Research Overview

The hippocampus is one of the most well characterized and intensely studied regions of the mammalian brain and an ideal model system to test hypotheses linking memory and neural information representation. My laboratory combines in vivo hippocampal electrophysiology and cutting-edge conditional genetics to address research questions at a high level of precision. Our ability to manipulate plasticity, synaptic transmission or neuronal excitability in a subregion or pathway specific manner and to characterize the consequences of those manipulations on the behavioral and physiological level allows us to study the dynamic routing and use of spatial information in the brain.
