Achievements

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.

Joshua Smith

Chemistry

Chemistry & Biochemistry faculty Joshua Smith is a co-author on a paper with an international team working on using triplet state Baird-aromaticity in photosensitive processes. In this study triplet state Baird-aromaticity is used to stabilize the quencher molecules used in fluorescence imaging. The paper was published in the Royal Chemical Society's open access journal, Chemical Science.

Justin Luong

Forestry, Fire & Rangeland Management

Dr. Justin Luong received CSU Agricultural Research Institute funding to assess how solar micro grids affect coastal prairie plant communities and soil properties. The study aims to determine land use strategies that maximize ecosystem services for native plant biodiversity, sheep forage, and solar energy. The project involves mentorship and training for undergraduate (Gabriel Abundis, Claudia Alfaro-Hernandez, Logan Holey) students and a graduate student (Angelina Garcia) to improve retention of diverse natural resource managers and scientists in rangeland sciences. Results of this study will inform California policy related to rangeland management and solar energy, as well as natural resource management. 

Cynthia Le Doux-Bloom

Fisheries Biology

Dr. Cynthia LeDoux-Bloom received a $145,000 grant from the North Coast Regional Water Quality Control Board to develop a monitoring strategy for improving the effectiveness of water quality, sediment, and flow monitoring efforts throughout the Elk River (Humboldt Co.) watershed. The monitoring strategy will be developed in conjunction with the Science and Coordinated Monitoring Workgroup composed of government agencies, non-profit agencies, and landowners. Findings shall serve as the basis for a monitoring plan.

Logan Holey, Angelina Garcia

Forestry, Fire & Rangeland Management

Angelina Garcia and Logan Holey received competitive research grants from the California Native Grassland Association (CNGA) to conduct research with Dr. Justin Luong. Logan will examine how local solar microgrid energy developments influence physical rangeland characteristics that result in microhabitats for plant communities, and Angelina will explore how targeted invasive species removal on affects rangeland soil health.

Sarah Jaquette Ray

Environmental Studies

Environmental Studies Chair Dr. Sarah Jaquette Ray will moderate a discussion with Joe Hendersen, Nikki Hoskins, Jade Sasser, Rebecca Weston, and Finn Does on how the climate crisis has been mobilized in service of authoritarian nationalism, anti-immigrant xenophobia and misogyny.  Learn more and register here: https://www.climatepsychology.us/cpa-workshops-and-talks-aNVzu/unnaming…

Claire Till, Matthew Hurst, Ben Freiberger

Chemistry

Chemistry faculty Claire Till and Matt Hurst, along with alumni Ben Freiberger, led a paper just published in the Journal of Geophysical Research: Oceans. This paper came from their fieldwork at sea off the coast of California and Oregon, and is compares the chemical reactivity and distribution of the essential nutrient iron with a potential tool to study it: scandium

Justin Luong

Forestry, Fire & Rangeland Management

Led by a previous undergraduate student mentee, Dr. Justin Luong co-published a paper in American Journal of Botany. The paper uses eDNA to explore microbial communities in the rhizosphere of an endangered species, Lupinus nipomensis, and characterizes differences in different field microhabitats. The study also looks at how microbial communities differ in field and greenhouse conditions.

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.
