Research interests

My general research interest is to reveal principles of neural computation on the cellular and network level. My lab has especially contributed to advances in the field of in vivo two-photon microscopy for the study of neuronal and glial function in vivo, for example to characterize dendritic Ca2+ signaling in neocortical pyramidal cells in vivo and more recently tp apply genetically-encoded calcium indicators for longitudinal functional imaging studies as well as for imaging neuronal population dynamics in awake, behaving mice. Currently, my lab is further expanding studies of behaviour-related neural dynamics in various brain regions, including hippocampus, using new microscopy concepts, genetically encoded sensors, and optogenetic and chemogenetic tools to monitor and manipulate specific neuronal populations. Our goal is to gain a mechanistic understanding of signal flow on the mesoscale, building a link between local microcircuit operation and large-scale brain dynamics.
