IntroductionIntroduction

Rita Colwell (NSF): “We're not near the fulfillment of biotechnology's promise. We're just on the cusp of it…”

19th Century Biology: descriptive 20th Century Biology: biochemical 21st Century Biology: quantitative/mathematical Eric Lander (Whitehead Inst): “The 21st Century

Biologist must be, at least in part, a mathematician.”

NSF and NIH are concerned that there are not enough people trained to join hands across the disciplinary boundary between biology and math

Why?Why?

Flooded with data -- need some way to organize it!

Efficiency: mathematical models can do “virtual experiments” faster, more cheaply, and in more difficult conditions than in a wet lab.

Simplifications: mathematics can hide the complexity of a situation behind an organizing concept
