Different Kind of CourseDifferent Kind of Course
First time course offered…an experiment We in the course have very different kinds
of backgrounds Our backgrounds do not prepare us for
the course material Instructor doesn’t know much about the
subject

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
