Keeping Endangered Whales Safe By Predicting Their Movements

A College of Arts and Sciences researcher is working to develop models to predict whale behavior and prevent ship collisions.
Dan Bernardi Jan. 15, 2026

When colossal cargo vessels and whales navigate the same waters, their encounters can end in tragedy. In May 2024, aÌęÌęarrived at a New York City port with a 44-foot endangered sei whale draped across its bow—fatally struck during the voyage. Such collisions pose a catastrophic threat to endangered whale populations, including North Atlantic right whales and sei whales, which frequently feed near busy shipping lanes like those off the coasts of Massachusetts.

For massive cruise and cargo ships, changing course quickly isn’t an option. If a whale appears in their path, collisions are often unavoidable. That’s why predicting whale locations in advance is critical—allowing vessels to chart safer routes from the very beginning of their journey. This is where biologists from the College of Arts and Sciences come in.

Pinpointing when and where these collisions are most likely to occur is the focus of a research project led byÌę, a research assistant professor in the and member of professor Susan Parks’Ìę. The project is a collaboration with theÌę, the Stellwagen Bank National Marine Sanctuary, Stony Brook University and the Massachusetts Institute of Technology.

Cusano recently received grant funding from theÌęÌęandÌęÌęto lead a four-year study focused on two endangered whale species: the North Atlantic right whale—of which only about 372 individuals remain—and the sei whale, classified as depleted under the Marine Mammal Protection Act. Both species share a risky feeding behavior that puts them in the path of maritime traffic: they hunt near the ocean’s surface, making them especially vulnerable to ship strikes.

Feeding Forecast

Traditional approaches to preventing ship strikes have relied on tracking whales in real time. Cusano is taking a fundamentally different approach by developing predictive models that anticipate where whales will go next. The research combines detailed studies of whale movement patterns, both at the surface and underwater, with advanced satellite imagery that can identify concentrations of zooplankton prey from space.

“We’re essentially creating a forecasting system for whale behavior,” Cusano says. By understanding the conditions that drive feeding behavior and mapping prey hotspots from satellite data, the models aim to provide early warning systems for areas where whales are likely to congregate.

“The technology represents a significant advancement in marine conservation,” Cusano says. “Current methods often involve detecting whales after they’ve already arrived in shipping lanes, leaving little time for vessels to adjust their routes.”

The new predictive approach could provide hours or even days of advance notice, giving mariners sufficient time to implement safety measures.

The research will focus specifically on Massachusetts Bay and the Stellwagen Bank National Marine Sanctuary, areas known for both heavy shipping traffic and important whale feeding grounds. These waters serve as a natural laboratory where researchers can study the complex interactions between whale behavior, prey availability and shipping patterns.

The project’s immediate applications could transform maritime safety protocols. When models predict high probability feeding areas, shipping companies could receive automated alerts recommending reduced speeds or alternate routes. Slower vessel speeds significantly reduce the likelihood of strikes, the severity of injuries and damage to the vessel when collisions do occur.

Conservation at a Critical Moment

The timing of this research proves particularly crucial for North Atlantic right whales. Recent population assessments suggest the species may be experiencing a reproductive crisis, with fewer calves born each year and increased mortality from human activities. Every individual whale lost to ship strikes represents a significant blow to the species’ survival prospects.

The sei whale faces different but equally serious challenges. As one of the least studied large whale species, basic information about their behavior, population size and habitat requirements remains limited. They also experienceÌę at rates higher than expected. This research will contribute essential data about sei whale ecology while developing tools to protect them from collisions with ships.

Cusano’s approach reflects a new generation of conservation science that combines traditional biological research with cutting-edge technology. The integration of satellite remote sensing, behavioral ecology and predictive modeling represents the kind of interdisciplinary collaboration necessary to address complex environmental challenges.

Building Conservation Strategies

The project’s success could establish a model for protecting marine mammals in high-traffic areas worldwide. Shipping lanes intersect with critical habitat for numerous whale species across the globe, from blue whales off California to humpback whales in Australian waters.

