James E. Ferrell (Jim) (MD and Ph.D. in Chemistry) is a Professor of Chemical and Systems Biology and of Biochemistry at Stanford University. His lab studies the design principles of biochemical switches, timers, and oscillators, especially those that control the cell cycle. We make use of quantitative experimental approaches, modeling, and theory. With a combination of quantitative experimental approaches, computational modeling, and the theory of nonlinear dynamics they aim to understand the circuits that allow cells to make reliable decisions, and how these decisions propagate in both space and time.
