turtle grazing on algae
Native honu are acting as reef defenders by grazing on invasive algae that threaten Papahānaumokuākea coral.

An invasive algae already well-established in the Northwestern Hawaiian Islands is raising concern among researchers as it threatens to spread into the main Hawaiian Islands. Scientists from the University of Âé¶¹´«Ã½ at Mānoa and the U.S. Fish and Wildlife Service (USFWS) have identified a potential ally in slowing its advance: sea turtles.

UH Mānoa researchers captured the first footage of green sea turtles helping control aggressive invasive algae.

Hawaiian green sea turtles (honu) have been documented for the first time actively grazing on Chondria tumulosa, an aggressive invasive red alga that has spread rapidly across reefs among three of the northernmost atolls in Papahānaumokuākea Marine National Monument (PMNM).

The findings, recently published in the journal by researchers, suggest that honu may play a meaningful role in controlling this ecologically damaging species—while also potentially spreading it.

“After these exciting finds, our multi-partner effort to prevent this seaweed from taking hold in the Main Hawaiian Islands must include a plan to increase numbers of threatened, native green sea turtles, as well as ramping up efforts to identify all routes that could allow Chondria to spread to Oʻahu,” said Celia Smith, UH Mānoa‘s professor and senior author of the study.

Dangers of C. tumulosa

closeup of invasive algae
The invasive red alga Chondria tumulosa forms thick, suffocating mats that smother native coral and threaten Âé¶¹´«Ã½â€™s reef ecosystems.

First detected at Manawai (Pearl and Hermes Atoll) in 2016, C. tumulosa has since expanded to more than 101 square kilometers of reef habitat (nearly the size of Kahoʻolawe), including Kuaihelani (Midway Atoll) in 2021 and Hōlanikū (Kure Atoll) in 2022. The alga forms dense mats more than 6 centimeters thick that can smother live coral and displace native reef species, making it one of the most pressing threats to the monument’s reef ecosystems.

Turtles take a bite

Using a stationary GoPro camera deployed on a reef at Midway Atoll in June and July 2025, the research team captured approximately 50 minutes of footage showing three honu grazing on C. tumulosa mats. One female took up to 18 bites in a 95-second burst, leaving disruptions 5–15 cm in diameter across the algal canopy—substantially larger than what urchins or fish could achieve. A complementary necropsy of a stranded adult female confirmed C. tumulosa fragments throughout her digestive tract, accounting for roughly 25% of the material in her esophagus and crop.

“These turtles are consuming a meaningful amount of this alga in a single foraging session,” said Tammy Summers, USFWS staff biologist and co-author of the study. “It’s exciting because it points to honu as a native megaherbivore with the potential to suppress C. tumulosa biomass—but it also raises important questions about whether fragments excreted during their migrations between atolls could accelerate the alga’s spread.”

The findings carry immediate management implications. Because 96% of Hawaiian green sea turtles nesting occurs at Lalo (French Frigate Shoals) before individuals disperse to foraging grounds across the archipelago, the authors recommend eDNA monitoring at Lalo to track potential spread of C. tumulosa beyond its known range.

The study was a collaboration between UH Mānoa‘s School of Life Sciences and USFWS Midway Atoll National Wildlife Refuge, and was funded by USFWS Invasive Species Strike Team funds through a cooperative agreement with UH Mānoa. Smith leads the Limu Lab at UH Mānoa, where research on C. tumulosa physiology, distribution and ecology has been ongoing for several years. Other authors on the paper are Caroline Pott from USFWS and Angela Richards Donà from the School of Life Sciences.

This work was accomplished under permit numbers PMNM-2025-001, USFWS 274 Recovery Permit TE72088A-3, Recovery Sub-permit TE163899-2, NOAA Permit 21260, and 275 State of Âé¶¹´«Ã½, Department of Land and Natural Resources Special Activity Permit 2026-01.

