Civil and Environmental Engineering Student Wins IDEA Grant for Groundbreaking Research
Cody O’Brien, a civil and environmental engineering student at Florida State University and the FAMU-FSU College of Engineering, is pioneering innovative research that transforms Florida’s invasive species problem into sustainable building solutions. His work explores how architectural materials can incorporate invasive species as additives, simultaneously strengthening construction materials and addressing environmental challenges.
As both a member of the Undergraduate Research Opportunity Program (UROP) and an IDEA Grant award winner, O’Brien has leveraged the college’s research infrastructure and partnerships to advance his groundbreaking studies. The FAMU-FSU College of Engineering’s strategic location at Innovation Park provides him access to world-class research facilities including the National High Magnetic Field Laboratory, the High-Performance Materials Institute, and the Resilient Infrastructure & Disaster Response Center.
Research Achievements and Academic Excellence
O’Brien’s most significant research breakthrough came through his IDEA Grant project, where he performed the first documented extraction of cellulose nanocrystals from the invasive algae species Sargassum muticum, commonly known as Japanese wireweed. Working with Associate Professor Qian Zhang in the joint college’s Department of Civil & Environmental Engineering during summer 2024, he examined these extracts using transmission electron microscopy and other advanced methods. His findings are summarized in an article pending submission to The Owl, FSU’s undergraduate research journal.
Through UROP, O’Brien collaborated with FAMU-FSU College of Engineering Professor Sungmoon Jung, a graduate student, and two undergraduates to design, create, and test clay bricks enhanced with small amounts of algae. The team documented improved strength in the enhanced materials and is working toward publication of their results.
“Florida State University provides so many opportunities for research to undergraduates through programs like UROP and the IDEA Grant,” O’Brien said.
Community Impact and Environmental Advocacy
Beyond the laboratory, O’Brien actively engages with the Tallahassee community through environmental advocacy and education. His work extends from the joint college campus to the Florida Capitol, where he advocates for environmental legislation through his involvement with the Surfrider Foundation.
In 2023, O’Brien participated in Coastal Recreation Hill Day, meeting with state lawmakers at the Florida Capitol to discuss key environmental and water-related legislation. The two bills he and fellow advocates supported passed later that year, resulting in improved environmental and water protections for Floridians.
Through FSU’s Environmental Service Program, O’Brien contributes to numerous environment-related community service projects throughout the Big Bend area. These initiatives include invasive species removal, native plant preservation, habitat restoration, beach and park cleanup and maintenance, water monitoring, and educational outreach.
One particularly impactful project involved creating a native species garden at a school in Wakulla County. “Projects like these will help ensure that conservation efforts are passed down through generations,” O’Brien explained.
Academic and Campus Engagement
O’Brien’s attraction to Florida State University stemmed from multiple factors that align perfectly with the FAMU-FSU College of Engineering’s mission. “Florida State University first drew me in with its vibrant campus and social life. Through its location at Innovation Park, the FAMU-FSU College of Engineering has close connections with research facilities like the National High Magnetic Field Laboratory, the High-Performance Materials Institute and the Resilient Infrastructure & Disaster Response Center, which gave me many opportunities to build my engineering and research career,” he said.
The university’s comprehensive approach to student development extends beyond research. O’Brien works as a tutor at the ACE Learning Studio and actively participates in the newly established Astronomy Club at FSU, where members coordinate dark-sky events during significant astronomical occurrences. He enjoys bringing his telescope and engaging in public outreach initiatives.
Future Impact and Research Continuation
O’Brien’s research discoveries are already inspiring the next generation of students. “I am optimistic that my discovery in nanocellulose extraction from Sargassum muticum could open the door to more research in finding sustainable uses of invasive plant species,” he said. As of this year, another FSU student has begun continuing research on nanocellulose extraction and testing.
