Research Interests

Our laboratory is interested in the neural mechanisms that underlie courtship display. Much of our current work is focused on studying vocal and non-vocal displays in the brown-headed cowbird (Molothrus ater), a highly gregarious species whose complex social structure is necessary for group cohesion, mating and reproductive success. The work in the laboratory ranges from neural circuits level experiments to computational-based approaches for tracking group behavior. Specifically, we have built a "smart aviary" equipped with an array of computer vision cameras and microphones that allow us to track moment-to-moment behavior of an entire group of songbirds throughout the entire breeding season (see link for story on our aviary). By its nature, our work is highly interdisciplinary and we have close collaborations with several laboratories both. These include the Daniilidis lab (Penn Engineering) where we implement novel computer vision approaches for tracking birds in our “smart aviary”, the Balasubramanian lab (Penn Physics) where we develop novel techniques for quantifying social network dynamics and the Aflatouni lab (Penn Electrical Engineering) where we are developing novel non-invasive wireless neural recording devices for long term tracking of brain activity within our aviary. We also continue our productive collaboration with the White lab (Wilfried Laurier University, Ontario, CA) where we can study the effect of brain circuit manipulations on cowbird social behavior and reproductive success across many years.
