Studying glaciers . . . from Florida

On the surface, the University of Florida seems an unlikely place to find cutting-edge research on ice sheets.

But Emma “Mickey” MacKie says this is the perfect place for her work — thanks in large part to HiPerGator, one of the fastest supercomputers in higher education.

MacKie, an assistant professor of geological sciences and glaciologist, joined UF in August 2021 and said her decision hinged largely on access to HiPerGator and the university’s focus on machine learning and artificial intelligence technologies. MacKie uses machine learning methods to study subsurface conditions of glaciers in polar regions and access to a powerful supercomputer is crucial given the large data sets her research generates.

“I'm very happy to be in a place with lots of people who are working on different types of problems and are interested in developing these different tools,” MacKie said. “There are a number of members of my department in geology who are studying glacial geology through different lenses. And so, there's all of this complementary geological and machine learning knowledge at UF that I'm very excited to bring together.”

MacKie has set up the Gator Glaciology Lab, where she and a team of seven undergraduate students from the fields of geology, computer science, physics, math and data science are using AI to analyze what lies beneath glaciers and how they are moving and melting.

“Our work is part of a bigger effort in the glaciology community to start working on quantifying our uncertainty in future sea-level rise projections so that we can give policy makers this information.”

It’s a very difficult challenge, MacKie said, because of limited access to polar regions and the miles-thick ice covering the ground. Then there is the scale of ice sheets; Antarctica, for example, is the size of U.S. and Mexico combined.

Measurements of the topography below such glaciers are gathered using radars mounted on airplanes to “see” through ice. Her team then uses HiPerGator to simulate realistic looking topography in places where there are gaps or blank spots in the measurements. They generate hundreds of maps to represent different possible ice sheet conditions, which could be used to determine numerous possible sea level rise scenarios.

“Our work is part of a bigger effort in the glaciology community to start working on quantifying our uncertainty in future sea-level rise projections so that we can give policy makers this information,” she said.

Earlier this spring, MacKie swapped out her flip-flops for snow boots to study subsurface glacial conditions in Svalbard, which is next to northeastern Greenland. Visiting Svalbard will help her test and develop data collection and analysis techniques that could be applied to Antarctica or Greenland, which both contain large ice sheets that could have serious environmental impacts if they experience significant melting.

In Svalbard, MacKie and Norwegian researchers from the University of Bergen and the University Centre in Svalbard took seismic and radar measurements of glaciers that will be used to make estimates about conditions beneath the ice.

Among glaciers of concern is the Thwaites “Doomsday Glacier,” which is losing the most ice of any glacier in Antarctica. There are signs showing Thwaites’ ice shelf could start to break in the next few years. MacKie said it will likely be a few hundred years before the glacier could undergo significant collapse and jeopardize the West Antarctica Ice Sheet, leading to several meters of sea level rise.

The effects of Thwaites and other ice sheet melts in Antarctica and Greenland will become apparent in decades to come, with the potential for a meter of sea level rise by the end of the century, which MacKie and other researchers hope to predict more accurately.

“The state of Florida has the most to lose when sea level rises,” she said in an episode of the From Florida podcast. “And so, I think we have a lot of skin in the game and it’s really important to be studying this question here in Florida.”

