Education

PhD in Biochemistry, Utah State University, Logan, UT in 2001.

Bachelor of Fine Arts in Ballet, University of Utah, Salt Lake City, UT in 1991.

Areas of Research & Specialization

Protein structure - function relationships of metalloenzymes. Studies in her lab focus on the bacterial enzymes of the global nitrogen cycle, the ecology of which can have substantial impacts to both agricultural productivity and water quality. Specifically, she is investigating the mechanism of the Mo-nitrogenase, which catalyzes biological nitrogen fixation (N2 to NH3), and the biosynthesis of nitrous oxide reductase, a copper-containing enzyme which catalyzes the last step of the denitrification pathway (N2O to N2).

Course Information

At Pacific University, all faculty teach a variety of different courses. Typically, we do not use graduate teaching assistants, which means that your classes will be taught by professors and that you will have plenty of opportunites to get to know the faculty in your discipline.

Below I have listed some of the courses that I teach. We are always developing and trying out new classes, so the list may change now and then. You can use the links to the left to read descriptions of the courses listed below.

CHEM 220 General Chemistry I

CHEM 240 Survey of Organic Chemistry

CHEM 380 Biochemistry I

CHEM 480 Biochemistry II

CHEM 481 Biochemistry Laboratory
