A primary focus of the research in my lab is defining the structure and function of synaptic circuits used to coordinate sensory and motor systems during active vision. We are currently studying circuits of the visual thalamus, pretectum, superior colliculus, and parabigeminal nucleus.. I have over 45 years of experience with synaptic circuit dissection techniques. We routinely use electron microscopy and in vitro electrophysiology, including detailed analyses of synaptic currents and membrane properties and  optogenetic activation of synaptic inputs. We also record brain activity from awake behaving mice, while manipulating circuits using opto- and chemogenetic techniques.