The research will also contribute to training the next generation of marine conservation scientists at the University. Graduate students and early-career researchers working on the project will gain experience with advanced analytical techniques and collaborative approaches that define modern conservation biology.

The over $2 million investment represents more than funding for a single research project—it’s an investment in developing the scientific tools necessary to safeguard marine mammals in an increasingly crowded ocean.

“For whales hovering on the edge of extinction, this research represents an important opportunity to develop effective protection strategies,” says Cusano. “As global shipping traffic increases, the need for proactive conservation measures becomes ever more urgent.”

Dynamic Sustainability Lab Collaborates With Thomson Reuters to Build Expertise and Opportunity

The relationship began as a study of forced labor in global supply chains by Heather Panton, a Thomson Reuters executive and Maxwell graduate student.
Jessica Youngman Oct. 3, 2025

Forced labor in global supply chains may decline in coming years as Generation Z—today’s teens and young adults—gain financial influence. Unlike previous generations, they are more willing to pay a premium for products manufactured ethically.

These and other findings are the result of a two-year study by the University’s (DSL) on behalf of Thomson Reuters, a global content and technology company based in Canada.

In addition to revealing data that helps inform industry leaders, policymakers and the public, the collaboration provided valuable research and experiential learning opportunities to numerous University students engaged with the DSL.

It also laid the groundwork for a strategic collaboration that DSL Director Jay Golden says will complement the lab’s endeavors while giving students opportunities to interact with industry thought leaders and examine critical sustainability issues under the mentorship of Thomson Reuters experts.

“Given the impactful and positive experiences our students have had with the forced labor in global supply chain collaboration, we are thrilled to deepen our relationship with Thomson Reuters,” says Golden. “It provides student and faculty researchers within the Dynamic Sustainability Lab greater opportunity to tackle important real-world challenges in companies and governments around the world and come up with innovative, next-generation solutions, models and tools.”

Jay Golden

Golden founded the Maxwell-based DSL in 2021 after he joined the school as the inaugural Pontarelli Professor of Environmental Sustainability and Finance. He describes the lab as a cross-disciplinary, nonpartisan think tank that examines the “opportunities, risks and unintended consequences” that arise from the adoption of new technologies, new strategies and growing dependence on foreign-sourced resources and supply chains used in energy, climate and sustainability transitions.

Students engaged with the DSL represent a wide range of programs including many Maxwell majors. They share their data findings in government reports and technical bulletins and at sustainability symposiums the DSL hosts annually in major cities like Boston, New York City and Washington, D.C.

A Student and National Thought Leader

The DSL’s connection with Thomson Reuters began with Maxwell graduate student Heather Panton G’26 when she enrolled in the executive master’s in international relations program in Washington, D.C. Today she is senior advisor for human rights crimes and social impact at Thomson Reuters.

In 2023, Panton was awarded an Eisenhower Fellowship to advance her study of forced labor—a form of human trafficking—in global supply chains. She traveled to Malaysia and Thailand to study best practices and drive public awareness to educate consumers about making ethical purchasing decisions. She received academic guidance from Golden and shared with him a growing interest in the potential impact of up-and-coming consumers.

“When I was abroad, so many people asked about demand from the next generation,” Panton says. “Historically, American baby boomers often prioritized price, without fully considering how cost-cutting would ripple through suppliers and vendors across the supply chain. That has put pressure on companies to reduce costs in ways that sometimes affect workers’ wages and living conditions abroad. We believe Gen Z will play a critical role in shifting that dynamic by asking tougher questions, such as, ‘Was this product made with slave labor?’”

Golden was excited for the opportunity to work with Panton. Her resume included roles with the McCain Institute, the U.S. Department of State, the U.S. Department of Justice and the White House. Among them: special advisor for human trafficking and the inaugural human trafficking czar during the first Trump administration.

“She was not only our student but also a thought leader in the country,” says Golden. “I’ve learned a lot—probably more than she’s learned from me.”

