College of Natural Resources & Sciences
Get Your Hands Dirty Studying Science on California’s North Coast
There’s no better place to study science than at Cal Poly Humboldt. Our community is a living laboratory with the Pacific Ocean, ancient redwoods, and other diverse ecosystems for you to explore.
The College of Natural Resources & Sciences boasts a wide variety of science-focused areas of study, from biochemistry to zoology. Our multiple fieldwork opportunities, Place-Based Learning Communities, and extensive research faculties paired with our stellar faculty and staff create an environment for you to feel inspired, challenged, and engaged with the science all around you.
Undergraduate Research
Many universities reserve research experience for graduate students. At Cal Poly Humboldt, you may conduct your own research or assist professors with their projects as early as your freshman year. Either way, you’ll put theory into practice, building a fundamental understanding of concepts and methodologies. With opportunities to present at local and national conferences, you’ll learn how to explain your findings, too. Experiences like these offer a glimpse of what it’s like to be a professional scientist and will help you discover your passion.
Fieldwork
Located on the North Coast of California, Humboldt is surrounded by ancient redwoods and close to the Pacific Ocean, mountains, and rivers. You’ll find the region’s natural environment is the perfect outdoor classroom where learning happens through real-world experience. Track elk, hike through forests to measure redwoods, or take water samples from California’s second largest river—Humboldt provides a wide range of opportunities for fieldwork, which helps develop critical thinking and collaboration skills, and a passion for learning that will take you far in life.
Personal Attention
College is a time to expand your horizons and find out who you really are, and our attentive faculty are here to support you every step of the way. From the moment you begin your program, you won’t be just another face in the crowd. You’ll be part of a community as you get to know your professors. They’ll challenge you, but they’re accessible, too. Whether through mentoring or one-on-one feedback, they’ll help you build the knowledge and skills to be successful at Cal Poly Humboldt.
Undergraduate Programs
Cal Poly Humboldt offers a wide array of science majors and programs, led by highly skilled faculty who foster a supportive environment. You will develop the critical thinking skills needed to solve complex problems in science, engineering, and natural resources, leaving you well-prepared for professional careers and higher levels of study.
Graduate Programs
Cal Poly Humboldt has an established reputation for its graduate programs in the biological, environmental, engineering, and natural resources sciences, which provide the knowledge and experience necessary to address today’s scientific problems.
Equipped for Excellence
Cal Poly Humboldt has a diverse range of research facilities, labs, and special collections as essential tools for conducting research and gaining real-world experience. Utilizing a renewable energy technology research center, a marine laboratory, and the largest botanical collection in the CSU system, you will actively engage with research during your undergraduate years.
Place-Based Learning Communities
Learning goes beyond the classroom at Humboldt—we learn from the environment we are in. Our Place-Based Learning Communities provide you with a tight-knit community of like minded peers before classes even start.
We start right away—you’ll be immersed in major-related fieldwork, seminars, and classes with students like you before the semester even begins. These connections will help you navigate college life, gain confidence, succeed academically, and gain a sense of belonging within the Humboldt community.
Alumni Updates
Danial Nayeri
Wildlife, 2023
After earning his master’s degree in Wildlife from Cal Poly Humboldt, Danial moved to College Station, Texas, to begin a new journey as a Ph.D. student. Danial is currently a research graduate assistant at Texas A&M University, working in the Human Dimensions of Natural Resources Lab under the supervision of Dr. Gerard Kyle. Danial's research focuses on human-wildlife conflict mitigation through the lens of social psychology. His experience at Humboldt helped shape him into a more competent and prepared graduate student.
Warren Marchioni
Biological Sciences, 1965
Warren's Master's Degree helped him get employed as a fishery biologist for the U.S. Bureau of Fish and Game at Sandy Hook Marine Laboratory in New Jersey where he researched the behavior of striped bass. He later transitioned to becoming a science educator at the secondary and university level. After his retirement, he continued to work part-time at Liberty Science Center. At the age of 80, he thought it was time for a complete retirement. His wife Ann was also an educator. They currently are involved in establishing pollinator gardens in our community, enjoy biking, and recently celebrated their 50th anniversary. Warren's interest in photography comes in handy when they visit their daughter who is an instructor in Alaska.
Captain Paul C. Golden, U.S. Coast Guard Ret.
Fisheries Biology, 1970
Paul joined the Coast Guard, with his marine environmental background was assigned to the White House to draft the first Federal Environmental Impact Statement, for the TransAlaskan Pipeline. He spent two years patrolling the Bering Sea protecting the “Deadliest Catch” fishing fleets. A second White House tour coordinated Pacific Basin interagency drug interdiction operations. Two years in the Persian Gulf/Africa dealing with Pirates, Smugglers & Terrorists. Retired from the Coast Guard, the next 14 years were with the Intelligence Community. Four Masters: Univ. Michigan-Environmental Management, Naval War College-National Security Planning & Risk Management, Salve Regina-International Affairs, CalState Hayward-Government Pandemic Management.

Sean Stewart, Kerry Byrne
Environmental Science & Management
Sean Stewart has published the first chapter of his thesis in the journal Restoration Ecology. For this research, Stewart and his M.S. advisor, Dr. Kerry Byrne, compared long-term demographic data and survival of transplanted (9 year) and extant (7 years) individuals of Applegate's milkvetch within the same population. Applegate's milkvetch is a Federally Endangered plant species found only near or within the city limits of Klamath Falls, Oregon. The results of this study suggest that population reinforcement can be a successful conservation tool for Applegate's milkvetch under the right conditions and the study may be used as a tool to inform conservation strategies for other imperiled herbaceous perennial plant species.

Sean returned to Humboldt State as a non-traditional student and earned his B.S. and M.S. in the ESM Department. He was the 2021 recipient of the McCrone graduate student fellowship award.
Kerry Byrne (ESM), Justin Luong (FFRM)
Environmental Science & Management
Drs. Kerry Byrne (ESM) and Justin Luong co-led a manuscript published in the journal Ecosphere. The study describes the results of a 4-year drought experiment in southern Oregon on two understudied sagebrush species. They found that severe drought had divergent effects on two adjacent plant communities with differing dominant sagebrush species (low sagebrush and silver sagebrush).

Pedro Peloso
Biological Sciences
Dr. Pedro Peloso co-authored a publication with colleagues from multiple institutions focused on the evolutionary history and biogeography of the largest genus of Treefrogs in the Americas (Dendropsophus). They also assessed the evolution of egg deposition mode (aquatic vs. terrestrial). The paper was published in the journal Molecular Phylogenetics and Evolution.
