Neural Aging Laboratory
Institute of Molecular Biology
University of Innsbruck
We have to account for human aging if we want to understand neurodegenerative diseases.
"We are convinced that patient-derived models are fascinating and useful tools to teach us more about complex human diseases of the brain. In the Neural Aging Lab, we reprogramming human skin cells into brain cells to better understand age-related diseases. We apply both directly induced neurons (iNs) and induced pluripotent stem cell (iPSC) technologies to develop and learn from the next generation of human disease models.
By combining basic cellular neuroscience approaches, precisely targeted cell editing, and a passion for big data biology, the goal of our lab is to identify the molecular key players of human biological aging to enable the development of new treatment strategies for age-related neurodegenerative diseases, including Alzheimer's Disease.“
Jerome is Assistant Professor at the University of Innsbruck in Tyrol, Austria, and Staff Scientist at the Salk Institute in La Jolla, CA. His research focus is to better understand the interface between the biology of aging and neurodegeneration. His patient-centric approach combines human cell reprogramming technologies such as iPSC differentiation, direct neuronal conversion (iN), and 3D culture models with unbiased multi-omics technologies and functional neuroscience. Jerome completed his PhD in the lab of Oliver Brüstle (University of Bonn) and Philipp Koch, and his postdoc in Rusty Gage’s lab.
