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 opportunities 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.

BIO 385 | Junior Seminar

My main research interest is studying mitochondrial genetics using the model animal Caenorhabditis elegans (C. elegans). Mitochondria act as the “powerhouse” of the cell and create the majority of the energy needed for life in eukaryotes. Mitochondria contain their own genome separate from the nuclear genome. Mutations in this mitochondrial genome (mtDNA) are associated with normal aging, common diseases such as diabetes and Parkinsons, and with rare inherited mitochondrial diseases.
Like humans, C. elegans accumulated mtDNA mutations with age and their mitochondria are very similar to human mitochondria in gene content. Previously, I created a large collection of C. elegans worm lines with large deletion mutations in their mtDNA. My research students are characterizing the effects of these mutations on nematode health and fitness.
As a second project, I am investigating local nematode biodiversity. Nematodes (aka “roundworms”) are an incredibly diverse group of animals with over 27,000 species identified and an estimated over 1,000,000 species worldwide. This provides an excellent opportunity for students to discover new species. As part of my Genetics class, I have students go “worm hunting” for nematodes in soil samples. Students isolate, culture and molecularly identify local soil nematodes.
