Ashley’s research focuses on the physiological adaptations that enable cetaceans to dive for extended periods of time underwater. By measuring both physiological rates and related molecular markers during resting and active behaviors, she aims to understand how cetaceans adjust their cardiovascular and metabolic processes on a fine-scale to support differing needs during diving and surfacing intervals and the limits of their physiological adaptations.
Brianna is primarily interested in marine marine and sea turtle bycatch issues, particularly working through policy mechanisms to reduce bycatch on a global scale. Currently, she focuses on assessing tuna regional fisheries management organization efforts to reducing cetacean bycatch, with an emphasis on gillnet fisheries. She is also currently exploring the effect of the MMPA Import Provisions in reducing global marine mammal bycatch through a Duke Bass Connections Project. She also has secondary interests in regulating ocean noise, which was the focus of her master’s also completed in Dr. Doug Nowacek’s lab.

Greg MerrillGreg’s dissertation research is broadly focused on assessing the impacts of plastic pollution on the energy mobilization and thermoregulatory capacities of blubber in marine mammals. His previous work has focused on investigating maternal foraging behaviors of Alaskan northern fur seals in an effort to establish an effective and relatively inexpensive long-term monitoring index of foraging success and pup survival.

Since 2007 Charlie has worked as a bioacoustics analyst characterizing the seasonal movements and distribution of whales and dolphins throughout the world’s oceans. Geospatial variation in noise exposure, bycatch, and ship strike risk was a central theme in this research. His dissertation will focus on large-scale monitoring and status assessment of river dolphins in the Amazon basin; emphasizing cost-effective methods that can be readily standardized and adopted by researchers throughout South America.

Chen-Yi’s research focuses on hydrodynamics and energetics of cetaceans. By applying computational fluid dynamics techniques to 3-D animal models, she investigates flow properties and hydrodynamic forces on the North Atlantic right whales (Eubalaena glacialis). While direct measurements of energy expenditure of large whales is unlikely, her dissertation addresses how computer solutions can help us examine the energy budget of large whales by providing the baseline drag estimations for a gliding North Atlantic right whale model and the effects of variable body shapes and poses on its hydrodynamic performance.
