Research in our lab focuses on understanding how networks of neurons control complex behavior.  We use animal models to study motivation, learning, and executive function (e.g., decision-making).  We are also interested in neural changes underlying disorders such as addiction, ADHD, obesity, and depression, also using animal models of these diseases. 

We address these questions by monitoring (using electrophysiology and cellular imaging) and manipulating (using optogenetics, chemical genetics, and pharmacology) precisely-defined neural networks.  We also collaborate with computational neuroscientists and statisticians to develop new ways of understanding how neural ensembles are related to behavior.
