Research focus

Interaction of stem cells and their progeny with their microenvironment is critical for regulation of hippocampal neurogenesis. Astrocytes are considered major components of the hippocampal neurogenic niche, but their specific contribution to neurogenesis-dependent plasticity remains largely understudied. In contrast to the prevailing assumption that mature astrocytes are postmitotic in the non-injured adult brain, I recently identified astrocyte subtypes, which started to proliferate in response to pro- or anti-neurogenic stimuli, thus revealing unexpected astrocyte plasticity. In my research I pursue the novel hypothesis that astrocyte heterogeneity and astrogenesis are critical modulators of neurogenesis-dependent plasticity.

Research focus

My research focuses on the identification and functional analysis of novel regulators and modifiers of glial development and myelination in vitro and in vivo. To obtain a better understanding of transcriptional regulatory networks, which jointly work together during glial development to enable proper myelination and remyelination, I focus on potential targets and interactors of known key regulators of myelination processes, such as the transcription factors Sox10 and Myrf in oligodendrocytes.

Research focus

Recent data strongly indicate the influence of the sphingolipid metabolism in the pathophysiology of neuropsychiatric diseases such as depression, alcohol addiction and neurodegeneration. We characterize the involved sphingomyelinase and ceramidase enzymes in various biological materials and investigate their genetic variation, activity and regulation in animal / cell culture models, healthy individuals and patients. Thereby we aim to better understand the underlying molecular mechanisms as well as to evaluate the suitability of these enzymes as diagnostic or prognostic biomarkers and as preventive and therapeutic targets.

Research focus

Motor neuron diseases comprise a heterogeneous group of neurodegenerative diseases leading to progressive disability. Focusing on amyotrophic lateral sclerosis and hereditary spastic paraplegia, I aim to improve the understanding of the molecular basis of these diseases. To this end, I use patient-derived induced pluripotent stem cells (iPS) and the respective derived neuronal subtypes are analyzed on the cellular and molecular level.

Research focus

Myelination and accordingly the development of myelin-forming glial cells is a central process during embryogenesis and regeneration of the nervous system. My research focuses on the transcriptional control of gliogenesis and its modulation by micro-RNAs. Technical approaches include animal models and primary cell culture as well as molecular biochemistry.

Research focus

Sox11 is a member of the group C SOX transcription factor family and is a critical transcriptional regulator of embryonic and adult neurogenesis. It was shown that heterozygous de novo mutations in Sox11 or deletions of Sox11 cause Coffin-Siris syndrome (CSS), a rare monogenic disease characterized by hypoplastic nails, microcephaly, and mental retardation. I am interested in developing and testing genetically engineered in vitro models to understand the role of Sox11 in human neurodevelopmental diseases.
