Gathering and processing information is fundamental to all life. In cells, this ability is conferred by biochemical networks, collections of genes and proteins that interact with each other and the extracellular environment. Information is detected by proteins at the cell membrane, processed by biochemical networks in the cytosol and nucleus, and then used to decide an appropriate cellular response. Such cellular decision-making is at the core of systems biology and its failure causes disease: whether it is a hijacking of the signalling network by a viral invader, the uncontrolled growth of cancer, or mistimings in the contractions of individual heart cells. The Laboratory of Professor Peter Swain uses a combination of both experiment and theory: microfluidics to generate stochastically changing environments, fluorescence microscopy to quantitatively monitor the responses of individual cells, and techniques from stochastic processes, non-linear dynamics, information theory, statistical inference, and evolutionary biology to develop mathematical models of biochemical information-processing.
