Teaching

Environmental Chemistry Lab (BYU, PWS 406, 1 cr)

This one credit course couples various principles of environmental analysis with laboratory experience. Students learn about and perform field sampling, sample preparation, chemical analyses, analytical instrumentation, and data interpretation within the context of environmental research.

Mentored Learning Experience (BYU; PWS 494R; 1-6 cr.)

This course provided undergraduate students with the opportunity to learn sample preparation and laboratory procedures pertinent to environmental research and quality testing. Conducted in the BYU Environmental Analytical Lab.