Malik Younsi

A University of Âé¶¹´«Ã½ at Mānoa faculty member has earned international recognition for research that advances understanding in a key area of modern mathematics.

graphic of circles

Department Chair and Associate Professor Malik Younsi received the 2026 Frontiers of Science Award from the International Congress of Basic Science (ICBS). The honor recognizes major breakthroughs in mathematics, physics and engineering.

Younsi was recognized for a research paper co-authored with Dimitrios Ntalampekos on conformal maps, a topic in complex analysis that studies how shapes in the plane can be transformed while preserving angles. In simple terms, it looks at how you can stretch or reshape something—such as a map or a piece of rubber—without changing the way angles and corners fit together, similar to how digital maps adjust views while keeping locations accurate.

“Mathematics is often about finding hidden structure in things that seem complicated at first,” Younsi said. “This recognition highlights the value of staying curious and patient, and I hope it encourages students to see that even abstract ideas can lead to meaningful discoveries.”

The 55-page paper, published in Inventiones Mathematicae, looks at when flat shapes can be transformed into ones bounded by circles and points, building on a long-standing question called the Koebe uniformization conjecture. The research helps describe when there is essentially just one possible way to do transformation, giving a clearer understanding of how these shapes work.

The Frontiers of Science Award, launched in 2023, recognizes recent papers with lasting impact after a competitive global review process. Younsi’s work was selected by an international panel of experts for its contribution to complex analysis. He will be honored at the 2026 ICBS meeting in Beijing on August 9, where leading scientists from around the world will gather to present and discuss new discoveries.

Bartz’s research leverages cutting-edge environmental DNA (eDNA) technologies combined with local ecological knowledge shared by the community to monitor marine biodiversity and assess critical habitats. She developed a novel, low-cost eDNA water filtration system, which has the potential to revolutionize marine biodiversity monitoring by making it more accessible and cost-effective, particularly in resource-limited settings. This project was supported by the Patents2Products Fellowship through the UH Office of Innovation and Commercialization.

“It’s an honor to be part of a global group of women working to advance STEM, and I am very thankful for the opportunities I’ve found through the Zonta Club,” Bartz said. “I’ve connected with this phenomenal network of women supporting women. My goal is to make marine research more accessible while working alongside local communities to protect culturally and ecologically important species.”

Bartz’s dissertation examines the disappearance of a culturally and ecologically significant shark species in Âé¶¹´«Ã½. Her research, which confirmed a shark nursery habitat in Hilo Bay, contributed to the area’s first formal recognition as a vital shark habitat by the International Union for Conservation of Nature.

The Zonta Women in STEM Award uplifts innovation and celebrates the remarkable accomplishments of women between 18-35 years of age in STEM fields and acknowledges their groundbreaking research, pioneering discoveries, and/or exemplary contributions to advancing knowledge and innovation in a STEM field.

Competing against 37 colleges, UH Mānoa once again took first place for “highest point average,” as well as a close second place for the overall team championship, asserting its place among the nation’s top ballroom dance college teams. Winning top honors in the highest point average requires most team members to perform exceptionally well in all events.

The dancers of the Ballroom Dance Club @UHM—a registered independent organization at UH Mānoa—are trained and coached by Ravi Narayan and Synthia Sumukti. Narayan and Sumukti also represented Âé¶¹´«Ã½ in the senior age division placing 1st in several events.

“We are no longer the underdogs, so all the other colleges are looking at us as the team to beat,” said Narayan, who is also an adjunct faculty member in the UH Mānoa . “The bar is getting raised higher and higher each year, but we prevailed once again. We are incredibly proud of the dedication of our dancers who put in many hours to prepare for this competition. We are grateful for the incredible support we have received from the entire ballroom community in the state of Âé¶¹´«Ã½.”

The Ballroom Dance Club @UHM was formed in September 2022, and the team took first place for “highest team average” in 2024 and 2025.

“Nationals was an amazing and eye-opening experience for me,” said Caleb Zerbe, who competed in the nationals for the first time. “Getting to see so many people dance and enjoy themselves on the floor made me realize how fun dancing can be, even at the highest stages. It was a moment that helped me build a lot of confidence, and one that I will never forget.”

