Description/Objectives

Biophysics involves the application of physical techniques to achieve an understanding of life processes at a molecular level. Physical techniques are central to the measurement of the atomic structure, dynamics and interactions of molecules that are a core foundation of modern molecular biology, while physical theory governs the predicted behavior of biomolecules and helps us achieve a mechanistic understanding of how they work. Thus, biophysics is a central science in the fundamentals of normal physiology, molecular pathology, and in the development of pharmaceutical remedies for a wide range of diseases.

This is the second of two primarily lecture courses that will prepare graduate and advanced undergraduates for research and technical work in Molecular Biophysics. It will cover the practical aspects of the elucidation of macromolecular structure and dynamics by NMR spectroscopy and x-ray crystallography, and the characterization of macromolecular interactions by electron microscopy, mass spectrometry and fluoresence methods. It will examine computational methods for interpreting structure, predicting properties and simulating mechanisms of action.

At the conclusion of this course, students will have a working understanding of the primary experimental and computational methods by which the structure, dynamics and interactions of biomolecules are elucidated and their actions simulated. Students will be able to critically assess primary research literature written for a general scientific audience that uses any of the common physical approaches to understand macromolecular systems. Students will understand the nature of advances that can be made with the principal techniques and their limitations. They will also be prepared for mentored practical research investigations that use the primary methods.
