Research Interests
I am interested in understanding the dynamics of complex systems with very many degrees of freedom, from both modeling and data perspectives. In particular, I explore questions like:
 what is complex about a complex system?
 how complex is a complex system?
 why is a complex system complex?
 how does a complex system become complex?
To answer these questions, I take a comparative approach to complex systems like:
 financial markets and economies;
 infectious diseases;
 earthquakes and tectonics;
 biological macromolecules;
 brain;
 society and language;
to distill more universal theoretical understanding of such complex systems.
Ultimately, my goal is to develop a computational theory of complex systems, by treating their dynamics as information processing, and discover the underlying logic. In particular, I would like to how understand evolutionary processes geared towards information processing shape the complex network topologies and dynamics of complex systems.
