Species Richness and Composition of Raptors Between Urban and Rural Habitats
Presentation Year:2026
Kellan
Barney,
Undergraduate Student,
Wildlife
Urbanization has caused large areas of habitat to be completely transformed, forcing species to adapt or die. Raptors display a highly variable tolerance to urbanization from species to species, with some species excelling in urban environments and others failing. The aim of this study was to find the differences in species richness and composition of raptors between a rural and urban habitat. Species richness was higher in the rural habitat than in the urban one. There was also a difference in the community composition between the two habitats. Understanding how urbanization influences species richness and community composition is integral for future conservation efforts.
Species-specific Responses to Various Cat Food Bait
Presentation Year:2026
Kamiell
Wanner,
Undergraduate Student,
Wildlife
This research project investigates how different flavors of commercially available wet cat food utilized as bait influences wildlife visitation frequency and species diversity. 19 motion-activated trail cameras were deployed within a forested area in Humboldt County to compare wildlife responses. This study aims to assess species-specific attraction and deterrence effects of different bait flavors and test the hypothesis that certain bait flavors will significantly increase wildlife visitation frequency and diversity, while others will have neutral or deterrent effects on specific species. By examining how bait flavor influences visitation patterns, this research will provide insights to optimize bait selection for wildlife monitoring, inform wildlife management and conservation strategies, and contribute to methodological advancements in ecological field research.

Synthesis and Characterization of Gold Nanoparticles for Oncology Applications
Presentation Year:2026
Brodie
Lyons,
Undergraduate Student,
Chemistry
Gold nanoparticles (AuNPs) are used in experimental cancer treatments and developed in various shapes and sizes to optimize drug delivery, imaging, and photothermal therapy. In this study, small gold nanospheres (20-30 nm), large nanospheres (50-60 nm), nanorods, and nanostars were synthesized and analyzed. Dynamic light scattering, ultraviolet-visible spectroscopy, and transmission electron microscopy were techniques deployed to determine particle size, level of uniformity, particle absorption of light, and overall AuNP morphology. AuNPs shape and size changed which altered their interaction with light. Our results aid in informing AuNP design for future cancer treatments.
Synthetic EGF Receptor Drives Expansion of HPSC Derived Hepatocyte-Like Cells
Presentation Year:2026
Youyuan
Wang,
Graduate Student,
Biological Sciences
The liver can regenerate after injury. However, this unique capacity fails when disease or injury makes the organ hostile to transplanted cells. To address this challenge, we engineer hPSC-derived hepatocytes so they can better withstand this hostile environment and regenerate damaged tissue. We combine stem cell biology with synthetic receptor engineering to create hepatocytes with externally controllable proliferation. First, we tested that hPSCderived hepatocytes respond to epidermal growth factor (EGF). We then engineered an inducible EGF receptor (iEGFR) that activates hepatocyte proliferation in response to a dimerizing drug. This creates an "on/off" system, where proliferation is triggered by drug treatment and halted upon withdrawal. This work addresses a critical need: liver failure is a leading cause of death, and donor organ shortages leave many patients without treatment. Engineered hPSC-derived hepatocytes could provide a scalable regenerative therapy for these patients, bridging the gap of limited supply of donor organs.

As a College Corps Fellow, I served at the Boys and Girls Club of The Redwoods (BGCR) at Pacific Union Elementary School as a Youth Development Associate. Working with youth has developed my conflict resolution skills as well as communication skills in this field. I was grateful to be able to work with kids from TK-8th grade and act as a role model for them. BGCR operates an afterschool program on the campus of Pacific Union. The program facilitates care for members TK-8th grade and currently enrolls over half of the school population (approx. 296 members). With the sheer number of attendees on a daily basis, my position exists to fulfill staff/member ratios and provide an added element of safety for attendees.
The Effects of Restoration on Coastal Dune Arthropods
Presentation Year:2026
Markus
Orr,
Undergraduate Student,
Wildlife
Coastal dune ecosystems have been significantly altered through extensive vegetation removal and human development, and through the establishment of European beach grass. Arthropods play an important role in decomposition and nutrient cycling, and are highly sensitive to changes in vegetation structure. Thus, they are strong indicators of environmental changes and restoration success. This project aimed to evaluate the effects of dune restoration on arthropod abundance and species composition through comparison between restored and unrestored dune sites in the Humboldt County, California, which can then be used to evaluate the progress and success of restoration efforts.

