Research Interests

Living cells are capable of remarkably sophisticated behavior, combining information from the external environment with an internally stored model of past events to make decisions about how to respond to challenges. These decisions can be thought of as information processing tasks that must occur robustly in the face of various potentially disruptive fluctuations in the conditions inside the cell. Fundamentally, these computations are carried about by networks of proteins and nucleic acids, specialized macromolecular machines sculpted by evolution to channel specific chemical reactions.

We are interested in uncovering the design principles of these networks that allow them to function reliably. We are currently interested in the circadian rhythm, a nonlinear oscillator in living cells that is normally phase locked to the daily rhythms in the external environment and that coordinates cyclic behavior and metabolism in living organisms. We are exploiting a particularly powerful model system from cyanobacteria, where the core oscillator can be studed in a test tube using a mixture of three purified proteins (KaiA, KaiB, and KaiC). Our approach combines methodology from various disciplines including dynamical systems theory, engineering, biochemistry, and quantitative microscopy.
