Research Interests

I'm broadly interested in spatial cognition, attention, memory, and learning. More specifically, I'm exploring the temporal and spatial dynamics by which different forms of spatial representations, generated in distinct neural structures, are constructed and integrated. To investigate this topic, our lab employs in vivo electrophysiology to record the firing activity of single neurons during the execution of various complex naturalistic behaviors..
