His laboratory is interested in how neural circuits generate sensory perception and behavior. Them use a combination of molecular genetic, in vivo imaging, computational and behavioral approaches to determine fundamental functional properties of neural networks in the mouse olfactory cortex. A central question in neuroscience is how sensory stimuli are detected and processed by neural circuits in the brain to generate sensory perception and behavior. Their laboratory has recently developed new molecular genetic and viral approaches that allow them to target and manipulate defined neural cell types in the olfactory cortex of mice. We have also characterized, using in vivo two-photon microscopy, electrophysiological recordings and computational approaches, fundamental principles of odor information coding in cortical neural networks.
