Department of Biological Sciences
Ignite your passion for biology at Cal Poly Humboldt.
With our ecologically diverse landscape, state-of-the-art research facilities and faculty dedicated to hands-on learning, Humboldt is the perfect place to jumpstart your scientific future.
Bachelor's Degree Programs
The Department of Biological Sciences offers four major disciplines that explore the intricacies of living organisms from the microscopic to the magnificent. You have the opportunity to double-major using combinations of Biology, Botany, Marine Biology and Zoology degrees. In this case, you must take at least three courses that are unique to the second major and total at least 10 units. The courses must be selected with the student's advisor and approved by the Department Chair.
Biology, B.S.
Learn about organisms and how they function in the natural world. Study general biology, or focus your studies by choosing a concentration in one of five specialty areas: General Biology, Cellular and Molecular Biology, Ecology, Microbiology, or Science Education.
Botany, B.S.
As a botany major, you’ll flourish while studying the biological processes unique to plant life. Students in the botany program are part of a dedicated learning community and have access to the best botanical collections in the CSU system.
Marine Biology, B.S.
Using the nearby Pacific Ocean and North Coast as a living lab, marine biology students gain real-world experience on and in the ocean, beaches, and other local marine habitats studying organisms and ecosystems.
Zoology, B.S.
Study physiology, ecology, anatomy, and classification of animal groups—with opportunities for field research in our diverse local habitats, as well as laboratory experience.
Master's Degree & Pre-Professional Programs
In the Biological Sciences department, you can get a masters in Biology or enter our Pre-Professional programs.
Biology, M.S.
As a Master of Science student in Biological Sciences, you will pursue investigations with an emphasis in the laboratory, forests, marine habitats, or a variety of other settings.
Pre-Professional
If you choose one of our pre-professional health programs—which include pre-medical, pre-dental, and pre-veterinary—you will receive a core education based in biology, chemistry, physics, zoology, and mathematics.
Research Facilities and Collections
At Cal Poly Humboldt, our extensive research facilities and collections set students up for excellence in the biological sciences. Utilizing our ocean-going research vessel, greenhouse, electron microscopes, Vertebrate Museum, and more, you’ll work side by side with other students and faculty to research what you talk about in the classroom, providing real-world, hands-on experience even as an undergraduate student.

Mihai Tomescu
Biological Sciences
Botany Professor Mihai Tomescu gave an invited lecture titled,What can we learn from 400-million-years old fossils about plant evolution?, at the 90th meeting of the Botanical Society of Japan in Noda, Japan, September 4, 2026.
Monica Sheffer & Benjamin Hanlin
Biological Sciences
Dr. Monica Sheffer and master’s student Benjamin Hanlin received funding to investigate how spider communities reflect the health of California's redwood forests. The project will compare spider diversity in old-growth, unthinned second-growth, and restoration-thinned forests in Redwood National and State Parks. Because spiders play important roles as predators and prey, changes in their communities could provide valuable clues about how redwood forests recover after restoration. Led by Hanlin with Sheffer serving as faculty mentor, the research will establish baseline biodiversity data to help evaluate restoration efforts and support monitoring of redwood forest ecosystems.
Funding comes from Save the Redwoods League.
Dr. Oscar M. Vargas, Eli Allen
Biological Sciences
Oscar Vargas, Associate Professor of Botany in the Biological Sciences Department, along with M.Sc. graduate Eli Allen (currently a PhD student at UC-Santa Cruz), published an article documenting a case of budding speciation in the California Floristic Province. This mode of speciation, thought to be rare in nature, is being found in plants, especially regions with high biodiversity. The article "A case of budding speciation in the California Floristic Province and infraspecific divergence in Abronia villosa" is available at the following link https://doi.org/10.1002/ajb2.70234
