Introduction
The Dilemma of Modern Biology
• The amount of data being collected is staggering. Knowingwhat to do with the data is in its infancy.
• The parts list is nearly complete. How the parts worktogether to determine function is essentially unknown.
How can mathematicians help?
• The search for general principles; organizing and describingthe data in more comprehensible ways.
• The search for emergent properties; identifying features of acollection of components that is not a feature of theindividual components that make up the collection.
What can a Mathematician tell a Biologist she doesn’t already know? – p.2/7

Quick Overview of Biology
• The study of biological processes is over many space andtime scales (roughly 1016):
• Space scales: Genes → proteins → networks→ cells→tissues and organs → organism → communities →
ecosystems
• Time scales: protein conformational changes → proteinfolding → action potentials → hormone secretion → proteintranslation → cell cycle → circadian rhythms → humandisease processes → population changes → evolutionaryscale adaptation
Lots! I hope! – p.3/7

Kinds of Math I have Used
• Discrete Math - graph theory, finite state automata,combinatorics
• Linear algebra
• Probability and stochastic processes
• ODE’s, PDE’s, Delay DE’s, Integro-Differential Equations, ...
• Numerical Analysis
• Topology - knots and scrolls, topological invariants
• Algebraic Geometry, Projective geometry
Editorial Comment: Let the biology dictate the math, not the other
way around.
What about Galois Theory? – p.4/7

Some Biological Challenges
• DNA -information content and information processing;
• Proteins - folding, enzyme function;
• Cell - How do cells move, contract, excrete, reproduce,signal, make decisions, regulate energy consumption,differentiate, etc.?
• Multicellularity - organs, tissues, organisms, morphogenesis
• Human physiology - health and medicine, drugs,physiological systems (circulation, immunology, neuralsystems).
• Populations and ecosystems- biodiversity, extinction,invasion

Places Math is Needed
• Moving across spatial and temporal scales - What details toinclude or ignore, understanding emergent behaviors (Thereis no such thing as a homogeneous environment ormedium).
• Understanding stochasticity - Is it noise or is it real?(Periodic behaviors do not exist in biology)
• The challenge of complex systems (e.g., the nature ofrobustness).
• Data handling and data mining - Extracting information andfinding patterns when you don’t know what your are lookingfor.
• Imaging and Visualization (Medical imaging, proteinstructure, etc.)