How a UF reading program is reaching classrooms worldwide

For more than 25 years, Holly Lane, Ph.D., has been laser-focused on a global educational goal: to ensure that students worldwide have access to information about reading. Her passion project, known as the University of Florida Literacy Institute, or UFLI, has already improved the literacy skills of more than 10 million children. What began as a modest classroom tool now has a Facebook community of over 273,000 members; 18 million online toolbox views; and more than 500,000 instructional manuals in classrooms. And as the UFLI brand gains traction, Lane continues to champion what the acronym means and why the program has been so life-changing. “When you learn to read, you fly,” said Lane, who serves as the UFLI director and a professor of special education at UF. UFLI is an ongoing effort by UF faculty and students to improve literacy outcomes for struggling students by addressing two key areas: reader development and teacher development. The program began in 1998 as a tutoring model for beginning readers working with Lane’s pre-service teachers. The idea was that, if teachers understood how to employ effective, evidence-based practices in a one-on-one tutoring session, they could transfer those skills to their small-group or classroom instruction. However, some teachers struggled to make that transition, so a dedicated small-group lesson model was created. That foundation eventually expanded into a dyslexia support program and caught the attention of a surprising partner, best-selling author and philanthropist James Patterson. Known worldwide for his literacy advocacy and generous support of reading initiatives, Patterson has become a key benefactor for the program. When the COVID-19 pandemic hit, a challenge turned into a breakthrough. UFLI started its Virtual Teaching Resource Hub and, in the first week, about 70,000 teachers visited the site and downloaded materials. The turning point came when a school in St. Augustine reached out to UFLI, asking for professional development. “I said, ‘Well, what if we planned the lessons for you instead of teaching you how to plan these lessons?’” Lane said. What followed was what Lane called her “accidental phonics program.” “They ended the year with the best scores they'd ever seen, better than their pre-COVID scores, and that was unheard of,” Lane said. That success led to an effective district-wide pilot in Alachua County with 21 elementary schools. UFLI leaders decided to publish the contents of the program and create a manual that individual teachers could purchase. This concept boomed, and the program even made waves overseas. “Starting with the virtual teaching hub… we had a huge following in Perth and in Melbourne, and now we have an Australian edition of the manual,” Lane said. “We’ve been in every state and every Canadian province and territory, but we're also now in something like 60-some other countries.” Patterson has continued his support by directing efforts toward expanding UFLI’s reach in Florida, aiming to bring the program to every district in the state. Looking ahead, Lane is especially excited about UFLI’s new technology. “We're calling it our assessment and planning portal,” Lane said. “Teachers assess two skills a week, and they enter their data into this program and it spits out small-group lesson plans for the following week that target specific needs of their students.” The data input system is highly advanced, requiring the teacher to simply hold up work in front of a webcam, and the system then reads the student handwriting and imports the data. The program’s structure also ensures that students apply new concepts daily and revisit them regularly. But behind it all is a deeply connected community. For Lane, the success of UFLI boils down to people. “We have an amazing team here,” Lane said. “If anything, that's my superpower, finding really good people who are really good humans but also really good at what they do.” For more information about UFLI, visit ufli.education.ufl.edu.

Workplace jargon hurts employee morale, collaboration, study finds

You’ve probably heard it before in a meeting: “Let’s touch base offline to align our bandwidth on this workflow.” Corporate jargon like this is easy to laugh at — but its negative impact in the office can be serious. According to a new study, using too much jargon in the workplace can hurt employees’ ability to process messages, leading them to experience negative feelings and making them feel less confident. In turn, they’re less likely to reach out and ask for or share information with their colleagues. “You need people to be willing to collaborate, share ideas and look for more information if they don't understand something at work,” said Olivia Bullock, Ph.D., an assistant professor of advertising at the University of Florida and co-author of the new study. “And jargon might actually be impeding that information flow across teams.” Age made a difference, though. Older workers had a harder time processing jargon, but were more likely to intend to ask for more information to clarify the message. Younger employees were less likely to seek and share information when confused by jargon. “It gives credence to the idea that younger people are more vulnerable to these workplace dynamics,” Bullock said. “If you're onboarding younger employees, explain everything clearly.” Bullock and her co-author, Tiffany Bisbey, Ph.D., an assistant professor at George Washington University, published their findings Aug. 25 in the International Journal of Business Communication. An expert in communication research, Bullock has long studied jargon’s negative effects for talking about health and science. Then, faced with jargon in her own work, she started to ask how these arcane, technical words might get in the way of a smooth workplace. To find out, Bullock surveyed nearly 2,000 people who were told to imagine they had just started a new job and received an email with important directions. Half had to navigate a jargon-filled message about “intranets” and “EFT” payments. The other half had that jargon translated back into plainer language. The message packed with jargon, not surprisingly, made it harder for people to process the information, which can throw off an entire workday. “It doesn't just make them feel bad about the information they've been given. It makes them feel bad about themselves,” Bullock said. The study then asked people how they would respond to the jargon. The impenetrable language made them feel insecure and less likely to ask for help right when they needed it the most. “They weren’t as willing to collaborate,” Bullock said. “If you can’t ask for more information or share that information downstream, you’re creating silos, and that’s disrupting your workflow and environment.” Having studied jargon for so long, Bullock has one piece of advice for employers and employees alike. “Always reduce jargon,” she said. “The benefit of using jargon doesn’t outweigh the cost.”

