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.
