From sleep/wake cycles to flower openings to cell division and malaria infections, all organisms and cells display rhythmic behaviors. The course will focus on genetic and molecular networks that comprise clocks regulating cell division and circadian rhythms. Quantitative aspects of clock networks will be examined from the perspective of data analysis and dynamical systems models. Class will include lectures, primary literature readings, and in-class projects. Recommended prerequisite: Math 112L or equivalent, and Biology 20, 21, 201L, or 203L.
