Molecular Biophysics 621/321. Fall 2003. WF Reed

Guidelines and list of suggested research projects.

Timeline

Sept. 19, 2003: A short (~1 page) proposal of your project is due, describing the general area you have chosen, and what particular aspects you will focus on. You should list at least some references (texts, journal literature, etc.) that you will be using.

October 17, 2003: Short report describing what progress you've made, and what sources you are using.

Late November/First week of December: Class presentations by each student.

December 5, 2003: Final report due.

Format overview

Most students will probably do a literature-based research project, that is, they will find, read, and digest the literature pertinent to their project. The Tulane library and Internet resources are the best aids in such an effort.

In most cases the format will be roughly as follows:

- An introductory statement of the problem or field.

- A summary of theory and techniques behind the problem or field.

This must include a quantitative description of theoretical and/or

experimental principles involved. Your paper should not read like a popular science piece in the New York Times.

- A broad summary of results on the problem or field.

- Some detail on specific results by selected researchers.

- Conclusions, including a summary of the state-of-the art concerning the

problem, future directions, new applications, etc.

Those who wish to do a novel project - e.g. write a computer program for a specific task related to some biophysical/macromolecular problem - will naturally end up doing much less library work. Credit will not be given for reporting directly on results of on-going research for other courses or laboratory rotations. Doing a proper review of topics related to such on-going work, however, may be acceptable. You are encouraged to find and initiate your own project.

Each student will give a presentation at the end of the semester.

 

 

 

Here is a short list of suggestions:
