Sara Tolsma '84 Professor of Biology
Ph.D., Northwestern University
B.A., Northwestern College (Iowa)
VPH 109 B
Dr. Tolsma’s research efforts in cancer genetics and cell biology have been widely published in scientific journals and have received a number of awards. A Northwestern College alumna, she holds a doctorate in microbiology/immunology/virology from Northwestern University. During a sabbatical, she worked on a cell and molecular genetics textbook for non-science majors, as well as an adult Sunday school curriculum on genetic technologies. She has been a part of several symposia on bioethical issues surrounding genetic technologies, such as stem cells, cloning and genetic testing. Her current laboratory research extends her interest in genetics to populations in a study of mayfly genetic variation in Northwest Iowa watersheds and her interest in cancer cell biology with a project that measures the anti-proliferative effects of plant extracts and chemicals in those extracts on human tumor cells in vitro. The 2015 recipient of Northwestern's annual Teaching Excellence Award, she was appointed to the Northwestern College Endowed Professorship in 2016.
- Introduction to the Life Sciences
(IGE option under Science and the Natural World) This course will explore life processes common to plants, animals, andprotists; cell structure and function; biodiversity; an introduction togenetics; biochemistry and development; evolution and ecology. Laboratoryexercises will help students explore each topic using the scientific method.Hypothesis forming, data analysis and reporting will be essential componentsof the laboratory. An accompanying text will introduce students to Christianperspectives on current issues in molecular genetics and evolutionarytheory. (4 credits) Note: Does not count toward a biology major or minor.
