Gwen Strand is an instructor in the Biology Department.  She teaches lecture and/or lab for Principles of Biology:  Molecules and Cells, Clinical Microbiology, and Genetics.  She has also taught the first-year seminar course Cancer:  Its Causes and Treatments.

Gwen is the on-campus coordinator for the clinical laboratory science, cytotechnology, and nuclear medicine technology programs with which the department is affiliated.



BIO 243: Microbiology

A basic introduction to the study of microorganisms and the principles of immunology and virology. Laboratory includes the study of basic cell processes and the identification and culturing of typical forms.

BIO 248: Genetics

A study of Mendelian genetics, gene structure, mechanisms of gene expression, mutagenesis, evolutionary genetics, and genomics.

BIO 139: Biology of Cancer

What makes a cancer cell different from a healthy cell? What causes cancer and why can it be difficult to treat? This course will explore the cellular processes involved in the transformation of a healthy cell to a cancer cell. Topics will include common genetic changes, abnormal regulation of the cell cycle, metastasis, and tumor viruses. Diagnosis, treatment, and current news topics will be discussed. Students will complete a research project that focuses on one type of cancer.
