Introduction of my research

The ultimate goal of my lab is to understand the evolution of animal behavior at the different levels: brain/body anatomy and physiology, and behavioral functions. To achieve the goal, we study crows, highly social birds, as a striking model for the convergent evolution of the sophisticated behavior in comparison to primates by using multidisciplinary approaches (behavioral experiment/observation in the lab and the field station, and physiological and anatomical experiments).
