Dr. Gradone is an oceanographer and marine technologist studying how ocean circulation and mixing respond to climate change. His research combines autonomous underwater gliders, shipboard observations, and numerical modeling to better understand the transport of heat, salt, oxygen, and carbon through the ocean, with a focus on the Caribbean Sea and Atlantic circulation. Joe earned … Continued
Hilde Oliver is an interdisciplinary oceanographer whose work centers on understanding physical–biological interactions in rapidly changing marine environments. She investigates these systems using a combination of ship-based in-situ measurements, global ocean observing datasets, and process-oriented numerical models. Her current research explores how increasing glacial meltwater influences phytoplankton growth in the subpolar North Atlantic and Southern … Continued
Dylan is an incoming PhD student at Rutgers University (Fall 2026) working with Dr. Corday Selden. She earned her Bachelor of Science in Marine Sciences from Texas A&M University at Galveston and focused her undergraduate research on phytoplankton ecology and biogeochemistry. Aboard R/V Falkor (too), she will help with nitrogen fixation measurements.
Dr. P. Dreux Chappell is an Associate Professor in the College of Marine Science at the University of South Florida. She has an interdisciplinary background with a BA in Biology from Amherst College and a Ph.D. in Chemical Oceanography from the MIT-WHOI Joint Program and is interested in studying the interplay between phytoplankton physiology and … Continued
Dr. Corday Selden is Co-Chief Scientist for this expedition and an Assistant Professor in the Department of Marine and Coastal Sciences at Rutgers University. Her research group, the Rutgers University Marine Biogeochemistry Lab (RUMBL), works at the intersection of ocean chemistry, microbial ecology, and climate change science. Nitrogen is the growth-limiting nutrient across most of … Continued
Bhavyaa is a researcher at Rutgers University, where she specializes in the intersection of marine biology and engineering. Her current work focuses on developing specialized instrumentation to bridge critical gaps in the study of marine microbial chemotaxis, exploring how microscopic organisms navigate their environments. She earned her B.Sc. in Microbiology from the University of Delhi … Continued
Becca Horwitz is a PhD candidate at Rutgers University studying oceanography. She is interested in the connections between physical and biological processes in coastal systems. Her work integrates a range of observational tools—including satellite products, ocean gliders, meteorological station data, and high-frequency radar—to examine both historical trends and real-time dynamics. Becca is committed to communicating … Continued
Ashley Hann is a PhD student at Rutgers University studying oceanography. She is broadly interested in using varied in situ and autonomous techniques to understand dynamic marine ecosystems while facilitating sustainable and meaningful interactions with these systems. More specifically, her research centers around the impacts of changing ocean conditions on zooplankton and the implications of … Continued
