The Digital Nature of Biology

CMSC37701--Math38501, Winter quarter 2007.

This course will explore the digital nature of biology at the molecular scale. We will focus on protein/ligand associations modulated by the hydrophobic effect.

Protein interactions are discrete in nature even though hydrophobic effects are non-specific in general. There is a useful analogy with the duality between the analog and digital nature of computer chips. We refer to this study as the Digital Biology Project. We pursue basic biophysical issues but we also apply our ideas to biomedical problems, e.g., to contribute to the understanding of antibody binding and to drug design.

The course will explore the connections among the following well known but seemingly contradictory facts:

To unravel this seeming contradiction, we explore three other facts about molecular systems: These facts make for the strange world in which proteins struggle for survival in an aqueous environment.

The course will describe the use of datamining to understand the biophysics of proteins, and we will review the derivation of basic models for dielectrics. We will also discuss some changes at the quantum level caused by the large-scale hydrophobic and electronic environment. Implications for protein folding models will be discussed.

No particular background will be assumed. All prerequisites will be provided in the class. We will explore issues in computer science, applied mathematics, physical chemistry and biomedical applications. It is hoped that people from different disciplines will participate.

Notes for the course will be distributed and students will read primary journal articles.

This course is part of the new Ph D program in Biophysics which is now accepting applications.
