Zoë Kitchel

Ph.D. Student
2019-2020 Nereus Fellow, Rutgers University
Ph.D. Candidate (Rutgers University)

Zoë is working towards her PhD in the Ecology and Evolution Department at Rutgers University. After graduating from Yale College in 2015, she spent two years working in fisheries curriculum development at the University of Alaska Southeast. Now working with Dr. Malin Pinsky, Zoë is exploring the dynamics at play at range boundaries of commercial fish species, and especially how species’ traits act as a filter for environmental variability. In addition, she is a part of Rutgers’ Coastal Climate Risk and Resiliency Traineeship, aiming to bridge the gap between biologists, engineers, social scientists, and policy makers all interested in resiliency within coastal communities. She hopes for her research to push the boundaries of science, but to also be accessible to communities experiencing change first hand.

Natasha Henschke

Ph.D., Biological Oceanography

2015-2016 Princeton University

Post-Doctoral Research Fellow, Oceanography (University of British Columbia)

Natasha Henschke’s background is in biological oceanography, with her research focusing on how gelatinous zooplankton communities respond to changing oceanographic conditions. There is concern that as a result of anthropogenic factors our oceans are shifting from a fish-based to a jellyfish-based ecosystem, however recent reviews have failed to reach a consensus on whether gelatinous zooplankton abundances have been increasing worldwide. In her current work at Nereus she aims to investigate this issue by using earth system models developed at the NOAA Geophysical Fluid Dynamics Laboratory to examine the distribution and abundance of future gelatinous zooplankton populations under different climate and fishing scenarios.

Rebecca Asch

Ph.D., Biological Oceanography

2013-2016 Senior Research Fellow (Princeton University)

Assistant Professor of Fisheries Biology, East Carolina University

Rebecca Asch is a fisheries oceanographer whose research focuses on interactions between fisheries, plankton ecology, and climate. Her research combines fieldwork, time series analysis, and ecosystem modeling, spanning local-to-global and subseasonal-to-centennial scales. Rebecca’s research primarily investigates whether climate change could lead to increased seasonal mismatches between trophic levels. Many fishes spawn synchronously with plankton blooms to maximize food availability for their offspring. Seasonal timing of both fish reproduction and plankton blooms is changing under global warming, but these shifts do not always occur at the same rate. Mismatches between trophic levels can lead to lower recruitment and decreased fisheries productivity.