The Influence of Dissenters and Social Control on Consensus and Entitativity
Presentation Year:2026
Hunter
Pons,
Graduate Student,
Psychology
This pilot study examines how dissent and social control influence perceptions of consensus and entitativity within groups. Drawing on social identity theory and subjective group dynamics, participants (N = 53) were exposed to varying levels of dissenters (1 vs. 10) and social control (present vs. absent). Results showed that consensus did not vary by condition but significantly predicted entitativity. Findings support the role of consensus in shaping group entitativity; a future study will test the relationship between consensus and group identification, mediated by entitativity and social identity uncertainty. Null effects suggest limitations in sample and contextual relevance.
The Mechanical-Human Mismatch: Fatigue and Injury Prevention In Motocross
Presentation Year:2026
Mark
Rivas,
Undergraduate Student,

A research project into the risks and causes of injury in the sport of motocross. The research is focused on how the athlete can be better prepared through sport specific training for better technique and other factors. The sport specific training can be developed through the perspective of a physical therapist to develop more durable athletes. With more research the perspective can be utilized in the set-up of the equipment on the motorcycle and the protective equipment riders use can be made safer. The practices and methods used by PT's could be very valuable to the growth of the sport by promoting safety and longevity for both competitive and recreational riders. A common saying in the sport is: "Its not if you're going to crash, its when" and with the impossibility of eliminating risk in a sport like motocross, a PT is in constant need by racers to get back to competition.
The Menstrual Cycle, Dual-Hormone Hypothesis, and Competition: Implications for Athletic Performance
Presentation Year:2026
Gaia
O'Neil,
Undergraduate Student,
Psychology
This study examines how testosterone and cortisol interact to influence competitive drive and athletic performance in female collegiate athletes. Guided by the dual-hormone hypothesis, researchers predicted that testosterone would enhance competitiveness when cortisol is low. Results showed a significant interaction predicting competitive drive, but no effect on sprint performance. Additionally, menstrual cycle phase did not significantly impact hormones, motivation, or performance, suggesting that hormonal fluctuations may shape psychological aspects of competition more than physical outcomes.
The Politicization of Performance: How Rome Turned Ancient Greek Ritualistic Entertainment Into Political Propaganda
Presentation Year:2026
Ava
Henderson,
Undergraduate Student,
Anthropology
In this poster the topic of how Ancient Greek ritualistic theater was changed to fit the bloody and politically inclined ideals of Ancient Rome was discussed. It explores different theoretical frameworks such as the Ritual Theory, the Spectacle and Power Theory, and the Performance Theory. It also uses many different methodologies including comparative archaeological analysis, textual analysis, and socio-political contextualization. Using these different methods the poster is able to explore how Rome used both their spectacles and their architecture to promote their idealization of war while Greece used their performances and architecture to honor their Gods, specifically Dionysus who was the God of theater. The poster specifically contrasts the changes in the architecture of theaters that reflect the changing ideals and the switch from comedic plays and tragedies that honor the Gods to violent games to promote the idea that being strong and winning is everything.

The Reproduction and Diet of the White Spotted Ratfish off Humboldt Bay
Presentation Year:2026
Sara
Johnson,
Undergraduate Student,
School of Engineering
Within the Class of Chondrichthyes or cartilaginous fishes is the poorly studied species of the white spotted ratfish, or Hydrolagus colliei. The objective of this project was to study this species’ diet and reproduction by analyzing stomach contents and gonads. We analyzed 8 males and 37 females. Fish were on average 52.48 cm in length with females being 10 cm longer than males. Fish fed on 4 prey groups, with benthic crustaceans being the most common, and females starting to reproduce at 53 cm length. Our data support previous studies suggesting that this species is a benthic feeder with sexual dimorphism, with females being larger than males and reproducing after they are 50 cm in length.

Toggles - The Social Media Co-op
Presentation Year:2026
Colin
Trevino-Odell,
Undergraduate Student,
Mathematics & Data Science
Social media is broken by design. Algorithms maximize engagement, not enjoyment. Anonymous accounts harass without consequence. Your data gets sold to advertisers. Creators get a fraction of the revenue their work generates. None of this is accidental. It's the business model. Toggles replaces it. Every member verifies with a real ID and stands behind their words. You control your feed by setting content categories to Off, On, or Max. Politics off, it's gone. Science on max, it's at the top. No ads, no investors, no data extraction. The platform is structured as a cooperative where revenue beyond operating costs goes back to creators and governance transitions to the community over time. I built toggles with claude code. It's live at toggles.cc
