Recent Thoughts

Complex networks and computational neuroscience are apparently independent topics. I don’t intend to emphasize the connection between the two. However, humans’ social networks are prototypical examples of complex networks, and social behavior is generated by the brain. I work on these different topics because of my general interests in social behavior particularly of humans. Understanding social behavior in my own way is my grand challenge. I always have this challenge in mind when I am working on whatever projects.
