Ph.D., Biological Oceanography
2015-2017 Research Fellow (Princeton University)
Assistant Professor, Scripps Institution of Oceanography (University of California San Diego)
Colleen Petrik’s background is in biological oceanography and ecology, quantitatively rooted in mathematics and physics. Petrik’s research focuses on understanding how the physical environment mediates the ecology of zooplankton and commercially harvested fish and invertebrate species and the implications of climate variability and climate change on these relationships. With the Nereus Project, Petrik studied the effects of behavior and composition of crustacean zooplankton, the addition of fish early life stages, and dynamic coupling between zooplankton and fishes on the future state of global fisheries. She is now an assistant professor at the Scripps Institution of Oceanography at UC San Diego.

Nereus Fellow at Princeton University Colleen Petrik won the Science Board Best Presentation Award at the North Pacific Marine Science Organization (PICES) annual meeting, held in San Diego, from November 2 to 11.
Colleen Petrik, Senior Nereus Fellow at Princeton, visited the Stockholm Resilience Centre at the University of Stockholm from October 26 to 30 to collaborate with former Nereus Fellow James Watson.

Nereus alumnus Colleen Petrik (Texas A&M University) and Charles Stock (NOAA) are co-authors on a new paper in the journal Progress in Oceanography. They investigate how dominant factors influence the global distribution and functionality of certain commercially important fishes.
