Physics of Complex Systems

My current research is along two lines: evolutionary dynamics (especially cyclic coevolution) and dynamics of neural information processing (especially the role of sleep). Further I have continuing interests on various topics on which I am intermittently active, feel free to contact me if you are interested!
