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 鶹ý 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 鶹ý.”

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).

Several students took individual first place awards in their respective divisions defeating up to 70 other competitors in some events. This trip was designed to give the team exposure to a collegiate competition, as 鶹ý has no statewide collegiate ballroom competitions.

More about the Ballroom Dance Club

The Ballroom Dance Club offers beginner classes to all UH Mānoa students, faculty and staff in studio 2 in the athletics department from 6—7:30 p.m. on Tuesdays. No dance experience is required. For more information, or visit their Instagram page @bdcuhm.

For University of 鶹ý at Mānoa PhD student Brian Gorberg, the devastating Kona low storms weren’t just an academic research topic—they were a recurring nightmare that inundated his home three times in less than four weeks. Renting the bottom bedroom of a home in Waialua on Oʻahu’s north shore, Gorberg witnessed the final and most severe flood send an 8-foot wall of water through his place.

After experiencing two recent floods that ruined his belongings, Gorberg was seeking refuge at a friend’s house down the street when the third flood hit. The flash flooding was catastrophic, acting like a “dam spillway” through his neighborhood. The water destroyed his Jeep Patriot given to him by his dad, caused a neighboring house to spin off its foundation, and trapped another neighbor in neck-deep water.

“I got woken up by a giant wave,” Gorberg said. “I assumed the worst because I study hydrology. I assumed the dam failed and I knew I had to get out of the watershed. So, I drove all the way to the evacuation site. I actually ran up the hill because I didn’t believe the evacuation site was safe enough.”

Flooding expertise proved critical

Gorberg’s academic background proved critical during the floods. As an student in the and working with the under advisor Chris Shuler, his expertise allowed him to understand the mechanics of the disaster. During the floods, Gorberg spent hours walking through his neighborhood trying to warn residents ahead of the rising waters.

Gorberg’s current research work is to create high-end, reproducible flood models and stage height maps to better protect local communities. Working alongside undergraduate students Chiara Duyn, Megan Wong and Anne Dominique, Gorberg created a that provides residents with transparent, scenario-based flood information.

While the app and Gorberg’s maps currently focus on Windward ʻ watersheds such as Kāneʻohe, the underlying flood models are designed to be reproducible, and Gorberg aims to eventually expand this mapping to any flood zone across 鶹ý. The flood maps simulate exact inundation levels when local streams breach their banks at incremental heights—such as 12, 13 or 14 feet—allowing communities to visualize their risk and prepare for an approaching storm.

Reflecting on the tools he is building, Gorberg emphasized the urgent need for better preparedness in 鶹ý.

“Every stream gauge in the mainland has these maps. It’s not fair that 鶹ý doesn’t have it, especially considering these events,“ Gorberg said. ”And because there are graduate students like myself who have created this… that’s like the missing link in 鶹ý that would honestly solve this event, or would have been different if we had those maps.”

As an undergraduate student, Kanoa conducted a research project with Xiaolong (Leo) Geng, assistant professor in the SOEST , to measure the concentration of microplastic in coastal environments around Oʻahu. After working on this project together, Geng extended an invitation for Kanoa to join his research group as a master’s student.

“Its incredible to see how connected different reservoirs of water are in 鶹ý,” Kanoa said. “I’m very interested in addressing the challenge of modeling how this contaminant is transported on and in our islands.”

“Hope has demonstrated an exceptional ability to work across disciplines, connecting fieldwork, laboratory analysis, and environmental science outreach,” Geng shared. “She is never afraid to try new approaches, and her willingness to step outside her comfort zone has been a defining strength in her growth as a researcher.”

Now a graduate student in the Earth and Planetary Sciences program, Kanoa is expanding her research to understand microplastic concentrations in coastal environments and is also assessing riverine and oceanic environments, so as to get a more complete picture of how this contaminant is moving through 鶹ý’s water cycle.

“This degree felt like a perfect fit,” said Kanoa. “It provided the opportunity to pursue hydrology and hydrogeology in greater depth, with great potential to investigate water resources in 鶹ý.”

Improving our ability to predict and manage water quality risks in 鶹ý’s coastal zones is the focus of a University of 鶹ý at Mānoa project that was awarded a .

Coastal beaches are vital for recreation, tourism and ecosystem health; however, they are increasingly threatened by fecal contaminants. These fecal bacteria can enter beach environments through human wastewater, stormwater runoff and animal waste, accumulating in the sand and shallow groundwater. Natural coastal processes, such as tides and waves, can then mobilize and transport these contaminants across the land–sea boundary, posing risks to both public health and marine ecosystems.

This project will investigate how coastal hydrologic forces, including tidal fluctuations and wave action, influence the accumulation, movement and discharge of fecal contaminants in beach aquifers. The research team will conduct fieldwork and groundwater sampling at two beaches in 鶹ý, where fecal contamination is known to occur, and will develop advanced computer models to simulate how bacteria move through beach sediments. The findings will improve our ability to predict and manage water quality risks in coastal zones.

Xiaolong “Leo” Geng, the project’s principal investigator and assistant professor at UH’s (WRRC) and in the , will direct the project activities and supervise graduate and undergraduate students hired by this project.

“Beaches are at the heart of 鶹ý’s culture, economy and ecosystems, yet they are increasingly vulnerable to fecal contamination,” Geng said. “Our research will shed light on how bacteria move through sand and groundwater, helping to safeguard public health and marine environments. Just as importantly, we hope to inspire the next generation of scientists and strengthen community stewardship of our coastal waters.”

Geng’s co-principal investigator is Tao Yan, WRRC director.

Student and community outreach

Broader benefits of the project include training two graduate students and engaging undergraduate students through UH āԴDz’s . The team also plans to involve local communities through educational outreach and citizen science activities to support long-term coastal water stewardship in 鶹ý.

Windward Community College student Peter Scott, 18, has always been curious about the natural world. This propelled him into a nationally competitive summer research opportunity—the (REU) at the University of UH at ԴDz.

Out of more than 500 applicants across the country, only 10 were selected for the National Science Foundation funded program—and Scott was the one of only two students from 鶹ý.

“It was really a cool experience. I’m very glad I got to participate in it. It was a big confidence boost for me,” Scott said. “I got to work with a lot of really, really smart people. And it definitely helped me figure out this is something I want to do. I want to do research, I want to do science, I want to continue in this field.”

Sinking land

Scott’s project focused on why some areas of 鶹ý are sinking faster than others. By testing with an electrical current, he found that highly saturated soils and large amounts of fill may be driving subsidence in certain regions.

“It’s important to know why an area is subsiding, because that can affect how you want to plan for development,” he said. “It can affect whether or not you need to put in flood mitigation measures, or whether or not you need to change how you’re building infrastructure in an area, or whether you even want to build infrastructure in an area.”

Homeschooled since fourth grade, Scott enrolled in Windward CC’s early college program in 2023, while still in high school.

“I really enjoyed the smaller class sizes,” he said. “Going to a community college is a great place to start.”

One of Scott’s instructors, Arjun Aryal, told him about the REU program.

“Peter’s curiosity and drive for the natural sciences are impressive,” said Aryal. “As a student from Windward Community College, he met the objectives of the program: providing research experience to students from institutions with limited STEM opportunities.”

Aryal and UH ԴDz Assistant Researcher Amir Haroon served as Scott’s advisors for his research project.

Scott expects to earn an associate’s degree in the spring, then plans to continue at UH ԴDz in the fall with interests ranging from geology to botany and agriculture. One thing he is sure about his long-term goals: “I want to stay in 鶹ý, ideally, and work in the field where I can be outdoors.”
