CSCI Highlights
Dr. Oikawa & Students Present Regenerative Ag Climate Solutions at AGU
Our Earth and Environmental Sciences department sent a contingent of researchers to the American Geophysical Union meeting in December in Washington DC, including professors Patty Oikawa and Emilio Grande and students Inbar Amitay, Monica Esqueda, Loren Tolley-Man, Eduardo Gamez, Jr., Mirana Ridout, and Ashley Walsh. A promotional video featuring the work of Dr. Oikawa’s research lab and collaborators at Chico State investigating the climate mitigation impacts of regenerative agriculture was aired on monitors throughout the weeklong conference.
Professor Livaudais & Public Health Students Present Body Positivity Research at PRISM
Students Kianna Cortez-Garcia and Angie Arroyo and Assistant Professor, Mia Livaudais, Public Health presented at PRISM, a health symposium on social media and health. This abstract summarizes their research. Body positivity and body neutrality have become prominent movements on social media platforms, particularly TikTok, where diverse voices engage with these concepts in unique ways. While body positivity celebrates all body types and aims to challenge societal beauty standards, body neutrality focuses on detaching self-worth from physical appearance. This study aims to perform a content and sentiment analysis of TikTok videos to examine the portrayal of body positivity and neutrality, with a focus on understanding how BIPOC influencers shape these narratives in comparison to non-BIPOC creators.
Ceremonial Burn at Concord Center Provides Opportunities for Education, Community Building and Environmental Research
A ceremonial burn occurred October 26th at the Concord Center as part of an EPA-funded collaborative project with Kate Shade and Canyon Steinzig, Nursing, Kathy Cutting, Concord Center and Galindo Creek Field Station Coordinator, Tony Marks-Block, Anthropology, Geology, and Environmental Studies, Ohlone tribal members, and the Contra Costa Resource Conservation District. This burn is a cultural ceremony and a means of sharing traditional ecological knowledge and Indigenous land stewardship practices. It is the first time the Ohlone community of midlife, youth, and children have been able to conduct a ceremonial burn for their generation. The burn not only serves as an educational and community-building activity, but will also provide an opportunity for environmental research.
Ruth Tinnacher, Chemistry & Biochemistry, plans to evaluate the effects of wildfire ash, on plant growth and development, after its deposition on plant leaves and top soils. Wildfire ash is a complex chemical mixture potentially containing micro- and macronutrients, as well as toxins. In this collaborative study, CSUEB students will characterize ash samples from this ceremonial burn and the McKinney wildfire, collected by our USGS collaborators (Andrea Foster and Courtney Creamer). Under the guidance of Claudia Uhde-Stone (Biological Sciences) and Ruth Tinnacher (Chemistry & Biochemistry), students will apply ash extracts to plant leaves, and evaluate any potential changes in plant weights in a controlled, lab-scale growth experiment with a model plant (Arabidopsis thaliana). Additionally, plant health and plant stress responses will be characterized based on biochemical assays under the mentoring of Monika Sommerhalter (Chemistry & Biochemistry). Finally, the imaging and spectroscopic analyses of ash and leaf samples with a recently-acquired SEM-EDS at CSUEB and the synchrotron facilities at the Stanford Radiation Light Source (SSRL) will allow the researchers to characterize potential uptake mechanisms of ash components by plant leaves, under the guidance of Stephanie Zaleski (Chemistry & Biochemistry), Amrita Bhattacharyya (University of San Francisco), and Sam Webb (SSRL).
The long-term goal of this project is to predict the impacts of wildfire ash deposition on plants, contribute to the development of any necessary mitigation steps, and protect natural resources, while learning from the long-standing land management traditions of the Ohlone people.
CSUEB Students Make Their Mark SACNAS Conference
CSUEB students presented posters at the SACNAS (Society for the Advancement of Chicanos/Hispanics and Native Americans in Science) in October 2024. Shown here are Gabriel Lee, undergraduate, Sagar Shah, graduate student, and Allie Hurley, CSUEB alum and current single subject math credential student. Gabe’s poster presents an overview of the guided self-placement program as part of the ACT UP grant, awarded to MATH professor, Simone Sisneros-Thiry, in which first-time freshmen were given more agency to choose their initial MATH course at East Bay. The students gained a great deal from their attendance. Sagar notes "Being able to attend panels and get questions answered was invaluable."
Beyond the Classroom:
CS Students Connect with Tech Leaders
Computer Science students in Ahmed Banafa’s classes enjoyed presentations with guest lecturers working professionally. Students in Operating Systems, CS421, were visited by Abood Quraini from NVIDIA. His insightful presentation covered various aspects of AI as well as job opportunities, challenges facing graduates, and tips on interview preparation. Khalil Estell from Google helped develop the operating system used in Pixel devices. He shared practical knowledge about operating systems, their applications, and finding job opportunities.