With lasers, smoke and a wind tunnel, UF helps federal agency investigate deadly Hurricane Maria

As Floridians brace for hurricanes amid the wild weather of 2025, some University of Florida researchers have their eyes on 2017’s Hurricane Maria, the deadly Category 4 storm that pummeled Puerto Rico. Engineering professor and natural hazards researcher Brian Phillips, Ph.D., is leading UF’s efforts in a Hurricane Maria investigation conducted by the National Institute of Standards and Technology, known as NIST. The goal is increased safety and resilience amid deadly conditions. Maria killed nearly 3,000 people and caused more than $90 billion in damage. Most of the island’s wind sensors and weather stations failed as the storm raged, leaving responders and investigators with few reliable weather measurements. What went wrong? Phillips and UF storm researchers are helping answer that question — and provide safety and structural recommendations — as part of NIST’s Hurricane Maria investigation. The full report will be released in 2026, but NIST recently published preliminary findings; some of the hazard and structural load data was derived from wind tunnel tests at UF's NHERI Experimental Facility in the Powell Family Structure and Materials Laboratory on UF’s East Campus in Gainesville. “Our wind tunnel has a strong reputation in the wind-engineering community for its unique flow control and measurement capabilities We worked with NIST to develop a test campaign to study the wind conditions Puerto Rico’s mountainous terrain and the resulting loads of critical infrastructure,” said Phillips, a civil and coastal engineering professor with UF’s Engineering School of Sustainable Infrastructure & Environment. “UF,” he added, “has one of the premier research wind tunnels in the country and it enables us to pursue impactful research like this.” As part of the NIST investigation, Phillips and his team created 1-to-3100 scale topographic models of regions in Puerto Rico — about 12 kilometers shrunk down to four meters, Phillips said. They set up those models in the wind tunnel and replicated wind flow over the topography. “These initial tests were designed to understand the influence of the complex topography had on the wind,” Phillips said. Flow was measured using velocity probes and particle image velocimetry (PIV). These topographic model tests were followed by 1-to-100 scale tests on models of two hospitals in Puerto Rico. In addition to surface pressure measurements, the team conducted qualitative flow visualization tests using smoke, lasers, and high-speed cameras. “The capabilities of the UF wind tunnel enabled us to investigate the hurricane winds at two different scales,” said NIST’s lead Hurricane Maria investigator, Joseph Main, “so we could measure how the winds were accelerated by Puerto Rico’s mountainous topography and then how those winds translated into loads on critical buildings.” Maria’s flooding blocked roads to hospitals and shelters. The hospitals themselves were heavily damaged by the storm, NIST reported. Reduced access to healthcare was a major factor in the death toll. “It's good to take a step back,” Phillips said about the overall investigation. “Researchers are approaching the disaster from multiple angles, including the better understanding of the hazard, the performance of critical infrastructure, public response and recovery. “This holistic approach is needed to capture the complete picture and maximize what we can learn from the event. UF's primary contribution was understanding the hurricane wind field and the resulting structural loads, which is a critical piece of that puzzle.” In finding infrastructure vulnerabilities, researchers contend the goal is integrating their findings into design standards for Puerto Rico’s unique topography and building codes. The findings also could be valuable to other storm-prone regions with complex topography. NIST launched the investigation in 2018, noting Hurricane Maria “set off a cascade of building and infrastructure failures across Puerto Rico that had lasting impacts on society, including health care, business and education.” “Our goal is to learn from that event to recommend improvements to building codes, standards and practices that will make communities more resilient to hurricanes and other hazards, not just in Puerto Rico but across the United States,” Main said. The complete report is scheduled to be released in 2026, and NIST noted some findings may change before its release. But in July, NIST released some preliminary findings. They include: Peak wind speeds over flat terrain reached 140 mph. They accelerated to over 200 mph in some areas due to the steep hills and mountains. The mountains also intensified the rainfall, which reached 30 inches in some areas. Only three out of 22 weather stations were fully functional during the hurricane. 95.3% of schools on the island lost power for an average of over 100 days. “One important preliminary finding from the study is that emergency preparations work,” NIST reported. “Businesses, schools and hospitals that took specific measures to prepare before Hurricane Maria were able to resume operations more quickly” said Maria Dillard, NIST’s associate lead Hurricane Maria investigator. Preparations included pre-established emergency plans, designated risk mitigation funds and backup power sources.
