Using transgenic mouse lines and viral-vector induced loss-of-function manipulations, we investigate the effect of serotonin signaling on impulsive behavior and the underlying neural circuits.  

Our lab is focused on the careful analysis of behavior in rodent models.  We use instrumental behavior paradigms to measure a number of different facets of impulsive and reward-related behavior.   

Using state-of-the-art technology, we can visualize the activity of large populations of neurons at the single-cell level as well as the serotonin levels, in awake behaving mice. We use miniature microendoscopes and fiber photometry to view fluorescence emitted from biosensors.
