As Ocean Month comes to an end, Hampton University’s Department of Marine and Environmental Science is demonstrating how research, innovation, and experiential learning are preparing the next generation of scientists to tackle some of the planet’s most pressing environmental challenges this month and beyond.
From restoring oyster reefs in the Chesapeake Bay to studying elusive leopard seals in South America and advancing sustainable aquaculture practices in Coastal Virginia, Hampton students and faculty are making meaningful contributions to the health of aquatic ecosystems near and far.
A Graduate Program Built for Discovery
At the center of these efforts is the new Hampton University’s Master of Science in Marine and Environmental Science (MES) program, which provides students with rigorous scientific training, hands-on research opportunities, and direct mentorship from faculty conducting impactful environmental research.
The program equips students with the skills needed to address complex challenges facing marine and coastal ecosystems while preparing them for careers in research, conservation, environmental policy, education, and industry. Through laboratory investigations, field studies, and collaborative partnerships, MES students gain firsthand experience solving real-world environmental issues.
“Our students are not simply learning about marine science in a classroom,” said Dean of Hampton University’s School of Science Dr. Taviare Hawkins. “They are actively contributing to scientific discoveries and environmental solutions that have implications for communities around the globe.”
The department is also expanding experiential learning opportunities through its Living Shoreline Course, sponsored by the National Fish and Wildlife Foundation. The hands-on, project-based course currently enrolls three graduate students and seven undergraduates in the Marine and Environmental Science program, providing training in living shoreline design, permitting, construction, and long-term monitoring. Through classroom instruction, field practicums, and a capstone design project, students gain practical experience in site assessment, GIS mapping, cross-section development, permit drawing standards, implementation planning, budgeting, and maintenance. The course equips future environmental professionals with the tools to develop nature-based solutions that protect coastlines, enhance habitat, and build resilience against climate change and sea-level rise.
Restoring Nature’s Water Filters
When many people think about oysters, they think about seafood. Dr. Joey Reustle wants people to see something much bigger.
“Much like coral reefs, oyster reefs are bustling neighborhoods filled with fish, crabs, shrimp, worms, and countless other species,” said Reustle. “They filter our water, reduce erosion, support local fisheries, and help coastal communities adapt to sea level rise. They’re one of the most important habitats we have in the Chesapeake Bay.”
Eastern oysters (Crassostrea virginica) create complex reef systems that sustain hundreds of species and serve as natural infrastructure for coastal ecosystems. Yet oyster reefs have declined globally by more than 85 percent due to habitat loss, pollution, climate change, and overharvesting.
Despite these challenges, oysters remain remarkably resilient and continue to play a vital role throughout the Chesapeake Bay.
At Hampton University’s REEF Lab—short for Reustle Estuarine Ecology Field Lab—researchers are exploring how oyster reef communities and food webs are influenced by environmental conditions.
Graduate student Dillon Doomstorm, a NOAA Living Marine Resources Cooperative Science Center-funded student in the MES master’s program, is currently leading an National Science Foundation (NSF)-funded project examining how urbanization and restoration efforts shape oyster reef ecosystems. This summer, the research team is conducting field experiments throughout local waterways, including the Hampton River, in partnership with the Chesapeake Bay Foundation and The Nature Conservancy.
Using stable isotope analysis, the project seeks to better understand how energy moves through oyster reef ecosystems and reveal the intricate relationships between the organisms that depend on them.
“Protecting our oceans begins close to home,” Reustle said. “Healthy oyster reefs strengthen our waterways, support biodiversity, sustain local watermen, and make our communities more resilient. And after enjoying sustainably harvested oysters, people can help by donating shells so they can be used to rebuild these critical habitats. It’s never ‘shellfish’ to love oysters.”
Studying a Top Predator of the Southern Ocean
Thousands of miles away from Hampton Roads, Hampton University researchers are helping unlock the mysteries of one of the sea’s most iconic marine mammals.