Golden brought Panton’s Eisenhower Fellowship research to the DSL, where students spent the next two years expanding her work, studying generational purchasing trends, gathering data and refining her findings.

“They’re such smart students—they’re right on the mark,” she says. “We’ve worked to expand the scope of what they’re thinking about. We want them to be focused and driven, thinking about exposing things that I don’t know that many people are talking about in the mainstream. We want them to be able to present in a way that’s not only academically rigorous but also digestible—something that industry or government can consume right away.”

Presenting Research to Global Industry Leaders

The students produced a by the DSL, and a has been posted on Thomson Reuters’ website. Both share that by 2030, Generation Z will represent 17% of retail spending in the U.S., and 81% of consumers in the age group have changed their purchasing decisions based on brand actions or reputation, with 53% participating in economic boycotts.

While pursuing a bachelor’s degree in policy studies, 2024 Maxwell alumnus Ka’ai I worked as a student researcher with the DSL. He gathered information about forced labor laws across the globe, collected related policies for multi-national corporations and assisted with surveys.

“We basically did a level-set in terms of ‘How do we understand where we are at now, where are we at in terms of forced labor, and how that is affecting the market?’” says I.

The experience was empowering and prepared him for his current work with Deloitte Consulting.

“As a young professional, I’m working on many of the same things I did with the Dynamic Sustainability Lab—data analysis, survey development, stakeholder engagement,” I says. “As I navigate the professional workspace, I feel much more confident and capable going in to a pretty competitive workforce.”

Another outcome of the DSL forced labor collaboration with Thomson Reuters: two events in the 2024-25 academic year at which data findings were presented and expanded upon by subject area experts. The symposia in Washington, D.C., and in Portland, Oregon, drew representatives from footwear and apparel companies as well as government officials.

“Our students helped push the notion, ‘We are your growing customer segment,’” says Golden. Ìę“The leadership from these companies that were in attendance really acknowledged that and were receptive. The work that started with Heather has expanded to where we have the attention of the global footwear and apparel industry. It’s a rare occasion that the type of research finds its way into the mainstream in consumer decisions and draws the attention of international governments and especially the top leadership of global companies.”

Panton says the collaboration with DSL is mutually beneficial.

“The academic rigor is unbeatable,” she says of the research and resulting data. “It’s a great combination of practitioner-meets-academic—we’re taking substantive work and making it very easy for anyone in a C-suite to look at it.”

Protecting the Grid: Engineering in Action

Amid rising global urgency around digital defense, Syracuse University faculty draw on real-world expertise to prepare the next generation of cybersecurity leaders.
Dan Bernardi Sept. 22, 2025

On April 28, 2025, a major power outage affected millions across Spain, Portugal and parts of southern France due to what authorities described as a “.” Although the exact cause was not immediately confirmed, concerns quickly arose about the possibility of a cyberattack. Such trepidation highlights how in today’s interconnected world, something as simple as a phishing email can trigger a chain reaction that jeopardizes the safety and well-being of millions.

Recognizing the exponentially growing importance of cybersecurity, the College of Arts and Sciences’ (A&S’)ÌęÌę(Forensics Institute) offers a Ìęin partnership with theÌęÌę(iSchool). This program is designed to equip future professionals with the critical skills needed to safeguard sensitive information and infrastructure while holding malicious actors accountable. The M.S. blends courses in digital forensics, cybersecurity and data analytics with advanced forensic science and crime scene investigation.

What Are Cybersecurity and Digital Forensics?

While closely interconnected, these disciplines represent proactive and reactive approaches to managing digital threats. Whereas cybersecurity focuses on preventing attacks and protecting digital infrastructure, digital forensics is concerned with investigating breaches in established cybersecurity and identifying the cause, scope and perpetrators of the attack.

With digital evidence now central to over 90% of criminal cases, as reported in theÌę, the program equips students for careers in cybersecurity, digital investigations and intelligence analysis. They also gain hands-on experience through fieldwork at top-tier facilities, including federal agencies like the Federal Bureau of Investigation, the Department of Justice and the Department of Defense, along with various crime laboratories and prosecutor’s offices.

