The ability of an organism to measure time is the product of a cellular biological clock. Many phenomena controlled by the biological clock cycle on a daily basis and are called circadian rhythms. My goal is to understand the genetic and biochemical mechanisms by which an organism measures time and uses that temporal information to regulate gene expressionand cellular physiology.