In CS441, Computer Networking, students were visited by Jonathan Kaldani of NASA Ames Research Center. He delved into the future of NASA, cybersecurity initiatives at NASA, and valuable career insights including information about jobs and internships.
Earth and Environmental Sciences Dept. Sheds Light on Storm Origins
In the Spring of 2023, Earth and Environmental Sciences Assistant Professor Emilio Grande and Professor Jean Moran requested help from CSUEB Students, Faculty, and Staff to collect rain samples from their homes during two storm events. They used the samples to study the stable water isotopes of the two storms. These storms were special because they originated in different parts of the Pacific Ocean. Winter Storm Olive, coming from the North Pacific, hit the Bay Area at the end of February 2023. A few days later, in early March 2023, an Atmospheric River hit the Bay Area, coming from the Equatorial Pacific. As the researchers expected, these two storms had very different isotopic signatures. Professors Grande and Moran, with the help of Alumna Brenda Karina Delgadillo Moreno, used the data to show the applicability of studying these types of storm events to track water through watersheds and different landscapes. They hope the techniques used can be further applied to water resources management. The research was published in the journal Hydrological Sciences and can be accessed through
“Fun” at the Fungarium!
Did you know that ÂãÁÄÖ±²¥ has a fungarium or even what that is? The fungarium currently includes over 6000 fungal specimens, with several thousand additional specimens expected to be added to the collection in 2024-2025. The collection consists primarily of specimens from California, Hawai'i and Vanuatu, including vouchers resulting from the research projects of Dr. Brian Perry and students, as well as the ongoing California Fungal Diversity Survey project. Thanks to a generous grant from the California Institute for Biodiversity, the fungarium recently added twelve new specimen storage cabinets, tripling the capacity of the space. Here we see Biology undergraduates, Sannah Alimi and Warren Cardimnona, working on the collection!
Neurophysiology and Behavior Lab Shines at Society for Neuroscience conference
Members of the Neurophysiology and Behavior Lab, led by Dr. Divya Sitaraman (Associate Professor of Psychology), presented three research posters at the Society for Neuroscience conference, October 4-9, 2024, in Chicago, IL. Graduate students Namrata Dhungana and Yi Shen Lee showcased their research on the neural mechanisms underlying egg-laying decision-making, while research technician Preeti Sundaramurthi presented her work on sleep circuits. Dr. Sitaraman presented on new educational curricular modules for mapping neural circuits using fly and mouse connectome data. Research and travel were generously supported by the College of Science, NIH 2R15GM125073-03, and NSF CAREER 2042873 grants awarded to Dr. Sitaraman. Additional travel and research support came from the Faculty for Undergraduate Neuroscience award to Yi Shen Lee, the Society for Neuroscience travel award to Namrata Dhungana, and Association for Women in Science to Preeti Sundaramurthi.
CSUEB CONNECTS WITH HIGH SCHOOL STUDENTS IN SUMMER BRIDGE PROGRAM
This summer, CSUEB students and faculty supported science discovery during a summer bridge program for high school students held at the College of Alameda. The program was funded by the National Science Foundation, HSI Pilot Project: MESA Connect. Led by Professor Monika Sommerhalter, Department of Chemistry and Biochemistry, CSUEB students Christian Farinas, Rafael Cazares, Boquan Huang, and Vi Truong helped design and run engaging science activities for the high school students. In the “Biotechnology” lab, students determined if they had zero, one, or two alleles of a particular insertion (a “jumping gene”). Since different populations have different insertion frequencies, this experiment invited the students to discuss their families’ genetic origins. CSUEB Alumna, Emily Quach, was the instructor of the program. In the “Air Monitoring” lab, the CSUEB students helped Dr. Alex Madonik to engage high school students in collecting and analyzing data on carbon dioxide and particulate levels in their neighborhoods. Co-Interim Dean Julie Glass visited the program and ran an activity for students to explore the different degree programs and career opportunities offered by the College of Science.
HOW DO WILDFIRES AFFECT CA’S NATIVE INSECTS?
As the climate warms, wildfires are increasing in frequency and intensity in California. While fire is a natural part of the landscape, global warming, drought, a long history of fire suppression, and invasive species that can kill trees are creating extreme fire conditions. It is important to understand how these changing conditions can impact already endangered California native species. This summer, CSUEB undergraduate students, Diana Montes and Paulina Lara, from Dr. Hazlehurst's Ecology lab worked with the US Forest Service to document the insect pollinators of several endangered plants in the El Dorado National Forest in the Sierra Nevada mountains. Students spent several days hiking and camping in the forest while collecting specimens in areas that burned in the Caldor and Mosquito fires. The results of the surveys will inform critical ecosystem conservation efforts to shield vulnerable species from the effects of anthropogenic climate change.
