Updates about the latest accomplishments—including latest research, publications, and awards—by students, faculty, and staff
Dr. Villareal and colleagues published a study on Textbook Cost and Interactivity: Comparing Equity Outcomes and Student Perceptions in the Journal of Educational Research and Practice that investigated the impact of equitable access to course resources in the form of different e-textbooks in an introductory chemistry course. The purpose of the study was to determine if the use of a free textbook and/or the use of an interactive textbook enhances students’ academic performance, especially among students from marginalized backgrounds. Researchers analyzed equity data for 199 general chemistry students. Overall, the pattern of course equity gaps suggests there was a positive impact of implementing a free textbook on students’ grades, with the largest impact on racially minoritized students. However, there were no meaningful differences between interactive and noninteractive textbooks in grades. Further research is needed on equitable course resources and equity gaps in STEM.

He was advised by Kamila Larripa and supported by the National Science Foundation.
Dr. Shi Feng’s research explored the instructional strategies, key applications, and implementation challenges of teaching sustainability and resilience in engineering education. Using semi-structured interviews with engineering faculty, the study found that instructors commonly used strategies such as general discussions, project-based learning, and guest lectures.
Faculty identified practicality, the triple bottom line principle (people, planet, profit), and liability and environmental issues as the most important aspects of sustainability. For resilience, they emphasized resiliency itself and rapidity—the speed of recovery after a disruption—as the top priorities.
The most common challenge cited was time constraints. Despite this, students demonstrated improved knowledge and more positive attitudes toward sustainability and resilience after these approaches were implemented.
Dr. Shi Feng co-authored this study which investigated the intersection of these two phenomena: the role of mind wandering while listening to familiar/unfamiliar musical excerpts, and its effects on concurrent linguistic processing. Participants performed a lexical-semantic congruency task while listening to familiar or unfamiliar orchestral pieces, or a non-music sound clip. Mind wandering episodes were probed intermittently. We found that listening to familiar music, relative to unfamiliar music or environmental noise, was associated with faster lexical-semantic decisions and a lower incidence of mind wandering. We infer that familiar music increases task enjoyment, reduces mind wandering, and promotes more rapid lexical access during concurrent lexical processing.
Dr. Regina Jorgenson is helping lead an astronomical study investigating Fast Radio Bursts (FRBs)- powerful flashes of radio waves from deep space whose origins are of great interest to astronomers, yet not well understood. The project will support a post-baccalaureate fellow who will use some of the largest telescopes in the world to study the host galaxies of FRBs to better understand both the sources of these cosmic explosions, as well as the intergalactic matter through which the FRB signal travels – essentially giving us a new way to detect and measure previously unseen matter in the universe. Project funding comes from the National Science Foundation.

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.

For at least 25 years, students from the School of Engineering have successfully participated in the Consortium for Mathematics and Its Applications (COMAP) annual Mathematical Modeling Contest (MCM) and Interdisciplinary Contest in Modeling (ICM). The contest begins on a Thursday afternoon and ends on the following Monday evening. This year the competition started on January 23, 2025 and over 27,000 teams of up to three students from thousands of universities around the world produced a report summarizing their solution to one of six possible problems.
This year, two Environmental Resources Engineering (ERE) student teams of two students each from the Cal Poly Humboldt School of Engineering entered in the competition. Both teams selected an ICM problem focused on constructing a model to track habitat change from forest-to-farm over time as the ecosystem evolves along with accompanying agricultural choices. The analysis was required to include both natural processes as well as human decisions.
Competing against over 6,000 teams that selected this problem, the ERE team of Sayra Montesinos and Sean Ruzicka was awarded the score of Honorable Mention, with less than 10% of the 6,000 teams receiving a higher score. The ERE team of Roland Carter and Zander Leigh was awarded the score of Finalist, with less than 1% of the 6000 teams earning a higher score. Congratulations to Sayra, Sean, Roland and Zander for their achievement in this extremely competitive event. We appreciate your efforts which bring recognition to the School of Engineering at Cal Poly Humboldt!

Award Winner: Cheyenne Ty
Academics & Research: Outstanding Student of the Year
Cheyenne Ty was nominated by Sharon Tuttle and Kamila Larripa for the Outstanding Student of the Year award in the academics & research category.
Kami invited Cheyenne in Fall 2023 to join her National Science Foundation-funded project using mathematical models to investigate the impact of dysfunctional immune cells in the brain. A colleague gave her a very high recommendation after she took a mathematical proofs course with him.
Cheyenne has been the most outstanding undergraduate researcher I have worked with. She quickly came up to speed, devouring large volumes of peer-reviewed biological papers without a background in biology, learned a new coding language and became the expert coder in the group, and contributed a great deal to writing a manuscript, making figures, and overall project management in the first year together. She represented our group by presenting our project at the CSU Research Competition in April 2024. We published a paper from this work, and Cheyenne was with me every step of the way in terms of contributions, writing, revising and organizing supplemental material to be in line with best practices in reproducible research. She is the first author on this paper due to her excellent work.
We are in our second year together of the same project, and have welcomed three new students into the lab group. Cheyenne has stepped into a mentorship role, and continues to push the project ahead with her independence and self-motivation. She is able to explain the necessary biology to our new lab members as well as I can. We are now adding metabolic pathways to our model, and Cheyenne again is delving into the biology and translating mechanisms into code and running simulations. She is a wonderful role model for more junior lab members, and someone I can absolutely count on to contribute to the project with both her work ethic and scientific insights.
Cheyenne has two peer-reviewed publications (one as a first author) and has presented at multiple scientific conferences. This level of activity is quite extraordinary for an undergraduate student.
Her contribution to research projects in the areas of literature review, machine learning experiments, statistical and computational analysis, and programming has been exceptional. As a diligent student with a passion for both mathematics and computer science, her professionalism that surpasses her peers.
Congratulations Cheyenne!!
Dr. Barbara Clucas and graduate student Stephanie Stragier were awarded a grant from the Sequoia Park Zoo to support a study investigating habitat quality of the Western snowy plover, a threatened coastal bird species. In Humboldt County, some chicks are hatching at smaller body sizes, which may be linked to habitat degradation or climate change. This project will analyze chick measurements and habitat quality during the 2024–2025 breeding seasons to identify potential causes, ultimately aiming to inform conservation strategies for the species’ recovery and improve monitoring methods. This work will also provide research experience for Humboldt wildlife undergraduate students.
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.
Dr. Sean Craig received grant funding to hire undergraduate assistants in a study aimed at protecting and restoring kelp forests. Students will conduct fieldwork, including SCUBA diving in areas with dense sea urchin populations to assist with removal. Urchin overabundance can destroy kelp forests, creating “urchin barrens”- barren sea floors that are devoid of marine biodiversity and lacking in ecosystem health. The project will test different urchin removal frequencies and investigate environmental and ecological factors that support natural kelp recovery. Results will provide valuable insights to guide future kelp management and restoration.

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.
