vessel walls and the interstitial space of the brain as the pivotal step for hemoglobin’s toxic effects. Further we could proof the concept of intracerebroventricular haptoglobin treatment to compartmentalize and detoxify hemoglobin within the CSF compartment in translational animal models.

Our current projects focus on bench-to-bedside translation of this knowledge to diagnostic and therapeutic clinical applications.

We are working on several targets including the glutamate receptors, cannabinoid and endocannabinoid systems and ATP Synthase. To characterize the target, murine and post-mortem human tissues will be used to analyze the target in various diseases by qPCR, confocal microscopy and flow cytometry; in vitro autoradiography will be employed to understand the tracer’s specificity and selectivity. Depends on the target, different animal models will be used for in vivo PET imaging. In our GMP lab, several CNS PET ligands are routinely synthesized and applied for drug development and studying brain functions.

Research Focus:  The sheer complexity of neural communication relies on the production and secretion of various neurochemicals. A central question in neuroscience is to understand how precise fluctuations of these molecules relate to behavioral and/or disease states. Yet, technologies capable of addressing this question in living animals with the required spatiotemporal resolution and molecular specificity are largely lacking.

Our Group focuses on developing novel genetically encoded fluorescent sensors based on combined engineering of fluorescent proteins and endogenous receptor molecules (e.g. G-protein coupled receptors) to enable specific and high-resolution optical dissection of neurochemical dynamics in living animals. We aim to combine these molecular tools with state of the art in vivo imaging techniques (fiber photometry, two-photon imaging, optoacoustics) for investigating how neurochemicals orchestrate complex behavioral functions.

Research Focus: Neuroscience has an urgent need for new large-scale neural recording technologies to ensure rapid progress in the understanding of brain function, diagnosis and treatment of neurological disorders. At present, real-time visualization of large-scale neural dynamics is hindered with the existing neuroimaging methods due to lack of capacity for direct imaging of neural activity in large tissue volumes and at high speeds. We develop novel functional neuroimaging tools based on optoacoustics, optical microscopy, ultrasound and magnetic resonance imaging to volumetrically monitor activity of large distributed neuronal populations in whole mammalian brains with unprecedented spatial and temporal resolution.

Research Focus: Myelinating oligodendrocytes and astrocytes are suggested to play an important role in maintaining neuronal functions and long-term integrity. In white matter tracts, axons are almost completely ensheathed by myelin and the axonal compartment may receive metabolic support from surrounding glial cells. Our research focuses on understanding the molecular mechanisms governing neuron-glial interactions and metabolic cooperation. How do myelinating oligodendrocytes and astrocytes sense neuronal activity and how are these signals translated into maintaining neuronal functions in the young and aging brain? Could perturbations in glial metabolic support to axons impact the etiology and pathogenesis of age-related neuropsychiatric and degenerative diseases? To address these questions we combine molecular genetics, electrophysiology, in vivo and ex vivo two-photon imaging, histology, electron microscopy and behavioural studies in various transgenic and knockout mouse models to investigate cellular mechanisms regulating intercellular communication, brain energy homeostasis and cellular integrity.