Learning from Leaders in Cybersecurity

Man
Forensics professor Filipe Augusto Da Luz Lemos visits a power transmission station in Brazil.

A key strength of the program is the access students have to faculty who are actively engaged in cutting-edge, practical research. A prime example isÌę, courtesy research professor and adjunct professor of forensics who also received a master’s degree in forensic science from A&S and a Ph.D. in cybersecurity from the Federal University of Technology ParanĂĄ in Brazil. When not teaching courses at Syracuse, he is conducting international research with organizations like the Brazilian Army at the Military Institute of Engineering.

“We focus on developing advanced simulated environments that can replicate everything from energy substations to entire distribution systems,” says Lemos about his current work. “These environments allow us to simulate cyberattacks and study system and device behavior, including the integration of physical equipment.”

Over the past decade, Lemos says the significant rise in attacks on critical infrastructure, such as theÌęÌęin 2015 and theÌęÌęin 2021, which significantly affected fuel supply to the U.S. East Coast, emphasize the growing need for highly trained professionals to work in both prevention and incident response.

Ensuring Grid Resilience

Lemos’ work in Brazil involves safeguarding that country’s power supply by exploring how systems react before, during and after an incident—without the risks or costs associated with testing real infrastructure.

“These simulations help uncover vulnerabilities, assess system resilience and evaluate the effectiveness of various detection and defense mechanisms. They also support the development of robust incident response plans and recovery protocols,” Lemos says. In turn, he brings this expertise and a deeper, more practical understanding of how to protect critical systems into the classroom at Syracuse, enriching the learning experience for students.

In his course, Computational Forensics, students are introduced to cutting-edge technologies such as machine learning and artificial intelligence. These tools are vital in the field of cybersecurity to sift through vast amounts of network traffic data to detect unusual patterns. By tackling practical forensic problems, students develop both the technical expertise and an analytical mindset essential for careers in cybersecurity and digital investigations.

Lemos sees sharing the professional knowledge he’s gained as a meaningful way to give back, recognizing the pivotal role his A&S education played in shaping his career.

“My education at Syracuse University was foundational to the work I do today,” he says. “The combination of strong theoretical grounding and hands-on experience—guided by professors who are both researchers and practitioners—gave me the tools to engage with real-world cybersecurity challenges. I’m grateful for the opportunity to support students as they prepare for impactful careers in high-stakes fields like military operations and critical infrastructure systems.”

By combining rigorous academic instruction with applied learning and direct engagement with faculty leading global initiatives, the Forensics Institute equips students to confront today’s complex digital threats. This integrated approach aligns with the University’s and A&S’s priorities of preparing students for careers in emerging and innovative technologies.

A&S Paleoclimatologists Use Ancient Sediment to Explore Future Climate in Africa

In September, extreme rains struck South Africa’s Western Cape province, flooding villages and leaving a . The catastrophic devastation is just one recent example in a string of extreme weather events that are growing more common around the world. Fueled by rising sea surface temperatures from global warming, torrential storms are increasing both in frequency and magnitude. Concurrently, global warming is also producing the opposite effect in other instances, as a mega-drought recently threatened the water supply of Cape Town in southwestern Africa to the point where residents were at risk of running out of water. This one-two punch of weather extremes are devastating habitats, ecosystems and human infrastructure.

Floodwaters

With global warming apparently here to stay, a team of paleoclimatologists from Syracuse University, George Mason University and the University of Connecticut are studying an ancient source to determine future rainfall and drought patterns: fossilized plants that lived on Earth millions of years ago.

