Professor of Chemistry
Chem 100, Chemistry World
An introduction to chemistry in our society for non-science majors. The course is a hands-on laboratory course based on important and intriguing problems from the world around us. Topics may include forensics, biochemical, environmental, household, medicinal and nuclear chemistry. Modern instruments and analysis will be used to collect and discuss data. Lectures and laboratory. Prerequisite: one year of high school algebra.
Chem 101, Chemistry and Physics of Life
Designed for non-chemistry majors. Chem 101 gives students a condensed foundation of chemistry principles. Lectures and laboratory.
Chem 103, Chemistry and Health
The study of organic and biochemistry, along with applications of biology, health care, and other fields, will be used to understand a public health problem such as malaria. The fundamentals of organic and biochemistry will be learned in the context of reducing infectious agents, protecting people from infection, detecting infections, and pharmaceutical treatments for diseases. A laboratory component will involve chemical experimentation, research skills, experimental design, and communication of results. Collaborative learning will be used in the laboratory. Prerequisite: two semesters of high school chemistry with grades of B- or higher or Chem 101.*
*Taught as a ‘flipped course.’
Chem 200, Analytical Chemistry
Quantitative analysis using traditional and instrumental methods. Lectures and laboratory.
Chem 220, Human Nutrition
A study of the nutritive needs of the body in normal stages of growth and development, food sources of nutrients, nutrient functions, nutrition in clinical practice, and an emphasis on patient teaching.
Chem 303-304, Organic Chemistry*
Covering structure, nomenclature, stereochemistry, and principal reactions for the major functional groups of organic chemistry, this is a one-semester survey course that gives an overview of the field. Laboratory exercises introduce basic purification techniques. Using Chem 303 as a foundation, Chem 304 course presents additional reactions (with an increased emphasis on mechanisms) and material on stereochemistry, as well as introducing spectroscopy (IR, NMR, GC-MS and UV-Vis). Together, the Chem 303-304 sequence covers all topics traditionally covered in two-semester organic chemistry courses. Laboratory experiments teach techniques for organic syntheses, instruments (GC/MS, FT-IR, FT-NMR), and chemical information retrieval.
*Taught as spiral (two-cycle) organic chemistry. For more information, view my presentation given at the Biennial Conference on Chemical Education, August 2018. A spiral organic chemistry sequence, 12 years after implementation.
Chem 430, Biochemistry
Introduction to the chemical processes of living organisms. This course (which complements Biol 307) focuses primarily on proteins (including enzymes) and metabolism, with introductions to carbohydrates, lipids, and cell membranes. Students planning to continue on to graduate programs in medicine, biochemistry, or related fields should take both Chem 430 and Biol 307 to get a solid background in the areas of biochemistry and molecular biology. Lectures and laboratory.
