Dr. Sara Sybesma Tolsma ’84 Professor of Biology
Ph.D., Northwestern University
B.A., Northwestern College (Iowa)
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. She has three ongoing research projects. In collaboration with Dr. Laura Furlong, she is studying mayfly genetic variation in Northwest Iowa watersheds and in streams on Santa Cruz Island. With her Cell Biology students, she is measuring the anti-proliferative effects of plant extracts and chemicals in those extracts on human tumor cells in vitro. Finally, as a member of the HHMI-sponsored SEA-PHAGES group, she is working on annotating mycobacteriophage genomes with students in her genetics and genomics class. She is expanding her phage research by raising antibodies to phage capsid proteins with her immunology students. She is also passionate about integrating science and Christian faith. She is an American Scientific Affiliation Fellow and serves as a subject book review editor for their journal, PSCF. She has published a number of essays in Perspectives: A Journal of Reformed Thought, which she co-edits, and she wrote a book with Dr. Jason Lief about the importance of engaging young people in conversations about science and faith. 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
A fee is associated with this course (http://www.nwciowa.edu/tuition/fees).
- Honors First-Year Seminar: Speaking and Writing in Community
(4 credits) NWC105 is an Honors section of the First-Year Seminar, utilizing the samesyllabus, texts, and course objectives as NWC101. In addition, the HonorsFirst-Year Seminar aims: 1) to promote community among first-year studentsof demonstrated academic ability; 2) to create an environment in which thesestudents can excel academically and nurture their innate intellectualcuriosity; and 3) to provide students with an opportunity to learn from NWCfaculty who have been recognized for their teaching excellence in theclassroom. Completion of the Honors First-Year Seminar does not guaranteeadmission into the Honors Program. Students will have the opportunity toapply to the Honors Program at the end of their Freshman year. Foradditional course information, see the course description under "First-YearSeminar".
