Austin Gray joined Virginia Tech’s “Curious Conversations” to talk about microplastics and the growing body of research about their impact on human and environmental health. He shared insights related to the public perception of plastic pollution, the history of microplastics, and the direction of future research. Gray also emphasizes the importance of approaching research as public service and the need for effective science communication.Gray is an assistant professor of biological sciences and an affiliate of Virginia Tech’s Global Change Center. His research focuses on addressing questions related to environmental toxicology. He primarily uses physiological and ecological approaches to examine the impacts of legacy and emerging contaminants (microplastics, nanoplastics, and pharmaceuticals) resulting from human influence and assessing their risk to a variety of freshwater and marine organisms.

Francesco Ferretti joined Virginia Tech’s “Curious Conversations” to talk about the state of shark populations worldwide and the knowledge gaps that challenge conservation strategies. Ferretti explained the role of sharks in the larger marine ecosystem, the challenges of gathering data on shark populations, and the role citizen scientists can play in overcoming that challenge.

Ferretti is an assistant professor in the Department of Fish and Wildlife Conservation. His research interests include characterizing the history of human impact in the ocean to better understand how this has altered marine ecosystems and develop solutions for a sustainable use of marine resources. His research spans from macro-ecology to applied management and conservation with a special focus on sharks and their relatives.

Landon Marston joined Virginia Tech’s “Curious Conversations” to talk about the relationship between data centers and water usage. Marston explained the amount of water used by data centers, what they’re doing with it, and the reality of national and local impacts. He also shared aspects localities might consider before welcoming a new center.Marston is an associate professor in Virginia Tech’s Charles E. Via, Jr. Department of Civil and Environmental Engineering, where he specializes in water resources engineering. His research focuses on the sustainability of water systems and the complex interconnections between water, energy, food, and infrastructure.#virginiatech #datacenter #waterusage #waterquality #techexplained #environmentalimpact

Patrick Huber joined ⁠Virginia Tech’s “Curious Conversations”⁠ to talk about world of neutrino physics and its implications for understanding dark matter. He explained the significance of neutrinos in the universe, the methods used to detect dark matter, and emphasized the interdisciplinary nature of the research.

Huber is the William E. Hassinger, Jr. Senior Faculty Fellow in the ⁠College of Science⁠, a professor of physics, and director of the Center for Neutrino Physics. His research focuses on neutrino physics and he has helped build an internationally recognized program that has implications for basic science and applications to global and national security.

Mike Mollenhauer joined Virginia Tech’s “Curious Conversations” to talk about how smart mobility and infrastructure are influencing the future of transportation. He explained the use of real-time data, adaptive speed control, and automated driving systems to enhance transportation safety and efficiency. He also shared the work he and his colleagues are doing related to real-time traffic management, variable speed limits, and the integration of automated vehicles with smart infrastructure.Mollenhauer is the Director of the Center for Technology Implementation at the Virginia Tech Transportation Institute. He oversees the center's aspects of business and product development, including management of product development teams, leading business and product roadmap development activity, project management for commercial and government contracts, as well as evaluating in-vehicle technologies and quantifying driver safety behaviors.#virginiatech #transportation #RoadSafety #SmartMobility #TrafficTechnology #TrafficInnovation #AI #DataDriven #RoadSafety #SmartCities #futureoftransportation

In 2025, Virginia Tech’s “Curious Conversations” featured more than 30 researchers sharing their expertise. We learned about everything from the future of airspace, mitigating online threats, and curing cancer with air bubbles to the neuroscienceof dancing, the importance of ghost stories, the history of Christmas music, and much more.

We’re so thankful each one took the time to chat with us, and excited for even more "Curious Conversations" coming in 2026!

Ariana Wyatt joined Virginia Tech’s “Curious Conversations” to talk about the history of Christmas music, from its origins in early Christian hymns to its transformation into a commercialized genre in the 20th century. She shared the cultural impact of Christmas music, the distinction between church hymns and secular songs, and the nostalgia that these tunes evoke during the holiday season. Wyatt is associate dean for outreach and engagement and associate professor of voice in Virginia Tech’s College of Architecture, Arts, and Design. A graduate of Juilliard Opera Center, she has performed in operas and concert halls throughout the country and her research focuses on vocal diction and acting as well as opera research and production.

Andrew McCoy joined Virginia Tech’s “Curious Conversations” to talk about 3D printing concrete homes as a potential solution for current housing challenges. He shared the current landscape of housing in Virginia and how this emerging technology might be harnessed to reduce costs and improve efficiency. He broke down how this building process works, the challenges of attempting to shift to it, and how he and his colleagues are working to overcome those hurdles.McCoy, the Beliveau Professor in the Department of Building Construction, is associate director for research and innovation for the Myers-Lawson School of Construction and director of the Virginia Center for Housing Research at Virginia Tech. His research focuses on pioneering solutions using industrialized construction, 3D concrete printing, and smart housing technologies with a goal of building housing that’s smarter, faster, and fairer for all.
