COURSE OBJECTIVE

This intermediate-level 3 credit-hour course is focused on the application of physical principles to:

1)
develop quantitative understanding of biophysical processes in natural and engineered macromolecules, membranes, and cells,

2)
learn about modern biophysical methods capturing single molecule properties, and

3)
apply biophysical principles to the solution of biomedical engineering problems.

**General Policy:** All examinations and assignments must be completed in accordance with the University of Utah Student Code. Materials disclosed to the instructor for evaluation must be the original work of the student. Use of material (such as equations, text or graphics) from the web or any other source without proper citation will be considered academic dishonesty.

**Homework Policy: **4 homework assignments will be required. Students are expected to have working knowledge of a mathematical package such as Mathematica, Maple, Matlab or IgorPro and to complete their homework assignments using computer. Presentation in addition to technical content will constitute part of the grade. (Here is an example of what is expected in homework presentations and format). Late homework generally will not be accepted since solutions will be posted shortly after the due date.

**Exam Policy:** 4 open book, open note, 1 hour, written examinations will be given. Three of the exams will be given during the regularly scheduled class time and the fourth exam will be given during the final exam time.