In a led by Claire Rubbelke, a Ph.D. candidate in Earth and environmental sciences in the College of Arts and Sciences (A&S), and , Thonis Family Professor of Earth and Environmental Sciences in A&S, researchers zeroed in on the Pliocene epoch (~3 million years ago)–a time when conditions were very similar to today. Despite warmer temperatures, many parts of the world, including southwestern Africa, experienced dramatic increases in rainfall over land, likely caused by warmer than normal sea surface temperatures. This mimics a modern event called a Benguela Niño, where researchers believe shifting winds cause warm waters to move southward along the coast of Africa causing enhanced rainfall over typically arid regions.

“In the present day, the intensity and location of extreme precipitation from Benguela Niño events appear to be influenced by both Atlantic and Indian Ocean sea surface temperatures,” says Rubbelke, who is a member of Bhattacharya’s . “During the Pliocene, it appears that these Benguela Niño-like conditions may have been a permanent feature.”

The team’s work was inspired by collaborator and study co-author , associate professor in the Department of Atmospheric, Oceanic and Earth Sciences at George Mason University. Burls, an oceanographer and climate scientist from South Africa, has long been intrigued by the way geological evidence from past warm climates in Earth’s history can help researchers make sense of future rainfall and drought conditions.

“This study, which explored how past warm climates can inform us on what to expect in the future as our planet warms, brings to the fore the important role of ocean warming patterns,” says Burls. “It’s important to understand how these patterns determine the response of the hydrological cycle over southwest Africa to global warming.”

To study the impact of global warming on precipitation from millions of years in the past, the team analyzed ‘molecular fossils’ in the form of ancient leaf waxes. “These are compounds produced by leaves to protect themselves from drying out,” says Bhattacharya. “They get shed from leaf surfaces and find their way to ocean sediments, where we can extract them and study their chemical composition.”

Plants use hydrogen from rainwater to produce the waxy outer coating on their leaves, which survives in ocean sediment for millions of years. The leaf wax functions as a time capsule preserved in ocean sediment.

After transporting the millions-year-old sediment from Africa to their lab in Syracuse, Rubbelke and Bhattacharya used heat and pressure to extract lipids (e.g. fat molecules), and then used a variety of solvents to isolate the exact class of molecules that they were looking to measure. From those molecules, they determined the number of different types of hydrogen present.

“When we measure the amount of heavy and light isotopes of hydrogen in the waxes, it reveals different physical processes like increased rainfall, or how far the water vapor travels,” says Rubbelke. “We can therefore identify changes in these processes by looking at long-term changes of hydrogen.”

By comparing their data to climate models, they verify how well those models capture past climate change, which can in turn improve the accuracy of those models to predict future rainfall. As Bhattacharya notes, this is critical because climate models often disagree on whether certain regions will get wetter or drier in response to global warming.

“We are using real world data from the ancient geologic past to improve our ability to model rainfall changes as the planet warms,” she says.

The study’s third author, , assistant professor of Earth sciences at the University of Connecticut, helped analyze the comparison data and specifically examined the proposed mechanism that explains the Pliocene wet conditions in southwest Africa. She says many features of ongoing climate change are reincarnations of the past warm climates.

Rubbelke, whose interest in paleoclimate research started in high school while studying ice cores and oxygen isotopes, says that the work she is doing alongside Bhattacharya is particularly fulfilling because they are contributing valuable data to an area where there is currently a knowledge gap.

“This research is really cool because not a lot of paleoclimate records from the southern hemisphere exist, compared to the northern hemisphere at least,” says Rubbelke. “I feel like I’m really contributing to an international research effort to rectify that.”

As to whether the future will be wetter or drier in southwestern Africa, the team’s results suggests that both are possible, depending on where extreme sea surface temperatures are occurring.

While not much can be done to reverse global warming, short of cutting the use of fossil fuels completely, the researchers say this study illuminates the need for vulnerable communities to have the tools and resources to adapt to these seemingly more frequent extreme weather events.

“A key aspect of helping vulnerable communities involves improving our ability to predict hydroclimate extremes, “says Bhattacharya. “Our study directly speaks to this need, as we show that sea surface temperature patterns strongly influence climate models’ ability to predict changes in rainfall in southwestern Africa.”
