Research Interests

Understand molecular and neural mechanisms of brain plasticity and behaviors. I was one of the key contributors behind the discoveries of the brain’s navigational system awarded the 2014 Nobel Prize in Physiol or Med to MB and EI Moser. In my own research group, we combine genetic perturbations with imaging and extracellular recordings of behaving animals. We recently showed how a specialized form of extracellular matrix molecules, called perioneuronal nets (PNNs), contribute to regulate adult activity-dependent plasticity and are critical for remote visual fear memories. Combining experimental and computational approaches we also investigate visual information processing in freely moving animals. To facilitate interdisciplinary work, we develop open source tools for meta data handling, storage and data sharing. Heading a project combining human brain activity recordings, patient iPSCs, animal experiments and modelling we link risk gene variants for schizophrenia with neural function.