Christopher Ramirez, who competed on all three victorious UH Mānoa teams, added, “Given the opportunity to compete at my third nationals, there is always something new to learn. Winning for the third year in a row has reminded me just how incredible it is to be a part of this team.”

Tough competition

NCDC is a grueling competition with events starting at 7 a.m. every morning. It consisted of multiple events based on proficiency (bronze, silver, gold, etc.). Each student danced in up to 32 different events at the bronze and silver skill levels. They competed in all four styles of ballroom dance including International Standard (waltz, tango, viennese waltz, foxtrot and quickstep), American Smooth (waltz, tango, foxtrot and viennese waltz), American Rhythm (chacha, rumba, swing, bolero and mambo) and International Latin (samba, chacha, rumba, paso doble and jive).

Team ʻĀina deploys its on-the-ground robot to inspect pineapple fields. Google is supporting UH research to advance robotic perception, including AI, 3D vision and touch sensing for agriculture, health-related human-robot interaction and real-world environments.

The University of Âé¶¹´«Ã½ at Mānoa has received a $50,000 research gift from Google to support artificial intelligence and robotics work led by Assistant Professor .

The gift will fund Chen’s research in robotic perception, a field focused on helping machines better understand and interact with the physical world. The research includes applications in health-related human-robot interaction, tactile sensing and agriculture.

“This support allows us to explore bold ideas at the intersection of perception and real-world environments, while creating hands-on opportunities for students to work on technologies that could shape the future of robotics,” Chen said.

Human-robot interaction, tactile sensing, outdoor environments

One area of the research focuses on health-related human-robot interaction, including embodied interaction systems designed to support older adults with mild cognitive impairment. By combining 3D vision, perception and adaptive robotic behavior, the work aims to help machines respond more naturally and effectively in real-world assistive settings. This work builds on Chen’s earlier Âé¶¹´«Ã½ Community Foundation-supported research on digital biomarkers for early screening of Alzheimer’s disease using computer vision and artificial intelligence.

Another component explores 3D tactile sensing, allowing robots to gather information through touch. This approach aims to improve how machines detect shape, movement and contact, particularly in tasks that require delicate handling or physical interaction.

The project also targets agricultural use, where robots must navigate complex outdoor environments. The research seeks to improve how machines navigate in fields, identify crops, interpret terrain, and operate under changing lighting and weather conditions.

Funding will support graduate and undergraduate student researchers, as well as equipment, computing resources and experimental testing. The project also provides opportunities for student training in robotics, computer vision and artificial intelligence.

The University of Âé¶¹´«Ã½ at Mānoa’s hosted a free public lecture in February 2026 that explored tipping points—sudden, dramatic moments when things can change quickly and unexpectedly. The presentation was delivered by Mary Lou Zeeman—professor of mathematics at Bowdoin College and co-director of the Mathematics and Climate Research Network—to an audience of approximately 150 students, faculty and community members.

Zeeman showed how tipping points show up all around us—from a boat that suddenly capsizes, to sudden mood swings, to ecosystems on the brink of collapse. Using simple math, she explained the hidden patterns behind these abrupt changes and why spotting them early matters. Understanding tipping points, she said, can help communities make smarter choices about sustainability, prepare for environmental risks, and respond more effectively when sudden problems arise.

Zeeman talked about “the type of math that can help us understand tipping points and how to use these models for decision support,” focusing on the example of healthy versus turbid lakes, but also including examples involving coral reefs, fisheries, neuroscience, energy and social media.

Faculty and students praised the talk for making complex ideas approachable.

“Zeeman showed how ideas from the frontiers of mathematical research could help us think about a wide array of challenging problems,” said Department of Mathematics faculty member Daniel Erman. “It was really exciting to see so many people engaged in these topics.”

A student who works on ecosystem resiliency, added, “This is now a new way to look at future work I do.”

The lecture was designed to be accessible to anyone curious about mathematical thinking, including middle and high school students, reflecting a growing effort to connect STEM research with the broader community.

