Research Focus: Our clinical focus is the biopsychosocial evaluation and management of patients suffering from athrogenic, myogenic and neurogenic trigeminal pain disorders. The interdisciplinary team includes dentists, physicians, psychologists and neuroscientists.

We aim at better understanding peripheral and central pathomechanisms underlying these disorders, utilizing primarily functional magnetic resonance imaging and spectroscopy (fMRI and fMRS). We developed several MR-compatible setups for reliable stimulation of extra and intraoral structures.

We are also interested in behavioral aspects of pain. By collecting multicenter clinical data, we analyze potential pain etiologies and modifying factors.

Research Focus: High frequency oscillations (HFO, f > 80 Hz) in intracranial EEG have been shown as a promising biomarker of of the epileptogenic zone. We standardize the detection of clinically relevant HFO in pre-operative and intra-operative invasive EEG to improve surgery outcome. We aim to extend HFO detection to non-invasive scalp EEG, using a low-noise custom-made EEG device. We also investigate epilepsy dynamics and cognitive processing at multiple spatial scales recording EEG and  single unit activity in the mesial temporal lobe.

Research Focus: Our research focus is studying normal and pathological human brain development using non-invasive medical imaging approaches, such as magnetic resonance imaging (MRI) prenatally and in early postnatal life. We aim to understand how common congenital disorders affect brain development, and how these manifest in clinical symptoms. We are interested in utilizing the latest computational image analysis approaches to improve data quality, and to construct models of human development. We also support interdisciplinary clinical research projects that consist of radiologists, neonatologists, neurosurgeons and basic scientists.

Research Focus: Our research aims at developing novel non-invasive imaging techniques for the characterization of preclinical models of brain diseases. A major scientific focus is to elucidate the role of vascular dysfunction, an aberrant coagulation, inflammatory and neurodegenerative processes on brain function in cerebral ischemia and Alzheimer`s disease. To this end, we employ imaging techniques like near-infrared fluorescence imaging and magnetic resonance imaging as well as develop novel molecular imaging probes to generate a variety of target-specific, potentially translatable read-outs. For validation of the imaging marker relevant experimental and genetic mouse models of human disease, pharmacology, biochemical and immunohistochemical techniques will be employed. Since the investigated processes are generic the generated imaging marker might be applicable to a number of brain diseases.

Research Focus: My group’s goal is to address clinical needs through the convergence of engineering, biological and medical research. Within the neuroscience field, we focus on transport processes in the fluid spaces of the brain, namely in the cerebrospinal, interstitial and perivascular fluids. By combining computational techniques with experimental methods, we aim to understand the dynamics of cerebral fluid motion, the driving forces behind these and how they, along with the associated transport processes of metabolites and other substances, are involved in the pathogenesis of CNS disorders

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.

Research Focus: Establish neurophysiological biomarkers to improve the outcome of neurosurgical interventions. We correlate intraoperative measurements with postoperative outcome to optimize the neurophysiological guidance of the surgeon. We analyze data obtained during surgery to investigate the physiological mechanisms involved. For example, high-frequency oscillations (HFO) are a promising new marker for epileptogenic brain tissue in intracranial recordings in epilepsy patients, both before and after resection of the epileptogenic zone.