Dr. Lewallen’s research focuses on leopard seals, apex predators that play a critical role in maintaining balance throughout the Southern Ocean ecosystem. While widely recognized for their distinctive spotted coats and powerful hunting abilities, leopard seals remain among the least understood marine mammals in the world.
Her work examines the ecology, behavior, and population dynamics of these remarkable animals to better understand how changing environmental conditions may affect their food webs and biodiversity.
“Leopard seals are extraordinary indicators of the health of the Southern Ocean,” said Lewallen. “By studying how they interact with their environment, we gain valuable insights into the broader impacts of climate change on marine ecosystems and the species that depend on them.”
The research provides Hampton students with opportunities to engage with globally significant scientific questions and demonstrates how marine science connects local learning with international conservation efforts.
For students in the Master of Science in Marine and Environmental Science program, exposure to research spanning from the Chesapeake Bay to the glacial lakes of Patagonia illustrates the diverse pathways available within the field and reinforces the university’s commitment to producing scientists equipped to address environmental challenges on a global scale.
A marine mammal enthusiast, student Reyna Carrillo is conducting groundbreaking research using next-generation sequencing technologies to unlock the secrets of seal skin and understand how marine mammals adapt to frigid underwater environments.
Fully funded through an NSF award in Dr. Lewallen’s lab, Carrillo has embraced the immersive, research-driven experience that defines Hampton’s graduate program. With mentorship and support from faculty across the Department of Marine and Environmental Science, she is preparing to pursue a Ph.D. next fall while contributing important scientific insights into how seals may respond to rapid environmental change.
Preparing the Next Generation Through Aquaculture
For sophomore Marine and Environmental Science major Leila Ricks, Ocean Month represents more than scientific discovery—it reflects a growing commitment to sustainable seafood production and environmental stewardship.
A native of Hampton, Virginia, Ricks is currently serving as an Aquaculture Ambassador through Virginia Sea Grant at the Virginia Tech Virginia Seafood Agricultural Research and Extension Center (VS AREC).
There, she is gaining hands-on experience in aquaculture, one of the world’s fastest-growing and most sustainable methods of producing seafood and aquarium species.
“Aquaculture is an uprising, sustainable practice for the seafood and aquarium industry,” said Ricks.
At the Virginia Seafood AREC, researchers utilize Recirculating Aquaculture Systems (RAS), which filter and recycle water within a closed-loop system. The technology conserves water resources while protecting aquatic organisms from contaminants such as microplastics and pollution.
As an Aquaculture Ambassador, Ricks monitors water quality, participates in live feedings, assists with aquarium maintenance, conducts field work, and engages in professional development activities designed to prepare future leaders in the industry.
“This internship has taught me a plethora of skills that can be applied not just to my career but to life,” she said. “Some of these skills include working with live animals, handywork, scientific communication, and problem-solving—and I am still learning.”
Her experience highlights Hampton University’s emphasis on experiential learning and industry partnerships that allow students to apply classroom knowledge in professional settings.
A Legacy of Stewardship and Scientific Excellence
Whether restoring oyster habitats in the Chesapeake Bay, studying apex predators, or advancing sustainable aquaculture practices, Hampton University’s Department of Marine and Environmental Science continues to demonstrate the transformative power of scientific inquiry.
During Ocean Month, these projects serve as a reminder that the future of marine conservation depends on the scientists, researchers, and innovators being trained today.
“Ocean Month is a powerful reminder of both the fragility and resilience of our marine ecosystems,” said Dr. Deidre Gibson, Chair of the Department of Marine and Environmental Science. “It is a time to elevate the science, honor the stewardship already happening in our coastal communities, and showcase the work of our students and faculty who are advancing solutions for a changing ocean. At Hampton, we are preparing scholars who understand that protecting our waters is not only scientific work, but a responsibility to future generations.”
Through research, mentorship, and hands-on learning opportunities, Hampton University is preparing students not only to understand the world’s oceans—but to help protect them for generations to come.
