Yang Cao, Virginia Tech (IMAGE) Virginia Tech Caption Cell biologists have developed complex mathematical models of cell-cycle control, but the computer model simulation and analysis has thus far been very time consuming. Cao's research seeks to correct this by developing computational methods and rigorous mathematical theories to integrate the full gamut of continuous, discrete, deterministic and stochastic models.