“It was fun seeing the real mathematics that lies behind tipping points in nature,” said John Toews, a Kailua resident who attended the lecture.

The Department of Mathematics said the event is part of its ongoing effort to engage the public with real-world applications of mathematics and to spark curiosity across disciplines.

A University of Âé¶¹´«Ã½ at Mānoa researcher has received a top international honor for his work studying some of the smallest building blocks of the universe.

Chris Ketter, a postdoctoral researcher in the UH Mānoa , was awarded the Belle II PhD Technical Thesis Award. The honor was announced in February at KEK (High Energy Accelerator Research Organization), a leading high-energy physics research center in Tsukuba, Japan.

The award recognizes Ketter’s doctoral research on the Belle II K-Long and Muon detector (a system used to identify and track subatomic particles). He was selected from more than 250 PhD students involved in the global Belle II collaboration. Ketter began his research under the late Professor Gary Varner and now works with Assistant Professor Keisuke Yoshihara, focusing on particle detectors that help scientists study fundamental particles. He is expected to receive the award this summer in Vienna.

“This award came as a shock to me,” Ketter said. “I was just working hard to bring our detector up to the level or readiness required by the experiment. Now reflecting on this award, I can say it was made possible by the support and mentorship of the UH physics professors, postdoctoral researchers and engineers that I had the pleasure to work with. I am humbled by the kindness that my Âé¶¹´«Ã½ ʻohana have shown me over the years and, to that end, I am proud to receive merit highlighting the world-class research carried out at the University of Âé¶¹´«Ã½.”

The Belle II experiment brings together more than 700 researchers from around the world. Based in Japan, the project studies collisions between particles to explore fundamental questions about how the universe formed. One of its main goals is to understand why the universe today is made mostly of matter instead of equal parts matter and antimatter (particles with opposite properties). Scientists believe there may be unknown particles or forces—often called “new physics”—that could help explain this imbalance.

Âé¶¹´«Ã½Mānoa researchers play a key role in the experiment, contributing to detector systems and data collection tools that allow scientists to measure particle behavior with high precision. Ketter’s award highlights both his individual contributions and UH’s continued involvement in cutting-edge physics research on the global stage.

A University of Âé¶¹´«Ã½ at Mānoa student-led team has developed a new algorithm to help scientists determine direction in complex two-dimensional (2D) data, with potential applications ranging from particle physics to machine learning. The research was .

The algorithm development, led by undergraduate Jeffrey G. Yepez, helps scientists figure out where tiny, nearly invisible particles called neutrinos are coming from. These particles can reveal information about nuclear reactors, the sun, and faraway cosmic events. The method is based on a clever math discovery: the team found a formula that lets them match patterns in data and accurately pinpoint the direction of the source.

The students were guided by UH Mānoa Professor John G. Learned and received additional mentoring from UH alumnus and Lawrence Livermore National Laboratory staff scientist Viacheslav Li, thanks to funding from the Consortium for Monitoring, Technology and Verification. The project began with simulated neutrino data to locate nuclear reactors, and further studies are underway.

“What excites us most is that this approach gives researchers a clearer mathematical foundation for extracting direction from noisy, real-world data,” Yepez said. “It is a tool that scales with technological improvements in detectors, computing power and data volume, making it valuable far beyond the initial physics application.”

The algorithm uses a mathematical tool called the Frobenius norm to measure differences between grids of numbers, effectively acting as a “distance formula” for large data tables. By rotating a reference dataset and comparing it to measured data, the algorithm identifies the rotation that produces the smallest difference, revealing the most likely direction of the signal. Simulations show the method works especially well with high-resolution data and large datasets.

While motivated by neutrino detection, the approach could be applied across multiple fields. Potential uses include astronomy, medical imaging, weather mapping, and any system that relies on pattern recognition, offering a versatile new tool for scientists and engineers.

Other UH Mānoa authors on the paper include Jackson D. Seligman, Max A. A. Dornfest and Brian C. Crow. The Department of Physics and Astronomy is part of UH Mānoa’s .
