Research Interests

  • Complex systems: Complex dynamical networks, collective behaviors, nonlinear dynamics, pattern formation, self-organization, multiscale phenomena, social systems, modeling, simulation and visualization of complex systems, complex systems education
  • Artificial life: Self-replication, self-repair, cellular automata, artificial chemistry, swarm behaviors, artificial evolutionary systems, robustness and evolvability of artifacts, application of artificial life to media art
  • Mathematical biology: Theoretical population/evolutionary biology, spatially distributed ecological or evolutionary models, multilevel selection, speciation
  • Computer & information sciences: Automaton and formal languages, computation theory, information theory, parallel computation, nature-inspired computing

Research Projects

  • Pattern formation in self-propelled particle swarms and its application to engineering design
  • Evolutionary perspective on collective decision making, creativity, and innovation
  • Generative network automata and their applications to the modeling and analysis of:
    • Morphogenetic processes of biological/biomimetic networks (Wriggraph)
    • Social networks
    • Network reliability and security
  • Complex systems education with interactive teaching tools
  • Linking youth and community using Information Technology
  • Artificial evolutionary systems built on deterministic cellular automata (evoloop / worms)
