The Dilemma of Modern Biology
• The amount of data being collected is staggering. Knowing
what to do with the data is in its infancy.
• The parts list is nearly complete. How the parts work
together to determine function is essentially unknown.

The Dilemma of Modern Biology
• The amount of data being collected is staggering. Knowing
what to do with the data is in its infancy.
• The parts list is nearly complete. How the parts work
together to determine function is essentially unknown.
How can mathematicians help?
• The search for general principles; organizing and describing
the data in more comprehensible ways.
• The search for emergent properties; identifying features of a
collection of components that is not a feature of the
individual components that make up the collection.

way around.
