Research

"Professor Doyle's current research interests are in theoretical foundations for complex networks, primarily in network engineering and biology." He is also "interested in multiscale physics and financial markets, and the interplay between robustness, feedback, control, dynamical systems, computation, communications, and statistical physics." <http://www.cds.caltech.edu/people/> Aug 2008

Prof. Doyle has "applied complex ideas of robust design and control to many fields and is working on a unified theory of control in engineering, physics and biology." <http://www.ieee.org/portal/pages/about/awards/bios/2004controlsystems.html> Aug 2008

Current Projects

• Systems Biology (Fiona Chandra, Genti Buzi)
  • Fundamental constraints and trade-offs of autocatalytic networks.
  • Collaborators: Hana El-Samad, Antonis Papachristodoulou
• Fluids: Turbulence Modeling (Dennice Gayme)
  • Collaborators: Bassam Bamieh
• Physiology (Li Na, Jerry Cruz)
• Internet and Networking (Lijun Chen, Javad Lavaei)
  • Collaborators: Steven Low
• Economics (Jerry Cruz)
  • Market Bubbles and Crashes: We use tools from mathematical finance and stochastic control theory to investigate asset price bubbles and crashes in financial markets. We wish to gain insight using models that account for financial intermediation and associated frictions. Moreover, recent local-martingale characterizations of bubbles may provide avenues into developing new methods of empirical testing for bubbles.
