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.

Pedro Peloso
Biological Sciences
Biological Sciences faculty Dr. Pedro Peloso was a senior author on a new paper addressing long-standing confusion in the naming of a group of South American tree frogs (genus Boana, family Hylidae). The study was led by Gisele Cassundé, one of Peloso’s former students from Brazil. Using a combination of genetic and anatomical data, along with an extensive review of literature spanning two centuries, the authors resolved a complex taxonomic puzzle—clarifying species identities and providing a foundation for the description of several new species. The paper was published in the journal Zootaxa.

Alyssa Semerdjian
Biological Sciences
Alyssa Semerdjian received a Ranges Imaging Mini-Award for a project that will use 3D models generated from MicroCT scans to study nasal turbinates - tiny bones inside the noses of mammals that help them maintain body temperatures and conserve water. The study will focus on rodents from the family Heteromyidae. Members of this family can be found across North and Central American from extremely dry deserts to wet tropical forests. This work will provide new insights into the adaptive significance of nasal turbinates, and how morphology and physiology can vary in closely related small mammal species that occupy different habitats.
Jordyn Neal, Sam Rodrigues, Allison Bronson
Biological Sciences
Undergraduate alumna Jordyn Neal (now an M.S. candidate at CSU Fullerton) & Assistant Professor Allison Bronson had their recent publication in the Anatomical Record featured as the journal's "Editor's Choice" article for May 2025. The publication described inner ear shape in four species of sharks, part of a team effort including undergraduate alumna Samantha Rodrigues and data scientist John Denton. The Editor's Choice interview with Neal & Bronson is available through the American Association for Anatomy website.
